Select 2 negatively charged (acidic) R Groups.
|
Aspartate
|
|
Glutamine
|
|
Glutamate
|
|
Glycine
|
Explanation:
Detailed explanation-1: -Glutamate is an acidic amino acid. At a pH below 2.2 (acidic conditions), the side chain, the amino group, and the carboxyl backbone would all be protonated (+1 net charge).
Detailed explanation-2: -Substitutions: Glutamate (or Glutamic acid) is a negatively charged, polar amino acid.
Detailed explanation-3: -Negatively charged polar R-groups Both aspartic acid and glutamic acid contain a second carboxyl group that is negatively charged at a physiological pH (the acidity of most bodily fluids varies between 6.5 and 8.0).
