Collagen is a conjugated protein. Its non-protein part contains:   1 point- Heme- Phosphoric acid residue- Metal ions-Glucose

Collagen is a type of protein that is abundant in the human body. It is not a conjugated protein, but a fibrous protein. Conjugated proteins are proteins that function in interaction with other chemical groups attached by covalent or noncovalent bonds.

However, to answer your question, the non-protein part of collagen does not contain heme, phosphoric acid residue, metal ions, or glucose. Collagen is made up of amino acids wound together to form triple-helices to form of elongated fibrils. It is rich in amino acids like proline and glycine.

So, none of the options you provided are correct.
