Identify a side chain (R) group present in Leucine, an amino acid.
Options
- AH -
- B- CH ₃
- CMe ₂ CH -
- DMe ₂ CH - CH ₂-
Correct answer
D. Me ₂ CH - CH ₂-
Step-by-step solution
The side chain (R group) of leucine is an isobutyl group with structural formula Me ₂ CH - CH ₂- . Comparing the options: A) H - (glycine) B) - CH ₃ (alanine) C) Me ₂ CH - (valine) D) Me ₂ CH - CH ₂- (leucine) The isobutyl group corresponds to option D.
