Amino acids are organic compounds that contain amine (−NH2) and carboxyl (−COOH) functional groups, along with a side chain (R group) specific to each amino acid. a-carbon of cc-amino acid is asymmetric. Hence this statement is true. Proteins exist in both D and L -form. Human body can synthesize all proteins they need. At pH=7, both amino and carboxylic groups exist in ionised form.
