[Biological properties of vegetable oils containing linolenic acid (18:3 omega 3)]
Abstract:
Experiments on growing albino male rats were made to study the food value of the vegetable oils: soybean and rapeseed ones containing different quantities of linolenic acid. These oils were included in the animals' diet in the amount of 25% with respect to caloric value for 12-13 weeks. It has been established that as the content 18:3 omega 3 in the food fat was reduced, the metabolism of fatty acids in the body improved, manifesting in a noticeable rise of the efficacy of food fatty acids metabolization. This process was affected not only by the ratio 18:3 omega 3 and 18:2 omega 6 in the food fat but also by the total balance in it of fatty acids.
