Explain about the Glycoproteins?
Most of the naturally occurring conjugated proteins are glycoproteins. Sugar molecules are covalently bound to them, especially those secreted from the cell. They range in size from a molecular weight of 15,000 to more than one million. The carbohydrate component varies from 1 to 85%. Glycoproteins with more than 80% of their molecules as carbohydrates are called 'proteoglycans.'
