C16 Palmitic Acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain.
C16 Palmitic Acid is the most common saturated fatty acid found in animals, plants and microorganisms.
Its chemical formula is CH3(CH2)14COOH, and its C:D (the total number of carbon atoms to the number of carbon-carbon double-bonds) is 16:0.
C16 Palmitic Acid is a major component of the oil from the fruit of oil palms (palm oil), making up to 44% of total fats.
Meats, cheeses, butter, and other dairy products also contain palmitic acid, amounting to 50–60% of total fats.
Palmitates are the salts and esters of palmitic acid.
The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4).
Occurrence and production of C16 Palmitic Acid
C16 Palmitic Acid was discovered by Edmond Frémy in 1840, in saponified palm oil.
This remains the primary industrial route for its production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water and the resulting mixture fractionally distilled.
C16 Palmitic Acid is produced by a wide range of other plants and organisms, typically at low levels.
C16 Palmitic Acid is present in butter, cheese, milk, and meat, as well as cocoa butter, olive oil, soybean oil, and sunflower oil.
Karukas contain 44.90% C16 Palmitic Acid.
The cetyl ester of C16 Palmitic Acid (cetyl palmitate) occurs in spermaceti.
Biochemistry of C16 Palmitic Acid
Excess carbohydrates in the body are converted to C16 Palmitic Acid.
C16 Palmitic Acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids.
As a consequence, C16 Palmitic Acid is a major body component of animals.
In humans, one analysis found it to make up 21–30% (molar) of human depot fat, and it is a major, but highly variable, lipid component of human breast milk.
Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC), which is responsible for converting acetyl-CoA to malonyl-CoA, which in turn is used to add to the growing acyl chain, thus preventing further palmitate generation.
Some proteins are modified by the addition of a palmitoyl group in a process known as palmitoylation.
Palmitoylation is important for localisation of many membrane proteins.
Applications of C16 Palmitic Acid
Surfactant
C16 Palmitic Acid is used to produce soaps, cosmetics, and industrial mold release agents.
These applications use sodium palmitate, which is commonly obtained by saponification of palm oil.
To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate.
Foods
Because it is inexpensive and adds texture and "mouthfeel" to processed foods (convenience food), C16 Palmitic Acid and its sodium salt find wide use in foodstuffs.
Sodium palmitate is permitted as a natural additive in organic products.
Military
Aluminium salts of palmitic acid and naphthenic acid were the gelling agents used with volatile petrochemicals during World War II to produce napalm.
The word "napalm" is derived from the words naphthenic acid and palmitic acid.
C16 Palmitic Acid is a saturated long-chain fatty acid with a 16-carbon backbone.
C16 Palmitic Acid is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat.
C16 Palmitic Acid, or hexadecanoic acid is one of the most common saturated fatty acids found in animals and plants, a saturated fatty acid found in fats and waxes including olive oil, palm oil, and body lipids.
C16 Palmitic Acid occurs in the form of esters (glycerides) in oils and fats of vegetable and animal origin and is usually obtained from palm oil, which is widely distributed in plants. C16 Palmitic Acid is used in determination of water hardness and is an active ingredient of *Levovist*TM, used in echo enhancement in sonographic Doppler B-mode imaging and as an ultrasound contrast medium.
Use and Manufacturing of C16 Palmitic Acid
Found as glycerol ester in oils and fats; Produced from palm oil, Japan wax, or Chinese vegetable tallow; [Merck Index] Very common naturally occurring fatty acid; Used to make metallic palmitates and esters; in soaps and cosmetics; in lube oils; for waterproofing; in food-grade additives; as a non-drying oil (surface coating)

C16 Palmitic Acid, also known as C16 or hexadecanoate, belongs to the class of organic compounds known as long-chain fatty acids.
These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms.
C16 Palmitic Acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
C16 Palmitic Acid is a potentially toxic compound.
C16 Palmitic Acid, also known as cetyl or hexadecanoic acid, is a saturated fatty acid found in abundance in plants and animals.
C16 Palmitic Acid has 16 carbon atoms (C16).
C16 Palmitic Acid is found especially in palm oil but also in all oils and fats of plant or animal origin (meat, butter, milk, cheese).
