Carbohydrates are polyhydroxy aldehydes, ketones, and their derivatives composed of carbon, hydrogen, and oxygen in the ratio Cn(H2O)n. On a molecular basis, carbohydrates exist as monosaccharides, such as glucose and fructose; disaccharides, such as sucrose; and long-chained carbohydrates, the polysaccharides. Polysaccharides may be hydrolyzed yielding lower molecular weight forms. Examples of polysaccharides include pectins, glucans, and dextrans, as well as alginates used in fining. Other compounds that qualify as carbohydrates include deoxy- and amino sugars, sugar alcohols, and acids.
