They are classified as macromolecules and micro molecules.
Four major types of biomolecules are carbohydrates, proteins, lipids, and nucleic acids.
Importance:
They are important for the maintenance and metabolic process of the cell.
Biomolecules are important for the proper functioning of the body.
Carbohydrates:
Carbohydrates are biomolecules composed of carbon, hydrogen, and oxygen atoms.
Carbohydrates are obtained from various sources such as bread, milk, potatoes, cookies, corn, etc.
There are two types of carbohydrates: Simple and complex.
The three types of simple carbohydrates include: Monosaccharides - Eg: Glucose, galactose, and fructose, Disaccharides - Eg: lactose, maltose, sucrose, Polysaccharides - Eg: starch and glycogen.
Complex carbohydrates are sugars in which sugar molecules are linked together into long, complex chains.
Functions of carbohydrates include providing energy and regulates blood sugar, limiting the use of protein for energy.
Nucleic acids:
Nucleic acids are large biological molecules that are essential to all cells and viruses.
Nucleic acids, deoxyribonucleic acid (DNA), and ribonucleic acid (RNA) carry genetic information that is read in cells to make RNA and proteins on which living organisms function.
The well-known structure of the DNA double helix makes it possible to copy this information and pass it on to the next generation.
The three main functions of nucleic acids are gene expression and regulation of cellular activities, storage, and transmission of genetic information.
Proteins:
Proteins are responsible for almost every venture of cell life, along with cellular form and internal organization, product manufacture and waste cleanup, and recurring maintenance.
Proteins additionally acquire indicators from out of doors the cellular and mobilize an intracellular response.
Functions of proteins include: Growth, maintenance, provide structure, maintain proper pH balance, fluid transport and stores nutrients.
Lipids:
Lipids are organic compounds that are non-polar molecules, soluble only in non-polar solvents and insoluble in water because water is a polar molecule.
Lipids can be synthesized in the liver and are found in oils, butter, whole milk, cheese, fried foods, and also in some red meats.
Functions of lipids include: Storing energy, signaling and acting as structural components of cell membranes, regulate hormones, protect vital organs.
