AMINO ACIDS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Select 2 negatively charged (acidic) R Groups.
A
Aspartate
B
Glutamine
C
Glutamate
D
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).
