title: Changes in the triacylglycerol content of mitochondrial membranes during development.
abstract: The lipid content of mitochondria and mitochondrial membranes isolated from foetal, suckling, and adult rat liver mitochondria were compared. In foetal liver mitochondria triacylglycerol made up 26% of the lipids, while in adult rat liver mitochondria the triacylglycerol content was 7%. Esterified fatty acids originating from non-phospholipid sources amounted to 34% in mitochondrial membranes, and this amount decreased in mitochondrial membranes of adult rat liver to 22%. The concentration of phospholipids in the mitochondrial membranes did not change significantly during development.
