Proteoglycans are macromolecules composed of a core protein linked to long chains of glycosaminoglycans (GAGs). Abundant in extracellular matrices, they provide structural support, regulate cell behavior, and contribute to tissue resilience. The negatively charged GAGs confer unique properties to proteoglycans, influencing their biological functions. This is an MCQ on Proteoglycans […]
