. Molecular weights of fatty acids vary over a wide range. The carbon skeleton of any fatty acid is unbranched. Some fatty acids are saturated, i.e., each carbon atom is connected to its carbon atom neighbors by single bonds; and some fatty acids are unsaturated, i.e., contain at least one carbon-carbon double bond (see chemical bondchemical bond,
mechanism whereby atoms combine to form molecules. There is a chemical bond between two atoms or groups of atoms when the forces acting between them are strong enough to lead to the formation of an aggregate with sufficient stability to be regarded as an

[¦fad·ē ′as·əd]
(organic chemistry)
An organic monobasic acid of the general formula Cn H2 n + 1COOH derived from the saturated series of aliphatic hydrocarbons; examples are palmitic acid, stearic acid, and oleic acid; used as a lubricant in cosmetics and nutrition, and for soaps and detergents.

Researchers from Karolinska Institutet in Solna, Sweden suggested that polyunsaturated fatty acids, omega-3 and omega-6 fatty acids are essential to life and the body is unable to produce itself, so they must be sourced from foods such as nuts and certain vegetable oils; and long-chain omega-3 fatty acids are primarily found in oily fish.
Higher total plasma omega-3 polyunsaturated fatty acids and individual omega-3 fatty acids EPA and DHA were associated with lower pulse wave velocity.
Based on emerging experimental data, such a strategy would not only prevent build-up of excessive storage "white" fat but may also enhance absorption of omega-3 polyunsaturated fatty acids while synergistically helping to normalize the overactive ECS.
It is known that increased intake of polyunsaturated fatty acids considerably lowers the level of serum cholesterol [16].
Effects of selenium supplementation on polyunsaturated fatty acid concentrations and antioxidant status in plasma and liver of lambs fed linseed oil or sunflower oil diets.
The researchers also wanted to know to what extent an increased intake of polyunsaturated fatty acids or saturated fatty acids was associated with deaths from CVD or CHD.
However, clinical benefits of the most abundant polyunsaturated fatty acid, omega 6 linoleic acid, have not been established.
The high concentration of polyunsaturated fatty acids (PUPA) in marine oils makes these oils extremely susceptible to oxidation, resulting in free radical formation, off-flavours and odours, and reduced shelf life.
Health implications of high dietary omega-6 polyunsaturated fatty acids.
By increasing the amount of omega-3 polyunsaturated fatty acids eaten by cattle, they hope to transfer the benefits to consumers.
The Study: In this double-blind, randomized, placebo-controlled study from Royal Perth Hospital Unit, University of Western Australia, Perth, 420 infants at high risk of developing allergies were either given fish oil as a source of omega-3 polyunsaturated fatty acids or a control (olive oil) from birth to age six months.
