Detailed explanation-1: -Triglycerides are the main form of lipid found in the body and in the diet. Fatty acids and glycerol are the building blocks of triglycerides. Glycerol is a thick, smooth, syrupy compound that is often used in the food industry.
Detailed explanation-2: -The building blocks of lipids are one glycerol molecule and at least one fatty acid, with a maximum of three fatty acids. Glycerol is a sugar alcohol with three OH groups. It acts as a backbone for fatty acids to bond. Fatty acids are made up of a long hydrocarbon with carboxyl group, which is represented as COOH.
Detailed explanation-3: -The building block of lipids is a glycerol molecule. Glycerol is an alcohol molecule with three hydroxyl groups (-OH). These hydroxyl groups are reactive and can form ester bonds with fatty acids. When three fatty acids bond with a glycerol molecule through ester bonds, a triacylglycerol (or triglyceride) is formed.
Detailed explanation-4: -One major class of lipids is called glycerolipids. Glycerolipids are composed of glycerol and fatty acids.
