What are carbohydrates, fats (lipids), proteins and Nucleic acids?
There are four major classes of biomolecules – carbohydrates, proteins, nucleotides (sub-units of DNA and RNA), and lipids. Carbohydrates, or saccharides, are the most abundant of the four. Carbohydrates have several roles in living organisms, including energy transportation, as well as being structural components of plants and arthropods. Carbohydrate derivates are actively involved in fertilization, immune systems, the development of disease, blood clotting and development. Carbohydrates are called carbohydrates because the carbon, oxygen and hydrogen they contain are generally in proportion to form water with the general formula Cn (H2O)n.
