(a)
Interpretation:
The structures of amino acid which are formed by the hydrolysis of a given tripeptide molecule should be drawn.
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
(b)
Interpretation:
The structures of amino acid which are formed by the hydrolysis of given tripeptide molecule should be drawn.
Concept Introduction:
Proteins are biomolecules that are composed of certain monomer units such as amino acids. These are carboxylic acids with one amino group bonded on the alpha-C atom of the molecule.
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
