Question

What are tetrasaccharides? Give its general formula and an example.

Answer 1

A tetrasaccharide is a carbohydrate which gives upon hydrolysis four molecules of the same or different monosaccharides. The general formula of a tetrasaccharide is typically $C_{24}{H}_{42}{O}_{21}$.

For example, stachyose upon hydrolysis gives one molecule each of glucose and fructose and two molecules of galactose.
