Detailed explanation-1: -A fat molecule consists of two kinds of parts: a glycerol backbone and three fatty acid tails. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.
Detailed explanation-2: -One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids.
Detailed explanation-3: -Phospholipids are molecules that form the cell membrane. They consist of a polar phosphate head group and two nonpolar fatty acid tails joined by a glycerol backbone.
Detailed explanation-4: -1: A phospholipid consists of a head and a tail. The “head” of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.
