The component of basement membranes that is usually demonstrated with special stains is?

Explanation:
Basement membranes glow with carbohydrates because they are rich in carbohydrate-containing molecules like glycoproteins and proteoglycans with glycosaminoglycan chains. These carbohydrate components are what histochemical stains are designed to pick up, especially the periodic acid–Schiff (PAS) reaction, which highlights carbohydrates by producing a magenta color. So, among the options, the carbohydrate portion is what is routinely demonstrated in basement membranes. Lipids, nucleic acids, and most proteins aren’t highlighted as distinctly by these standard basement membrane stains.
