Answer:
The most important nutrients (Biomolecules) found in living things are:
<u>Carbohydrates ,Proteins , Nucleic acid , lipids etc.</u>
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
