Question

Quizplus · Accepted Answer

Proteoglycan tends to trap large quantities of water due to its structure, which consists of a core protein with glycosaminoglycan (GAG) chains attached. The GAG chains have many negatively charged sulfate and carboxyl groups that attract and hold onto water molecules. Collagen provides strength and structure to the matrix, hyaluronic acid helps to maintain the viscosity of the matrix, elastin allows for elasticity, and chondrocytes are the cells that produce and maintain the matrix.
