Chemistry - Biomolecules Question with Solution | TestHub

Amino acids are classified as acidic, basic or neutral depending upon the relative number of amino and carboxyl groups in their molecule. The amino acids, which can be synthesised in the body, are known as non essential amino acids. On the other hand, those which cannot be synthesised in the body and must be obtained through diet, are known as essential amino acids. The pH at which the amino acid shows no tendency to migrate when placed in and electric field is known as iso-electric point (pI).
