________ contain NeuNAc residues and sulfated sugars,and their negative charges contribute to the viscosity of mucins.

Question

Quizplus · Accepted Answer

NeuNAc residues and sulfated sugars are found in O-linked polysaccharides, which are a major component of mucins. These negatively charged sugars contribute to the viscous nature of mucins. Proteoglycans and N-linked polysaccharides are also involved in glycosylation, but they do not contain NeuNAc and sulfated sugars. Hyaluronic acid is a glycosaminoglycan and is not directly involved in mucin production.
