- What distinguishes the routes by which each of the following
amino acids appears in human proteins?
- 5-hydroxylysine
- g-carboxyglutamate
- Selenocysteine
Homework Answers
Answer
The correct answer is - R - group.
The R-group distinguishes the routes by which each of the following amino acids appears in human proteins. The amino acids are classified on the basis of the R group attached to it. It also plays a role in protein interactions.
