Nucleic Acids: Structure, Classification and Biological Importance

Introduction¬† Nucleic acids are the large biomolecules that store, encode and transmit genetic data from one generation to another in the form of DNA and RNA. Each functional unit of nucleic acid is called as nucleotide. Each nucleotide is made up of three parts: a phosphoric acid residue, a sugar and a nitrogen containing heterocyclic … Read more

Proteins: Classification, Structure, Chemical Nature and Biological Importance of Proteins

Introduction Proteins are complex, naturally occurring polymers of amino acids held together by peptide bonds. They are crosslinked between chains by sulfhydryl bonds, hydrogen bonds and van der wall forces. Proteins have highly complex chemical composition than any other biologically active compound. Proteins are made up of 20 alpha amino acids. Proteins comes in many … Read more

Lipids: Classification, Chemical Nature and Biological Importance

Introduction Lipids are fatty organic compounds which make up the building blocks of structure and function of cells of living organisms. Lipids are insoluble in water and soluble in nonpolar solvents. Like other biomolecules lipids also plays an important role in human life and other living organisms. Lipids serve various functions in biological systems, including … Read more

Carbohydrates: Introduction, Classification, Chemical Nature and Biological Importance

Introduction Carbohydrates or carbs are the biomolecules containing sugars, starches and fibres found in some foods. Chemically carbohydrates are polyhydroxy aldehydes or ketones, or compounds derived from their hydrolysis. Carbohydrates generally contain carbon, hydrogen and oxygen. The general formula for Carbohydrates is Cn(H2O)n. Where n is number of carbon atoms. Carbohydrates are also known as … Read more

Introduction to Biomolecules

Introduction Biomolecules plays an important role in development, support and reproduction of living organisms. The human body is composed of trillions of cells that performs the essential functions of life. To perform these functions cell takes help from several organic molecules. These organic molecules are known as biomolecules. Biomolecules presenting wide ranges of sizes and … Read more
