Chapter 15, Problem 15.94P
(a)
Interpretation Introduction
Interpretation:
The R group of Glycine has to be drawn.
Concept Introduction:
In amino acids R group is the substituent group. If the substituent group contains a carboxylic group, the amino acid is acidic and if the substituent group contains an amino group, the amino acid is basic. If it contains an alkyl group, it is neutral amino acid.
(b)
Interpretation Introduction
Interpretation:
The R group of Isoleucine has to be drawn.
Concept Introduction:
In amino acids R group is the substituent group. If the substituent group contains a carboxylic group, the amino acid is acidic and if the substituent group contains an amino group, the amino acid is basic. If it contains an alkyl group, it is neutral amino acid.
(c)
