Changes in the triacylglycerol content of mitochondrial membranes during development.
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.
