Valine. L-valine is a branched-chain amino acid (BCAA) . Other branched chain amino acids are isoleucine and leucine. Valine is an aliphatic amino acid that is closely related to leucine and isoleucine both in structure and function. Valine differs from threonine by replacement of the hydroxyl group with a methyl substituent.
Organic compound of carbon, hydrogen, and oxygen; sugars are simple carbohydrates, starches are complex carbohydrates. a compound of carbon, hydrogen and oxygen, the latter two usually in the proportions of water (CH 2 O) n. They are classified into mono-, di-, tri-, poly-and heterosaccharides. Carbohydrates in food are an important and immediate source of energy for the body; 1 gram of carbohydrate yields 3.75 calories (16 kilojoules).
