Which of the following have carbohydrate as prosthetic group?
- Glycoprotein
- Chromoprotein
- Lipoprotein
- Nucleoprotein
Answer
(1) Glycoprotein
Solution
A conjugated protein is named after its non-protein (prosthetic) group.
⇒ Glycoprotein — carbohydrate; chromoprotein — pigment (e.g. haem in haemoglobin); lipoprotein — lipid; nucleoprotein — nucleic acid.
∴ Glycoproteins have carbohydrate as the prosthetic group.
