Question
Chapter 4, Problem 11P
Interpretation Introduction
To propose:
Explain the stereochemical aspects of the structure of cystine.
Introduction:
Amino acids are so named because they all are weak acids. All amino acids have at least two dissociable hydrogens, (diprotic), and some have three dissociable hydrogens and are triprotic.
