Document Summary

Chains of carbohydrate subunits also form structural molecules such as cellulose, one of they act as the major fuel substances providing chemical energy for cellular activities the primary constituents of plant cell walls. Carbohydrates get their names because they contain carbon, hydrogen, and oxygen atoms (1:2:1) Soluble in water, most have a distinctly sweet taste. One of the two forms enters much more readily into cellular reactions, just like your left hand does not fit readily into a right-hand glove, enzymes fit best to one of the two forms of an enantiomer. Alpha-glucose has the -oh group pointing below the plane of the ring. Another type of isomer is a structural isomer, which is when two molecules with the same chemical formula has atoms that are arranged in different ways, a good example of this is glucose and fructose. Bonds of this type, which commonly link monosaccharides into chains, are known as glycosidic bonds.
