Functions of Biomolecules

Carbohydrates provide the body with source of fuel and energy, it aids in proper functioning of our brain, heart and nervous, digestive and immune system. Deficiency of carbohydrates in the diet causes fatigue, poor mental function.
Each protein in the body has specific functions, some proteins provide structural support, help in body movement, and also defense against germs and infections. Proteins can be antibodies, hormonal, enzymes and contractile proteins.Functions of Biomolecules
Lipids, the primary purpose of lipids in body is energy storage. Structural membranes are composed of lipids which forms a barrier and controls flow of material in and out of the cell. Lipid hormones, like sterols, help in mediating communication between cells.

Nucleic Acids are the DNA and RNA, they carry genetic information in the cell. They also help in synthesis of proteins, through the process of translation and transcription.

 Structure of Biomolecules

Structure of biomolecule is intricate folded, three-dimensional structure that is formed by protein, RNA, and DNA. The structure of these molecules are in different forms, primary, secondary, tertiary and quaternary structure. The scaffold for this is provided by the hydrogen bonds within the molecule.
