Detailed explanation-1: -Lecithin is a component of cell membrane and are mixtures of Glycerophospholipids including phosphatidylcholine, Phosphatidylethanolamine, phophosphatidylinositol, Phosphatidylserine, Phosphatidic acid So, the correct answer is ‘Lecithin-a component of cell membrane’
Detailed explanation-2: -Lipids are organic molecules composed of carbon, hydrogen, and oxygen atoms. The ratio of hydrogen atoms to oxygen atoms is much higher in lipids than in carbohydrates. Lipids include steroids (the material of which many hormones are composed), waxes, and fats.
Detailed explanation-3: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).
Detailed explanation-4: -The four main organic compounds that make up living things are carbohydrates, lipids, nucleic acids, and . Lipids are one of four classes of biochemical compounds, which are compounds that make up living things and carry out life processes.
Detailed explanation-5: -Which organic molecule is paired with its function? carbohydrate : to provide quick-release energy.
