Nglicanos

Nglicanos is a term that refers to a class of complex carbohydrates, also known as glycosaminoglycans or GAGs. These are long, unbranched polysaccharides consisting of repeating disaccharide units. The disaccharides typically comprise a hexosamine (either glucosamine or galactosamine) and a uronic acid (either glucuronic acid or iduronic acid), though some exceptions exist. A characteristic feature of nglicanos is the presence of sulfate groups attached to the sugar residues, which contributes significantly to their overall negative charge and highly hydrated nature.

These molecules play crucial roles in various biological processes. They are major components of the extracellular matrix, providing structural support and lubrication to connective tissues, cartilage, and skin. Their negative charges attract water molecules, forming a gel-like substance that resists compression and allows tissues to withstand mechanical stress. Nglicanos are also involved in cell signaling, cell adhesion, and wound healing. Different types of nglicanos, such as hyaluronic acid, chondroitin sulfate, dermatan sulfate, keratan sulfate, and heparin/heparan sulfate, have distinct structures and perform specific functions within the body. For instance, hyaluronic acid is abundant in synovial fluid and the vitreous humor of the eye, while heparin is a potent anticoagulant.
