WHICH FOODS ARE RICHEST IN (i) RIBOFLAVIN?
(i) Riboflavin plays an important role in our daily diet and can be found naturally in many foods.
Foods rich in (i) Riboflavin can be obtained from both animal and plant sources.
Firstly, milk and dairy products are among the foods rich in (i) Riboflavin.

Yogurt, cheese, and milk, in particular, play an important role in meeting (i) Riboflavin needs.
Among animal sources, eggs, liver, and kidneys also have a high (i) Riboflavin content.
These foods are also high in (i) Riboflavin.

Regarding plant sources, leafy green vegetables are quite rich in (i) Riboflavin.
Dark green leafy vegetables such as spinach, broccoli, asparagus, and Brussels sprouts stand out for their (i) Riboflavin properties .
In addition, nuts such as almonds and hazelnuts, and whole grains can also be considered natural sources of (i) Riboflavin.

Some vegetables, like mushrooms, are also rich in (i) Riboflavin and make excellent sources for vegan or vegetarian diets.
Additionally, avocados are another valuable vegetable containing (i) Riboflavin and offer numerous health benefits .

In general, (i) Riboflavin is considered an essential nutrient in the body that helps with energy production and assists cells in coping with oxidative stress.
A varied and balanced diet is important for adequate (i) Riboflavin intake.
Including (i) Riboflavin-rich foods in your daily diet will help support your overall health and energy levels.

WHAT ARE THE CONSEQUENCESof (i) RIBOFLAVIN DEFICIENCY?
(i) Riboflavin , also known as vitamin B2, is vital for the healthy functioning of the body.
A deficiency can lead to various health problems.
Here are some possible conditions that a (i) Riboflavin deficiency can cause:

Mouth and Tongue Problems
(i) Riboflavin deficiency can cause problems such as cracks and sores at the corners of the mouth, redness and swelling of the tongue.
Symptoms such as oral inflammation and scaling of the lips may also occur.

Skin Problems
Deficiency can lead to dry, scaly rashes and skin inflammation (such as seborrheic dermatitis).
Areas where sebaceous glands are active, such as the nose, forehead, and cheeks, are particularly prone to these types of skin problems.

Eye Health Problems
(i) Riboflavin deficiency can cause problems such as burning, itching, light sensitivity, and vision problems in the eyes.
Long-term deficiency can increase the risk of developing cataracts.

Iron Deficiency Anemia
(i) Riboflavin helps the body utilize iron, and its deficiency can indirectly lead to iron deficiency anemia.
Anemia manifests itself with symptoms such as fatigue, shortness of breath, and low energy levels.
Deficiency symptoms usually result from long-term (i) Riboflavin deficiency, which is why a regular and balanced diet, including the consumption of foods rich in vitamin B2, is very important.

WHAT HAPPENS IF YOU TAKE TOO MUCH (i) RIBOFLAVIN?
(i) Riboflavin , also known as vitamin B2, is a water-soluble vitamin, and excessive intake generally does not cause serious side effects because the body excretes excess (i) Riboflavin through urine.
However, like any nutrient, (i) Riboflavin can have some harmful effects when consumed above a certain limit.

Excessive consumption of (i) Riboflavin, especially when taken in supplement form, can cause allergic reactions in some people.
These reactions typically include skin problems such as itching and redness.
Additionally, high doses of (i) Riboflavin can cause urine to become intensely yellow, which is usually harmless and indicates that the body is processing and eliminating the excess (i) Riboflavin.

However, (i) Riboflavin is important to consult a healthcare professional before taking any dietary supplements, especially if you have existing health conditions or are taking regular medication.
(i) Riboflavin may interact with certain medications, potentially leading to some health problems.
For example, (i) Riboflavin may reduce the effectiveness of some cancer treatments.

Generally, (i) Riboflavin obtained through diet poses no health risks.
In fact, (i) Riboflavin from natural food sources is very important for overall health, and especially for the health of the eyes, skin, and nervous system.
Including vitamin B2-rich foods in your diet in a balanced way is sufficient to safely provide the (i) Riboflavin your body needs.

So, if you're eating a balanced and varied diet without supplements, you're unlikely to have a (i) Riboflavin excess.
However, if you're considering supplements, be sure not to exceed the recommended dosage and consult a dietitian or doctor to determine the appropriate course of action based on your health condition.
With any health changes, including medications and supplements, it's always best to seek professional advice.

HISTORY of (i) RIBOFLAVIN:
The name "(i) Riboflavin" comes from "ribose" (the sugar whose reduced form, ribitol, forms part of its structure) and "flavin", the ring-moiety that imparts the yellow color to the oxidized molecule (from Latin flavus, "yellow").
The reduced form, which occurs in metabolism along with the oxidized form, appears as orange-yellow needles or crystals.

The earliest reported identification, predating any concept of vitamins as essential nutrients, was by Alexander Wynter Blyth.
In 1879, Blyth isolated a water-soluble component of cows' milk whey, which he named "lactochrome", that fluoresced yellow-green when exposed to light.

In the early 1900s, several research laboratories were investigating constituents of foods, essential to maintain growth in rats.
These constituents were initially divided into fat-soluble "vitamine" A and water-soluble "vitamine" B. (The "e" was dropped in 1920.)
Vitamin B was further thought to have two components, a heat-labile substance called B1 and a heat-stable substance called B2.

Vitamin B2 was tentatively identified to be the factor necessary for preventing pellagra, but that was later confirmed to be due to niacin (vitamin B3) deficiency.
The confusion was due to the fact that (i) Riboflavin (B2) deficiency causes stomatitis symptoms similar to those seen in pellagra, but without the widespread peripheral skin lesions.
For this reason, early in the history of identifying (i) Riboflavin deficiency in humans the condition was sometimes called "pellagra sine pellagra" (pellagra without pellagra).

In 1935, Paul Gyorgy, in collaboration with chemist Richard Kuhn and physician T. Wagner-Jauregg, reported that rats kept on a (i) Riboflavin-free diet were unable to gain weight.
Isolation of (i) Riboflavin from yeast revealed the presence of a bright yellow-green fluorescent product that restored normal growth when fed to rats.
The growth restored was directly proportional to the intensity of the fluorescence.

This observation enabled the researchers to develop a rapid chemical bioassay in 1933, and then isolate the factor from egg white, calling it ovoflavin.
The same group then isolated a similar preparation from whey and called it lactoflavin.
In 1934, Kuhn's group identified the chemical structure of these flavins as identical, settled on "(i) Riboflavin" as a name, and were also able to synthesize the vitamin.

Circa 1937, (i) Riboflavin was also referred to as "Vitamin G".
In 1938, Richard Kuhn was awarded the Nobel Prize in Chemistry for his work on vitamins, which had included B2 and B6.

In 1939, it was confirmed that (i) Riboflavin is essential for human health through a clinical trial conducted by William H. Sebrell and Roy E. Butler.
Women fed a diet low in (i) Riboflavin developed stomatitis and other signs of deficiency, which were reversed when treated with synthetic (i) Riboflavin.
The symptoms returned when the supplements were stopped

SOURCES of (i) RIBOFLAVIN:
The United States Department of Agriculture, Agricultural Research Service maintains a food composition database from which (i) Riboflavin content in hundreds of foods can be searched
The white flour produced after milling of wheat has only 67% of its original (i) Riboflavin amount left, so white flour is enriched in some countries.

(i) Riboflavin is also added to ready-to-eat breakfast cereals.
(i) Riboflavin is difficult to incorporate (i) Riboflavin into liquid products because it has poor solubility in water, hence the requirement for (i) Riboflavin-5'-phosphate (FMN, also called E101 when used as colorant), a more soluble form of (i) Riboflavin.

The enrichment of bread and ready-to-eat breakfast cereals contributes significantly to the dietary supply of the vitamin.
Free (i) Riboflavin is naturally present in animal-sourced foods along with protein-bound FMN and FAD.
Cows' milk contains mainly free (i) Riboflavin, but both FMN and FAD are present at low concentrations.

FORTIFICATION of (i) RIBOFLAVIN:
Some countries require or recommend fortification of grain foods.
As of 2024, 57 countries, mostly in North and South America and southeast Africa, require food fortification of wheat flour or maize (corn) flour with (i) Riboflavin or (i) Riboflavin-5'-phosphate sodium.
The amounts stipulated range from 1.3 to 5.75 mg/kg.
An additional 16 countries have a voluntary fortification program.
For example, the Indian government recommends 4.0 mg/kg for "maida" (white) and "atta" (whole wheat) flour.

ABSORPTION, METABOLISM, EXCRETION of (i) RIBOFLAVIN:
More than 90% of (i) Riboflavin in the diet is in the form of protein-bound FMN and FAD.
Exposure to gastric acid in the stomach releases the coenzymes, which are subsequently enzymatically hydrolyzed in the proximal small intestine to release free (i) Riboflavin.
Absorption occurs via a rapid active transport system, with some additional passive diffusion occurring at high concentrations.

Bile salts facilitate uptake, so absorption is improved when the vitamin is consumed with a meal.
The majority of newly absorbed (i) Riboflavin is taken up by the liver on the first pass, indicating that postprandial appearance of (i) Riboflavin in blood plasma may underestimate absorption.

Three (i) Riboflavin transporter proteins have been identified: RFVT1 is present in the small intestine and also in the placenta; RFVT2 is highly expressed in brain and salivary glands; and RFVT3 is most highly expressed in the small intestine, testes, and prostate.
Infants with mutations in the genes encoding these transport proteins can be treated with (i) Riboflavin administered orally.

(i) Riboflavin is reversibly converted to FMN and then FAD.
From (i) Riboflavin to FMN is the function of zinc-requiring (i) Riboflavin kinase; the reverse is accomplished by a phosphatase.
From FMN to FAD is the function of magnesium-requiring FAD synthase; the reverse is accomplished by a pyrophosphatase.

FAD appears to be an inhibitory end-product that down-regulates its own formation.
When excess (i) Riboflavin is absorbed by the small intestine, it is quickly removed from the blood and excreted in urine.
Urine color is used as a hydration status biomarker and, under normal conditions, correlates with urine specific gravity and urine osmolality.

However, (i) Riboflavin supplementation in large excess of requirements causes urine to appear more yellow than normal.
With normal dietary intake, about two-thirds of urinary output is (i) Riboflavin, the remainder having been partially metabolized to hydroxymethylriboflavin from oxidation within cells, and as other metabolites.
When consumption exceeds the ability to absorb, (i) Riboflavin passes into the large intestine, where it is catabolized by bacteria to various metabolites that can be detected in feces.

REDOX REACTIONS of (i) RIBOFLAVIN:
Redox reactions are processes that involve the transfer of electrons.
The flavin coenzymes support the function of roughly 70-80 flavoenzymes in humans (and hundreds more across all organisms, including those encoded by archeal, bacterial and fungal genomes) that are responsible for one- or two-electron redox reactions which capitalize on the ability of flavins to be converted between oxidized, half-reduced and fully reduced forms.
FAD is also required for the activity of glutathione reductase, an essential enzyme in the formation of the endogenous antioxidant, glutathione.

MICRONUTRIENT METABOLISM of (i) RIBOFLAVIN:
(i) Riboflavin, FMN, and FAD are involved in the metabolism of niacin, vitamin B6, and folate.
The synthesis of the niacin-containing coenzymes, NAD and NADP, from tryptophan involves the FAD-dependent enzyme, kynurenine 3-monooxygenase.
Dietary deficiency of (i) Riboflavin can decrease the production of NAD and NADP, thereby promoting niacin deficiency.

Conversion of vitamin B6 to its coenzyme, pyridoxal 5'-phosphate, involves the enzyme, pyridoxine 5'-phosphate oxidase, which requires FMN.
An enzyme involved in folate metabolism, 5,10-methylenetetrahydrofolate reductase, requires FAD to form the amino acid, methionine, from homocysteine.

(i) Riboflavin deficiency appears to impair the metabolism of the dietary mineral, iron, which is essential to the production of hemoglobin and red blood cells.
Alleviating (i) Riboflavin deficiency in people who are deficient in both (i) Riboflavin and iron improves the effectiveness of iron supplementation for treating iron-deficiency anemia.

SYNTHESIS of (i) RIBOFLAVIN:
Biosynthesis
Biosynthesis takes place in bacteria, fungi and plants, but not animals.
The biosynthetic precursors to (i) Riboflavin are ribulose 5-phosphate and guanosine triphosphate.
The former is converted to L-3,4-dihydroxy-2-butanone-4-phosphate.

Guanosine is degraded to 4-hydroxy-2,4,5-triaminopyrimidine, which is transformed into 5-amino-6-(D-ribitylamino)uracil.
These two compounds are then the substrates for the penultimate step in the pathway, catalysed by the enzyme lumazine synthase in reaction EC 2.5.1.78.
In the final step of the biosynthesis, two molecules of 6,7-dimethyl-8-ribityllumazine are combined by the enzyme (i) Riboflavin synthase in a dismutation reaction.

This generates one molecule of (i) Riboflavin and one of 5-amino-6-(D-ribitylamino) uracil.
The latter is recycled to the previous reaction in the sequence.
Conversions of (i) Riboflavin to the cofactors FMN and FAD are carried out by the enzymes (i) Riboflavin kinase and FAD synthetase acting sequentially

INDUSTRIAL SYNTHESIS of (i) RIBOFLAVIN:
The industrial-scale production of (i) Riboflavin uses various microorganisms, including filamentous fungi such as Ashbya gossypii, Candida famata and Candida flaveri, as well as the bacteria Corynebacterium ammoniagenes and Bacillus subtilis.
B. subtilis that has been genetically modified to both increase the production of (i) Riboflavin and to introduce an antibiotic (ampicillin) resistance marker, is employed at a commercial scale to produce (i) Riboflavin for feed and food fortification.

By 2012, over 4,000 tonnes per annum were produced by such fermentation processes.
In the presence of high concentrations of hydrocarbons or aromatic compounds, some bacteria overproduce (i) Riboflavin, possibly as a protective mechanism.
One such organism is Micrococcus luteus (American Type Culture Collection strain number ATCC 49442), which develops a yellow color due to production of (i) Riboflavin while growing on pyridine, but not when grown on other substrates, such as succinic acid.

LABORATORY SYNTHESIS of (i) RIBOFLAVIN:
The first total synthesis of (i) Riboflavin was carried out by Richard Kuhn's group.
A substituted aniline, produced by reductive amination using D-ribose, was condensed with alloxan in the final step.
