Describe the composition of common amino acids.

Explanation:

Amino acids consist of an amine (-NH2) group and a carboxyl acid (-COOH) group. So they have elements such as Nitrogen (N), Hydrogen (H), Carbon (C) and Oxygen (O).

Amino acid composition:

The human body has 20 amino acids which are all important but there are only 9 that are essential for the human body.

Best of Luck!

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
