UKPCS Science Life Sciences-animal-bio: Biomolecules #81

Oracle IAS, the best coaching institute for UPSC/IAS/PCS preparation in Dehradun brings to you UKPCS Science Life Sciences (paper 6)- Biomolecules.

Although there is vast diversity of living organisms. The chemical compositon and metabolic reactions of the organisms appear to be similar. The composition of living tissues and non-living matter also appear to be similar in qualitative analysis.Closer analysis reveals that the relative abundance of carbon, hydrogen and oxygen is higher in living system.
All forms of life are composed of biomolecules only. These are organic molecules especially macromolecules like carbohydrates, proteins in living organisms. All living forms bacteria, algae, plant and animals are made of similar macromolecules that are responsible for life. All the carbon compounds we get from living tissues can be called biomolecules.Biomolecules

Biomolecules Definition:

Biomolecules are molecules that occur naturally in living organisms. These include macro-molecules like proteins, carbohydrates, lipids and nucleic acids. It also includes small molecules like primary and secondary metabolites and natural products. They consists mainly of carbon and hydrogen with nitrogen, oxygen, sulphur, and phosphorus. They are very large molecules of many atoms, that are covalently bound together.
