Detailed explanation-1: -A lipid is a polymer composed of three fatty acid molecules and one glycerol molecule. Lipids produce a special polymer form which is considered to be a key component of cell membranes and hormones.

Detailed explanation-2: -Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic). As such, phospholipids are amphipathic.

Detailed explanation-3: -Phospholipids. Phospholipids constitute another important class of lipids. These are similar to similar to trigylcerides in that they have a glycerol backbone, but there are only two fatty acids connected to glycerol.

Detailed explanation-4: -Triacylglycerol (Triglyceride) Triacylglycerol is the major form of dietary lipid in fats and oils, whether derived from plants or animals. Triacylglycerol is composed of three fatty acids esterified to a glycerol molecule (Figure 4).
