Question

Write one example of monosaccharide carbohydrate?

Answer 1

First, we must know what a monosaccharide and a carbohydrate is. A monosaccharide is said to be the most basic form of carbohydrates and they possess one sugar unit that cannot be further broken down. They produce and also store energy and have a general formula of ${(C{H_2}O)_n}$. Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products.

Complete answer:
One example of a monosaccharide carbohydrate is Glucose which is of the molecular formula ${C_6}{H_{12}}{O_6}$. It contains an aldehyde group hence it is also called as aldohexose. It is also the most abundant monosaccharide carbohydrate. Glucose is usually present in solid state as a monohydrate with a closed pyran ring. Whereas in aqueous solution, it is an open-chain to a small extent and is present predominantly as α- or β-pyranose. From aqueous solutions, the three known forms can be crystallized: α-glucopyranose, β-glucopyranose and β-glucopyranose hydrate. Glucose is a building block of the disaccharides lactose and sucrose

Additional information:
Most of the carbohydrates are polymers. Polymers are said to be large, complex molecules composed of long chains of monomers. Monomers are small, basic molecular units. Carbohydrates can be divided into three different classes based on the number of sugar units they possess: monosaccharides, disaccharides, and polysaccharides.

Note: Carbohydrates are the molecules that contains carbon, hydrogen, and oxygen. There are always twice as many hydrogen atoms as carbon or oxygen atoms and they act as the source of energy an example is glucose, as a store of energy which is starch and glycogen and as structural units like cellulose in plants and chitins in insects.
