Half‐lives of docosahexaenoic acid in rat brain phospholipids are prolonged by 15 weeks of nutritional deprivation of n‐3 polyunsaturated fatty acids

JC DeMar Jr, K Ma, JM Bell… - Journal of …, 2004 - Wiley Online Library
Male rat pups (21 days old) were placed on a diet deficient in n‐3 polyunsaturated fatty
acids (PUFAs) or on an n‐3 PUFA adequate diet containing α‐linolenic acid (α‐LNA; 18 : 3n‐3). …

α‐Linolenic acid does not contribute appreciably to docosahexaenoic acid within brain phospholipids of adult rats fed a diet enriched in docosahexaenoic acid
