Cholesterol is a sterol, a steroid-like lipid made by animals, including humans.The human body makes one-eighth to one-fourth teaspoons of pure cholesterol daily. A cholesterol level of 5.5 millimoles per litre or below is recommended for an adult.

Lipid numbers 18:3 18:3n3 18:3, cis,cis,cis-Δ 9,Δ 12,Δ 15 18:3(9,12,15) Lipid numbers take the form C:D, [a] where C is the number of carbon atoms in the fatty acid and D is the number of double bonds in the fatty acid. If D is more than one, the double bonds are assumed to be interrupted by CH
Food is mainly composed of water, lipids, proteins, and carbohydrates. Minerals (e.g., salts) and organic substances (e.g., vitamins ) can also be found in food. [ 4 ] Plants, algae , and some microorganisms use photosynthesis to make some of their own nutrients. [ 5 ]
A saturated fat is a type of fat in which the fatty acid chains have all single bonds between the carbon atoms. A fat known as a glyceride is made of two kinds of smaller molecules: a short glycerol backbone and fatty acids that each contain a long linear or branched chain of carbon (C) atoms.
There is some evidence also that further amounts of these partial glycerides may be formed during the preparation of certain foods. Therefore, apart from any addition of these substances to food for technological purposes, they will always be present in the food as consumed.” [9] Mono- and diglycerides may contain small amounts of trans fat ...
This probably is an indication of the greater vulnerability of polyunsaturated fats to lipid peroxidation, against which vitamin E has been shown to be protective. [5] Examples of unsaturated fatty acids are palmitoleic acid, oleic acid, myristoleic acid, linoleic acid, and arachidonic acid.
