Answer:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
Explanation:
Amino acids are organic molecules which base chemical structure is composed by:
- a carbon atom (C)
- a carboxyl group (-COOH)
- an amino group (-NH₂)
- a side chain- called R group- which varies in different amino acids. It can be composed by N, H, O, C and sometimes S.
According to this, the five chemical elements that are present in amino acids are:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
