Lipids are important biomolecules. A typical lipid contains a glycerol, fatty acid chains and a functional group in its structure.
Glycerol is a molecule made up of three carbon atoms. Glycerol forms the backbone in the structure of lipids.
Unsaturated fatty acids contain a single bond in its structure while the saturated fatty acids contain double bonds.
Unsaturated fatty acids have a straight chains while saturated fatty acids are bent.
Glycerol and threefatty acids together make up one triglyceride molecule.
Triglycerides are primarily found in blood and also present in the adipose tissues.
Lipids form an integral part of the cell membrane and also present around the organs creating cushion.
Therefore, lipids are important biomolecules for energy conservation and in the body.
