[Conjugated linolenic acids (CLnA, super CLA)--natural sources and biological activity].
Polyunsaturated fatty acids (PUFA) have a wide range of biological activity. Among them conjugated fatty acids are of great interest. Conjugated linoleic acids (CLA), which exert a multidirectional health-benefiting influence, and conjugated linolenic acids (CLnA, super CLA) are examples of this group of fatty acids. CLnA are a group of positional and geometric isomers of octadecatrienoic acid (C18:3), which possess double bonds at positions 9, 11, 13 or 8, 10, 12 of their chain. Some vegetable oils are rich sources of CLnA, e.g. bitter melon oil (from Momordica charantia seeds) and pomegranate oil (from Punica granatum seeds). The aim of this paper was to present information concerning natural sources and health-promoting activities of conjugated linolenic acids. The presented data reveal that conjugated linolenic acids may be very useful in prevention and treatment of many diseases, especially diabetes, arteriosclerosis , obesity and cancers (mammary, prostate and colon cancer). Among many potential mechanisms of their action, the fact that some CLnA are converted by oxidoreductases into CLA is very important. It seems to be very reasonable to conduct research concerning the possibility of CLnA use in prevention of many diseases.
