Answer :
Glu ang gin are two amino acids are key to the transfers of amino groups during breakdown and synthesis of amino acids.
What are amino acids?
Amino acids are chemical molecules containing side chains unique to each amino acid as well as amino and carboxylic acid (CO2H) functional groups. Every amino acid contains the elements carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) (CHON); in addition, the side chains of cysteine and methionine contain sulfur (S), while the less frequent amino acid selenocysteine has selenium (Se). As of 2020, more than 500 naturally occurring amino acids have been identified as the building blocks of peptides and proteins, but only 22 of them are represented in the genetic code, 20 of which have unique designated codons, and two of which—selenocysteine, which is found in all eukaryotes, and pyrolysine, which is found in some prokaryotes—have unique coding mechanisms.
