Supplementation with dietary EPA/DHA influences red blood cell fatty acid desaturase estimates and reflects tissue changes in fatty acids in systemic organs

Delta-5-desaturase (D5D) and delta-6-desaturase (D6D) are critical in polyunsaturated fatty acid (PUFA) metabolism. D5D and D6D catalyze the conversion of linoleic acid (LA) into arachidonic acid (...
