Glossary Proteoglycans

large molecules with protein cores and sugar chains

Proteoglycans are large molecules found in the body that consist of a core protein attached to long chains of sugars called glycosaminoglycans (GAGs). They play a crucial role in maintaining the structure and function of tissues, including the skin and hair, by providing hydration and resilience. In the context of hair, proteoglycans are important for the growth cycle and health of hair follicles.
