b) Tripeptide | Glutathione is an important anti-oxidant in plants, animals, fungi and some bacteria. It is a tripeptide with a gamma peptide linkage between the carboxyl groups.

c) change in optical rotation | Mutarotation is the change in the optical rotation that occurs by epimerization. The optical rotation of the solution depends on the optical rotation of each anomer and their ratio in the solution.
