β-Carotene (Provitamin A) is a naturally-occurring retinol (vitamin A) precursor obtained from certain fruits and vegetables with potential antineoplastic and chemopreventive activities. As an anti-oxidant, beta carotene inhibits free-radical damage to DNA.

Astaxanthin (trans-Astaxanthin) is a keto-carotenoid in the terpenes class of chemical compounds. It is classified as a xanthophyll but it is a carotenoid with no vitamin A activity. It is present in most red-colored aquatic organisms. Astaxanthin has shown to mediate anti-oxidant and anti-inflammatory actions. It may be found in fish feed or some animal food as a color additive.

9-cis-β-Carotene, a precursor of retinal, is cleaved by beta-carotene oxygenase 1 (BCMO1) to produce 9-cis-retinal, which inhibits photoreceptor degeneration and restores retinal function in vivo.

Retinyl acetate (Vitamin A acetate) is a group of unsaturated nutritional hydrocarbons, that contains retinal, retinol, retinoic acid, and several provitamins A carotenoids, among which beta-carotene is the most important.

Ketoisophorone (2,6,6-Trimethyl-2-cyclohexene-1,4-dione) is the major ingredients of saffron spice. It is a cyclic olefin and was reported as a product of the thermal degradation of β-carotene in aqueous suspension.

Lycopene (ψ,ψ-Carotene) is a linear, unsaturated hydrocarbon carotenoid, the major red pigment in fruits such as tomatoes, pink grapefruit, apricots, red oranges, watermelon, rosehips, and guava. As a class, carotenoids are pigment compounds found in photosynthetic organisms (plants, algae, and some types of fungus), and are chemically characterized by a large polyene chain containing 35-40 carbon atoms; some carotenoid polyene chains are terminated by two 6-carbon rings. In animals, carotenoids such as lycopene may possess antioxidant properties which may retard aging and many degenerative diseases. As an essential nutrient, lycopene is required in the animal diet.

Dihydro-β-erythroidine hydrobromide(DHβE) is a potent, oral active and competitive antagonist of neuronal nicotinic acetylcholine receptors (nAChRs). Dihydro-β-carotene hydrobromide showed selectivity to α4β4 and α4β2nAChR, with IC50 of 0.19 and 0.37 μM,

β-Carotene-13C10 (Provitamin A-13C10) is a form of β-Carotene labeled with 13C. It is a carotenoid compound and serves as a natural precursor to vitamin A. This compound acts as a regulator of reactive oxygen species (ROS), exhibiting both antioxidant and anti-inflammatory properties. Depending on its intrinsic characteristics and the redox potential of the biological environment, β-Carotene can function either as an antioxidant or a pro-oxidant. It also possesses anticancer activity, inducing apoptosis in breast cancer cells.

9(Z),11(E)-Conjugated linoleic acid is an isomer of linoleic acid that has been found in beef and milk fat.1It binds to peroxisome proliferator-activated receptor α (PPARα; IC50= 140 nM) and activates the receptor in a reporter assay using COS-1 cells expressing mouse PPARα when used at a concentration of 100 μM.29(Z),11(E)-Conjugated linoleic acid inhibits TNF-α-inducedGLUT4expression and increases insulin-stimulated glucose transport in 3T3-L1 adipocytes.3Dietary administration of 9(Z)11(E)-conjugated linoleic acid reduces serum fasting glucose, insulin, and triglyceride levels and decreases white adipose tissue macrophage infiltration inob/obmice. It also increases body weight gain and body fat in weanling mice.4[Matreya, LLC.
