Aggrecan

Aggrecan is a key protein found in cartilage, the flexible tissue that cushions joints. It acts like a sponge by attracting and holding water, giving cartilage its resilience and ability to absorb impact. Aggrecan also provides structural support, helping cartilage withstand stress and maintain its shape. Its presence and function are essential for healthy joint movement and comfort. When aggrecan breaks down or decreases, cartilage can weaken, leading to joint problems like osteoarthritis. Overall, aggrecan is a vital component that maintains the strength, flexibility, and cushioning properties of cartilage.
