Question

A polypeptide with a net positive charge at physiologic ph (~7.4) most likely contains amino acids with r groups of what type

Answer 1

Answer:

basic amino acid

Explanation:

Nothing

Answer 2

Basic amino acids are polypeptides with a net positive charge at physiologic ph (~7.4).

• Basic amino acids possess a net positive charge at physiological pH at 7.4

• Basic amino acids have an extra amino group in the side chain that can release H+ ions into the medium resulting in the formation of NH₃+

• Similarly, acidic amino acids have an extra amino group in the side chain that can lose H+ ions into the medium resulting in the formation of COO-
