Question

what element do amino acids have that carbohydrates and lipids do not have? 1 point oxygen phosphorus nitrogen

Explanation:

Amino acids are the building blocks of proteins. The general formula of an amino acid includes an amino group ($-NH_2$) which contains nitrogen. Carbohydrates are made of carbon, hydrogen, and oxygen (e.g., $C_n(H_2O)_m$), and most lipids are primarily composed of carbon, hydrogen, and oxygen (some phospholipids have phosphorus, but typical lipids and carbohydrates lack nitrogen). So amino acids have nitrogen which carbohydrates and lipids (usually) do not.

Answer:

Nitrogen
