Polysaccharides

In the combined state, glucose occurs in (a) Oligosaccharides (b) Polysaccharides (c ) Glycosides (d) Glycerides

Oligosaccharides.

Give differences between oligosaccharides and polysaccharides.

Classify the following carbohydrates into monosaccharide,disaccharide,oligosaccharide and polysaccharide glucose, cellulose, maltose,stachyose

Carbohydrates play a vital role in our daily life. These are classified as monosacchrides, oligosaccharides and polysaccharides depending upon the number of smaller molecules on hydrolysis. It has been suggested that monosaccharides do not have a free aldehyde or ketonic group but have cyclic hemiacetal or hemiketal structures. D - Glucose exists in two isomeric stereoisomeric forms : alpha-D- glucose and beta-D glucose which have different positions of H and OH groups on first carbon atom. Disaccharides such as sucuose, maltose, lactose, etc., give monosaccharides on hydrolysis. Polysaccharides are starch, cellulose, glycogen, having molecular formula (C_(6)H_(10)O_(5))_(n) . Name the water insoluble component of starch.
