Group 3 glycoproteins also include which additional substance alongside mucins, mucoid, and mucoprotein?

• A. Mucosubstances
• B. Lipids
• C. Nucleic acids
• D. Enzymes

Answer: (A)

Group 3 glycoproteins describe the protein components of mucus along with the carbohydrate-rich substances that accompany them. Alongside mucins, mucoid, and mucoprotein, the term mucosubstances covers the carbohydrate-containing elements of mucus, such as glycosaminoglycans, which work with the protein backbone to give mucus its gel-like, viscous properties. That combination is why mucosubstances is the best fit for the additional substance in this grouping. Lipids, nucleic acids, and enzymes are not part of this specific mucous glycoprotein categorization.
