A type of fat found in foods from plants and fish, such as sunflower oil, fish oil and some margarines and spreads. Eating polyunsaturated fats rather than saturated fats helps to reduce the blood cholesterol level.
Polyunsaturated fatty acids (PUFAs) have two or more double bonds and may be of two types, based on the position of the first double bond.
(polyunsaturated fat, polyunsaturates or polyunsaturated) means cis-methylene interrupted polyunsaturated fatty acids. ( acides gras polyinsaturés, graisses polyinsaturées, gras polyinsaturés, lipides polyinsaturés ou polyinsaturés) [B.01.001
Fatty acids whose carbon chains have one or more double bonds.
Fatty acids which contain more than one double bond (a type of chemical bond) in their structure.
fatty acids missing two or more pairs of hydrogen atoms.
The occurrence of two or more carbon to carbon double bonds in a fatty acid chain will result in a polyunsaturated fatty acid (see saturated fatty acids).
fatty acid with more than one double bond (or many carbons not bonded to a hydrogen atom)
Fatty acids with two or more points of unsaturation (more that one area in its molecular backbone in which there is a double carbon bond).
A type of unsaturated fatty acid in which the chain of carbon atoms is missing two or more pairs of hydrogen atoms. Polyunsaturated fatty acids are found in nuts and vegetable oils such as soybean, safflower and sunflower, and in fatty fish oils. When used instead of saturated fats, polyunsaturated fats tend to lower LDL cholesterol levels. Soybean oil contains approximately 61 percent polyunsaturated fatty acids.
