The most important nutrients (Biomolecules) found in living things are:

Carbohydrates ,Proteins , Nucleic acid , lipids etc.

Explanation:

1. Carbohydrates :

Some common examples of carbohydrates are : Sugar . Glucose , starch etc.

They are defined as optically active polyhydroxy aldehyde or ketones. They are classified into three main categories:

a). Monosaccharide : These are smallest carbohydrates which can not be hydrolysed .Example : Glucose

b) Oligosaccharide : Examples of such carbohydrates are  mannose and sucrose

c). Polysaccharide : examples of such carbohydrates are : Starch , cellulose

2. Proteins : The chief source of protein are : milk , cheese , pulses,peanut etc

They occur in every part of the body and very necessary for the life processes.

Proteins are the polymers of amino acids.

There are two types of amino-acid :

Essential amino acid : Those amino acids which are not synthesized by the body but must be required by the body . example : Histidine

Non - essential : Which are synthesized by the body. example :Serine

3. Nucleic Acid : Nucleic acid are responsible for transfer of character from parents to off-springs. There are two type of nucleic acid :

DNA = Deoxy ribo nucleic acid

RNA = Ribo nucleic acid
