“…In this experiment these differences were statistically not significant. However, in experiments performed by Scheier and Williams [19] a significant increase of hepatic AA concentration, caused by vitamin B 6 supplementation, and an increase of AA concentration in hepatic phospholipids of rats initially fed low-protein and lowfat diet and then the diet supplemented with pyridoxine was observed. This effect of vitamin addition was the strongest at the beginning of B 6 supplementation.…”

The influence of vitamin B6 on fatty acids content in serum and liver of rats receiving low protein diets was studied. Addition of B6 decreased linoleic acid (LA) and increased alpha-linolenic acid (ALA) and docosahexaenoic acid (DHA) in serum of rats fed a protein-deficient diet (9% energy from proteins) for 3 months. Further restriction of dietary protein (4.5% of energy from protein) caused an increase of the DHA concentration and sum of polyunsaturated fatty acids (PUFAs). In the liver of undernourished rats significant changes of PUFA composition were noticed, although without any significant influence of vitamin B6.

In rats deficient in pyridoxine and essential fatty acids, liver phospholipids contained less arachidonic acid and more oleic and eicosatrienoic acids than those from animals only deficient in essential fatty acids. This pattern persisted after the animals were supplemented with linoleate for 6 days. Liver oleyl and arachidonyl CoA‐lysophospholipid acyltransferase activities were significantly higher in pyridoxine‐deficient animals. Supplementation with linoleate for 6 days resulted in a marked increase in arachidonyl CoA‐acyltransferase activity in pyridoxine‐deficient rats but a relatively small increase in the supplemented animals. Differences in fatty acid composition between pyridoxine‐deficient and supplemented rats can not be ascribed to lower liver transacylase activity in the deficient animals.
