Storage substance

It has been estimated that >90% of the carbohydrate mass in nature is in the form of polysaccharides. In living organisms, carbohydrates play important roles. In terms of mass, the greatest amounts by far are stmctural components and food reserve materials, in that order and both in plants. However, carbohydrate molecules also serve as stmctural and energy storage substances in animals and serve a variety of other essential roles in both plants and animals.

Liver cells also take up glucose from the blood but this process is not dependent on insulin. In muscle and the liver, insulin also promotes the conversion of glucose to glycogen, a starch-like storage substance for carbohydrates. 

The polysaccharide inulin is an energy-storage substance found in the tubers of a number of plants.

PolyCjS-hydroxyalkanoates) [poly(/3-hydroxyalkan-oic acids) PH A, PH A A]. Numerous bacteria form poly(/S-hydroxyalkanoates) (PHA) as reserve or storage substances that can serve as sources of carbon and energy when required. Monomeric components of the PHA include /5-hydroxybutyric acid, jS-hydroxyvaleric acid, and lactic acid. The linear polymer poly(jS-hy-droxybutyric acid) (PHB, PHBA) is accumulated intra-cellularly in the form of grains or granules and is one of the more important PHAA. As the polyester it is soluble in chloroform, insoluble in ether and consists on average of 60 (max. 25 000) hydroxybutyric acid units. 

Poly(3-hydroxybutyxate) is a thermoplastic polymer which is accumulated as an energy storage substance within the cells of many microorganisms and shows excellent biodegradability and biocompatibility. Therefore it is of interest for plastics for preserving environments (16).
