Multiple choice

Which glycoconjugate can have more than one oligosaccharide chain along with covalent linkage with the polypeptide backbone?

Glycoconjugate molecules are biologically active. They are formed as a result of the covalent bonding of oligosaccharides and polysaccharides with lipid or protein molecules.

  1. Proteoglycan

  2. Peptidoglycan

  3. Glycoprotein

  4. Ganglioside

  5. None of these

C Correct answer
Explanation

The proteins having one or more oligosaccharide chains bound covalently to side-chains of polypeptides are called glycoproteins. Glycoproteins like TSH, HCG, FSH, etc., act as hormones. Other glycoproteins include transferrin, immunoglobin, lectin, calnexin, etc.
