The question:
Which peak(s) in Figure 1 correspond to amino acids that have primary alcohols in their side chains?
A. Peak 2 only
B. Peak 3 only
C. Peaks 2 and 3 only
D. Peaks 2, 3, and 15 only
Peaks:
Peak 2 corresponds to Threonine
Peak 3 corresponds to Serine
Peak 15 corresponds to Tyrosine
Rationale:
All three amino acids have an alcohol group present in their side chains. However, only Serine has a primary alcohol in its R-group, which is why I tagged these cards. It is important to recognize the structure of Serine and understand what defines a primary alcohol.
