Question

What are the building blocks of carbohydrates?

Answer 1

Hint: Carbohydrates are essential to the human body and consists mainly of carbon, hydrogen and oxygen atoms. The hydrogen atoms in the carbohydrates are double to the oxygen atoms. These compounds are mainly sugars and formed by the combination of monosaccharides units.

Complete answer:
Human body requires certain nutrients or substances in order for the normal growth of the body. These substances include carbohydrates, proteins and fats. The carbohydrates are the molecules consisting of carbon, hydrogen and oxygen atoms. The hydrogen atoms in the carbohydrates are double to the oxygen atoms. The general molecular formula of the carbohydrates are $$C_x{\left(H_{2}O\right)}_y$$, where x is number of carbon atoms and y is number of number of hydrogen and oxygen atoms.
Simply carbohydrates can be called hydrates of carbon.
Carbohydrates are mainly sugar molecules. These are classified into three types. Based on the monomer units these were classified into three types. They are monosaccharides, oligosaccharides and polysaccharides.
The monosaccharides are the simplest units of carbohydrates. Oligosaccharides are carbohydrates that have the monomer units from two to ten. The carbohydrates with monomer units more than ten are called polysaccharides.
Thus, monosaccharides are the building blocks of carbohydrates.

Note:
Glucose, fructose and galactose are examples of monosaccharides. These have the molecular formula of $$C_6{H}_{12}{O}_6$$ . Sucrose has the molecular formula of $$C_{11}{H}_{22}{O}_{12}$$, it is an example of disaccharide and comes under oligosaccharides. Cellulose is an example of polysaccharide and has a number of monomers.
