Trivia Quiz On Lipids Or Fats In Biochemistry

Let’s start the quiz

Fats or lipids are long-chain fatty acids and alcohol esters. These are waxy or oily substances present in all organisms. These are non-hydrophilic and hydrophobic compounds. These are soluble in organic solvents such as chloroform, benzene, ether while insoluble in water. All lipids are made by carbon {C}, hydrogen {H} and oxygen {O}. Phosphorus {P}, nitrogen {N} and sulfur {S} are also present in some lipids. Lipids do not form polymers like proteins and carbohydrates. Neither are they considered large molecules. Lipids play an important role in living organisms. Some of their main functions include energy storage, hormones, and cell membranes. Let's know more about Fats or lipids.
