| L+Lactic Acid, Calcium Salt, Hydrate | Lactic acid (2-hydroxypropanoic acid), also known as milk acid, is a chemical compound that plays a role in several biochemical processes. It was first isolated in 1780 by a Swedish chemist, Carl Wilhelm Scheele, and is a carboxylic acid with a chemical formula of C3H6O3. It has a hydroxyl group adjacent to the carboxyl group, making it an alpha hydroxy acid (AHA). In solution, it can lose a proton from the acidic group, producing the lactate ion CH3CH(OH)COO?. It is miscible with water or ethanol, and is hygroscopic. Lactic acid is chiral and has two optical isomers. One is known as L-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is D-(-)-lactic acid or (R)-lactic acid. L-(+)-Lactic acid is the biologically important isomer.

| Lycopene, 90% | Lycopene is a phytochemical, synthesized by plants and microorganisms but not by animals. It is an acyclic isomer of beta-carotene. This highly unsaturated hydrocarbon contains 11 conjugated and 2 unconjugated double bonds, making it longer than any other carotenoid. As a polyene, it undergoes cis-trans isomerization induced by light, thermal energy, and chemical reactions. Lycopene obtained from plants tends to exist in an all-trans configuration, the most thermodynamically stable form. Humans cannot produce lycopene and must ingest fruits, absorb the lycopene, and process it for use in the body. In human plasma, lycopene is present as an isomeric mixture, with 50% as cis isomers. Group: Biochemicals. Alternative Names: ?,?-Carotene; all-trans-Lycopene; C.I. 75125; Lyco Vit; Lycopene 7; Lycored; NSC 407322; Redivivo; all-trans-Lycopene; trans-Lycopene. Grades: Highly Purified.
