If the molecular mass of an amino acid is 150 daltoms, the molecular mass of a tripeptide will beA. 450B. 486C. 504D. 414

Answer» Correct Answer - D
Tripeptide is formed by the condensation of 3 amino acids with lose of `2H_(2)O` molecules. The molecular mass of 2 water molecules is `18 xx 2 = 36`. Therefore , tripeptide mass will be `(150 xx 3) - 32 = 414`
