Answer: Conjugated proteins are important proteins that, upon hydrolysis, release both organic and inorganic elements as well as amino acids. The prosthetic class is the name given to the non-amino acid portion of conjugated proteins. Depending on the characteristics of their prosthetic group, conjugated proteins could perhaps be subdivided. These are
- Lipoproteins – proteins and lipid
- Phosphoproteins – proteins with a phosphoric acid group
- Metalloproteins – metal binding proteins with zinc, iron or copper
- Mucoproteins and glycoproteins – protein and carbohydrates
- Nucleoproteins – protein and nucleic acid
- Chromoproteins – proteins and a coloured pigment
