Solution
The correct option is B Six
Tripeptides are amino acids polymers in which three individual amino acid units, called residues, are linked together by amide bonds.
In these, an amine group from one residue forms an amide bond with the carboxyl grop of a second residue, the amino group of the seconds forms and amide bond with the carboxyl group of the third.
Therefore, glycine, (NH2−CH2−COOH), alanine
(CH3−C|NH2H−COOH) and phenyl alanine, C6H5−CH2−C|NH2HCOOH can be linked in six different ways.
