Lipids
Lipids are very diverse in both their respective structures and functions. These diverse compounds that make up the lipid family are so grouped because they are insoluble in water. They are however soluble in other organic solvents such as ether, acetone and other lipids. Major lipid groups include fats, oils, steroids, and waxes. Lipids are made up of Hydrogen and Carbon. Glycerol makes up to monomers that make up the Lipid. The body uses Lipids to store energy and insulate the body. To store energy the body goes through the process of Dehydration, which builds up carbohydrates to store away for later. Some examples of lipids are fats, oils, and waxes. The two major ones are fats and oils.
Lipids: Fats
Fats are composed of three fatty acids and glycerol. These triglycerides can be solid or liquid at room temperature. Those that are solid are classified as fats, while those that are liquid are known as oils. Fatty acids consist of a long chain of carbons with a carboxyl group at one end. Depending on their structure, fatty acids can be saturated or unsaturated. While fats have been denigrated to the point that many believe that fat should be eliminated from the diet, fat serves many useful purposes. Fats store energy, help to insulate the body and cushion and protect organs.
