Properties of fatty acids-

The essential fatty acids of vegetables oils have low melting point and Iodine number. Theyu become saturated fatty acids on hydrogenation and oils become solid fats.
Functions-
1) The essential fatty acid in high concentration along with the lipids constitutes the structural elements of tissue.
2) Lipids of gonads also contain aa high concentration of poly-unsaturated fatty acis which suggest the importance of reproductive function.
3) They affect the prolongation of clotting time and increase the fibrinilytic activity.
4) They retard atherosclerisis being esterified and emulsified with cholesterol and are incorporated into lipo-proteins for transport of liver for further oxidation.
5) They cure skin lessons.
6) They deficiencies of these acids in the diet of babies causes eczema.

Essentials of fatty acids-

The saturated fatty acids, which are not synthesized in the body and required for the growth and health, are called fatty acids. They are supplied for the diet. These are-
1) Linoleic acid
2) Linolenic acid
3) Arachidinic acid
The essential fatty acids in the high concentration along with structural elements of tissue lipid of gonads. It also contain high concentration of poly-unsaturated fatty acids, which suggest the importance of reproductive function. They affect the prolongation of clotting time and increase the fibrinolytic activity. They cure the skin lesions.
