What elements make sucrose? What elements make a fat molecule? What elements make amino acids?

Answer 1

Carbon, hydrogen, and oxygen make up sucrose.

Fat CAN contain nitrogen, phosphorus, etc, but normally, a triacyl glyceride (fat) is composed of only carbon, hydrogen, and oxygen.

Amino acids contain carbon, hydrogen, oxygen, and nitrogen. Two amino acids also contain sulfur (cysteine and methionine).
