title: [Metabolism of [1-(14)C]arachidonic acid in ruminant tissues during the pre- and postnatal periods of development under in vitro conditions].
abstract: After in vitro incubation of liver, skeletal muscle and adipose tissues from the fetuses and adult cattle as well as of placenta tissue with [1-14C]arachidonic acid, about 90% of the radioactive label was found in the lipids, 10%-in the prostaglandins, and 0.1%-in 14CO2. Arachidonic acid was utilized for the synthesis of lipids and prostaglandins in the majority of fetal tissues in a much greater degree, whereas that in energy-linked process--in a smaller degree compared with adult cattle tissues. [1-14C]arachidonic acid metabolism in the placenta and liver of the given species proceeds much more intensely than that in the skeletal muscles and adipose tissue. In tissues of adult animals [1-14C]arachidonic acid is predominantly utilized for the synthesis of phospholipids, whereas that in fetal tissues is utilized for the synthesis of phospholipids, cholesterol, esters and triglycerides.
