Carbohydrates, often perceived merely as a source of energy, actually hold a far more vital function in biology. A significant percentage of all carbohydrates on Earth are structural, demonstrating that carbohydrates have a crucial structural role in eukaryotic cells, forming complex architectures essential for life.

Proteoglycans are a crucial component of the extracellular matrix (ECM) in connective tissues, comprising up to 95% of the ECM's weight. Understanding their structure and categorization is key to appreciating their diverse functions in the body, from structural support to cellular signaling. This article delves into the primary classification methods and significant types of these heavily glycosylated proteins.

Cartilage, a resilient and flexible connective tissue, is often misunderstood regarding its basic composition. While it is not a direct source of dietary carbohydrates, a significant portion of its structure is built from complex carbohydrate molecules that play a vital role in its function.

Over half of the body's total hyaluronic acid, a key component of proteoglycans, is located in the skin. These complex molecules are essential for the hydration, elasticity, and resilience of both skin and cartilage. Boosting your body's proteoglycan levels can significantly improve joint function and combat the visible signs of aging.

Approximately 95% of a proteoglycan’s structure is made of glycosaminoglycan (GAG) chains, giving these molecules their unique hydrating gel-like properties in connective tissues like cartilage and skin. Finding what foods contain proteoglycans or their components can be key to maintaining robust connective tissue and skin health.

Cartilage is a strong, flexible connective tissue that cushions your joints and bones, and a key component of its structure is protein. Specifically, its extracellular matrix is rich in both fibrous proteins like collagen and heavily glycosylated proteins called proteoglycans.

Up to 80% of cartilage by weight is actually water, not fat or protein, though protein is the main solid component. This critical tissue's function relies on a complex mix of specialized cells and a protein-rich extracellular matrix, providing flexibility and support throughout the body.

Comprising up to 80% water, cartilage is a resilient connective tissue rich in a specialized extracellular matrix. Knowing what is cartilage rich in helps to understand its unique properties and how it functions as a shock absorber and low-friction surface for joints.

Over half of a tendon's wet mass is composed of water, with the dry weight being dominated by a key structural protein. Tendons, the tough bands of fibrous connective tissue connecting muscle to bone, are rich in collagen, water, and a host of other crucial components that provide both high tensile strength and viscoelastic properties.
