An essential amino acid, C4H9CH(NH2)COOH, gotten because of the hydrolysis of necessary protein by pancreatic enzymes during food digestion and essential for ideal growth in babies and children and for the upkeep of nitrogen balance in grownups.
a vital amino acid, C6H13NO2, isomeric with isoleucine, within most animal proteins; it is crucial for growth in kiddies.
a naturally happening alpha-amino acid ((CH3)2CH.CH2.CH(NH2)-COOH), one of several building devices of virtually all proteins of living organisms, both pet and veggie. It's one of many essential amino acids (perhaps not synthesized because of the human anatomy, a required component for correct nourishment), and is hydrophobic in character when bound in proteins. In isolated kind it really is a white, crystalline, zwitterionic material formed, age. g. because of the decomposition of proteins by pancreatic digestion, because of the activity of boiling dilute mineral acid, or by putrefaction. Chemically it is to be regarded as amido-caproic acid. It happens as two optical isomers, the L- and D-forms. The L-form, L-leucine, is the normal form, contained in many proteins.
a white crystalline amino acid occurring in proteins that's needed for nutrition; acquired because of the hydrolysis on most dietary proteins
