The MDA synthesis was investigated in male Wistar rats which were given various fats, such as soybean , fish , and evening primrose oils, as well as mixture of evening primrose and fish oils. Received results show that there is a clear correlation between the kind and quantity of PUFA present in the diet and possibilities of synthesis of free or protein bounded MDA. The animals' age was possitively correlated with these alterations.
