Question

Why-lysine-threonine-proline-does-not-undergo-transamination?

Answer 1

Answer:

Because for two substances to undergo a transamination reaction one must be an alpha amino acid, which lysine is (it also contains a free amino group in its side chain). ... Proline is not an alpha keto acid, it is an amino acid which comprises its alpha amino group in a cyclic form (it is a pyrrolidine ring).

Answer 2

Explanation:

for an amino acid that has to be transaminated it must have an alpha amino group that would be converted to an alpha keto acid,so in the case of proline it has a pyrrolidine ring and the alpha amino group is abscent so it can't be transaminated.
