Glycosaminoglycans (GAGs) or mucopolysaccharides are long unbranched polysaccharides consisting of a repeating disaccharide unit.
- Mucopolysaccharidoses are a group of metabolic disorders in which abnormal accumulations of glycosaminoglycans occur because of enzyme deficiencies.
- Glycosaminoglycans’ primary role is to maintain and support collagen, elastin and turgidity (bounce) in the cellular spaces and keep protein fibers in balance and proportion. It also promotes the ability of the collagen and elastin fibers to retain moisture, therefore remaining soluble (Source). In skin care products, they are essential to the epidermal & dermal cells metabolism and keeping the collagen and elastin of the skin in good condition. GAGs are important in the reaction of copper peptides to help repair wrinkles and scarring. Known as the water reserve of the viable epidermis and dermis, these carbohydrates are dependent on fluid intake. Glycosaminoglycans are also linked to the lymphatic system.
