Concept explainers
Interpretation:
The structures of amino acids that are formed by the hydrolysis of ester and amide linkage of aspartame molecule should be determined and the amino acid with carbonyl group and the nitrogen atom of the amide bond should be identified.
Concept Introduction:
Proteins are
These amino acids involve in condensation process to form peptides and polypeptides which further form complex protein molecules. Amino acids are the organic molecules with both
