Helps in providing cellular structure and promotes cellular functions, that is why it’s also known to be building blocks of life. Carbohydrates provide adequate amount energy for all organisms. They form the key part of cellular wall in plants and fungi. Lipids found in the human body are phospholipids, cholesterol and sphingolipids. Cellular membrane contains lipids. Nucleic acids are combination of five carbon containing sugar, nitrogenous base and a phosphate group. DNA (deoxyribonucleic acid) is the major element in the genetic material of all cells.
