Glycosaminoglycan is best described as what?

Glycosaminoglycan is best described as what?

• A. Water-binding substance between the fibers of the dermis
• B. A mineral
• C. A protein
• D. An enzyme

Answer: (A)

Glycosaminoglycans are long carbohydrate chains that are key parts of the extracellular matrix in connective tissue. They are highly hydrophilic and carry negative charges, which makes them attract and hold water. This creates a hydrated gel that sits between collagen fibers in the dermis, helping to keep skin hydrated, resilient, and able to resist compression. They are not minerals, proteins, or enzymes; they are carbohydrate polymers that provide the water-binding property in the dermal matrix.
