Our bodies are made up of fats, proteins, and carbohydrates which account for about 38% and the rest is water. Most of the fat in the form of triglycerides, which is an ester of glycerol with three fatty acids are the same or different.
Several types of fatty acids in the body can be grouped into plural unsaturated fatty acids known as PUFA (Poly Unsaturated Fatty Acids). It is a group of fatty acids that are very important for human health and can not be replaced by other compounds.
Consists of the parent PUFA fatty acids or essential, essential fatty acids (EFA) and the unsaturated fatty acid derivatives of long-chain or long chain poly unsaturated derivatives (LCPUFA). EFAs can not disentesa de novo (in the body) human. Therefore, EFAs must be consumed part of the menu.
There are two groups of PUFA namely Omega 6 and Omega 3, which successively synthesized from linoleic acid (ALA) and alpha linolenic acid (Alna).
LA and Alna through the process of desaturation and elonggasi in the human body cells in a row is converted into long chain n-6 PUFA (omega-6) and long chain n-3 PUFAs (omega-3).
In the process of conversion of LA and Alna, there is a tight competition to compete for the same enzymes. Naturally, Alna (Omega 3) has a higher affinity for it.
Long chain n-6 PUFA is the most important in homo-gamma-linolenic (DHGLA) and arachidonic acid (AA). While the long chain n-3 PUFAs eicosapentaenoic acid is the most important (EPA) and decohexaenoic acid (DHA).
The main function of EFAs, LC n-6 PUFA and LC n-3 PUFA is a structural and functional components of the cell membrane. Therefore, they are essential for the formation of the body tissues.
Levels of LC n-6 PUFA and LC n-3 PUFA in the membrane and the ratio is known to strongly influence biological processes, such as membrane fluidity, transport nutrients, enzyme activity attached to the membrane, and receptor function.
Coronary Vascular Disease (CVD) is often equated with Coronary Heart Disease (CHD) or coronary heart disease. CVD prevention programs are generally focused on how to reduce serum cholesterol levels (especially LDL) by reducing the total consumption of fat (especially saturated fat) and cholesterol and increasing consumption of PUFA.
