DESCRIPTION
Alpha-Carotene is a fat-soluble carotenoid that imparts a bright orange-yellow color and is most abundantly found in carrots, pumpkins, and sweet potatoes.
It is an isomer of beta-carotene, with both molecules containing 40 carbon atoms arranged in a long, conjugated polyene chain.
Alpha-Carotene is less abundant in the human diet than beta-carotene but exhibits strong antioxidant activity and potential health benefits.
Alpha-Carotene is a naturally occurring carotenoid with the chemical formula C40H56.
Alpha-Carotene is a provitamin A compound, convertible to retinol in the human body.
Alpha-Carotene has two ring structures: one beta-ring and one epsilon-ring.
Alpha-Carotene is found in orange and yellow vegetables such as carrots, pumpkins, and sweet potatoes.
Alpha-Carotene has been linked to reduced risk of chronic diseases, such as heart disease and certain cancers, when consumed through fruits and vegetables.
In the human body, alpha-carotene is metabolized into retinoids that support vision, skin health, immune function, and embryonic development.
Alpha-Carotene is naturally sourced and generally regarded as safe, biodegradable, and biocompatible.
Its stability is influenced by factors such as heat, light, oxygen, and pH, and therefore must be protected during processing and storage.
Alpha-Carotene is used in oil-based systems and emulsions due to its lipid solubility.
Alpha-Carotene is non-toxic, non-carcinogenic, and used widely in clean-label and natural product formulations.
