most important components of the extracellular matrix. Hyaluronic acid‚ condroitin sulfates and dermatan sulfates are important heteropolysaccharides in the extracellular matrix. These heteropolysaccharides usually are formed by the repetition of a disaccharide unit of an aminosugar and an acid sugar. A typical example Other common constituents are sulfate groups linked to certain monosaccharides. Usually heteropolysaccharides are associated with proteins forming proteoglycans‚ glycosaminoglycans

hexose (Mader‚ 2010). Ribose and deoxyribose‚ both with five carbon atoms‚ are pentoses and are also found in RNA and DNA. A disaccharide contains two monosaccharides that have joined together during a dehydration reaction. Sucrose is a disaccharide of distinction because it’s the basic sugar we use at home as table sugar (Mader‚ 2010). Lactose is the disaccharide found in milk and dairy products. Polysaccharides are polymers of monosaccharides. Some of these function as short term energy

Amylase in an enzyme that breaks down starch by breaking the long chains of polysaccharides into disaccharides‚ which is converted into glucose. In the human body there are several main sources of carbohydrates. Which are sucrose ( cane sugar) lactose (a disaccharide in milk) starches (present in all almost non animal foods these are large polysaccharides and found in particular grains there is also fructose (a monosaccharide) (Better
