Question

What is oligosaccharide?

Answer 1

Hint: Oligosaccharides are the carbohydrates whose molecule on hydrolysis yields two to ten monosaccharides units . they are covalently bonded to each other by glycosidic bonds.

Complete step by step answer:
Oligosaccharides have been prepared by partial breaking down more complex carbohydrates (polysaccharides). Oligosaccharide is a saccharide polymer containing. These are the carbohydrates which are optically active polyhydroxy aldehydes or poly ketones or the compounds which produce such compounds on hydrolysis. The carbohydrates are classified into monosaccharide, oligosaccharides, and polysaccharides. Monosaccharides Are the simplest carbohydrates which cannot be hydrolysed into simpler compounds. Examples of monosaccharide are glucose and fructose. Oligosaccharide are the carbohydrates which give two to ten monosaccharides unit on hydrolysis. Example of oligosaccharide is cane sugar. Polysaccharides are the carbohydrates which are polymeric and can be hydrolysed to give large numbers of monosaccharide units. Examples of polysaccharides are cane sugar.

\[{{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}+n{{H}_{2}}O\to n{{C}_{6}}{{H}_{12}}{{O}_{6}}\]

These are the carbohydrates which give two to ten small numbers of monosaccharide units on hydrolysis. The example of oligosaccharide is cane sugar.

\[{{C}_{12}}{{H}_{22}}{{O}_{11}}+{{H}_{2}}O\to
{{C}_{6}}{{H}_{12}}{{O}_{6}}+{{C}_{6}}{{H}_{12}}{{O}_{6}}\]
$\text{(Cane sugar) (Fructose) (Glucose)}$

Note: most naturally occurring polysaccharide are found in plants. Oligosaccharides have many functions including cell recognition and cell binding. Saccharide has another name used for the sugar - and an oligosaccharide mainly refers to the carbohydrate polymer whose molecules are composed of a relatively small number of monosaccharide units.
