  • Title: [Effect of the thyroid hormone, triiodothyronine on fatty acid chain elongation of mitochondrial phospholipids (author's transl)].
    Author: Rengel C, Rodríguez-Fernández C, Macarulla JM.
    Journal: Rev Esp Fisiol; 1979 Dec; 35(4):427-32. PubMed ID: 542705.
    Abstract:
    The effect of the Thyroid Hormone Triiodothyronine (T3) on composition of Fatty Acid of Mitochondrial Phospholipids is studied. In animals (Gallus domesticus var. Cornis and White Roc.) treated with an injection of T3 containing 0.04 microgram/g body weight, increase length and insaturation increases of the hydrocarbon chains of fatty acids in mitochondrial phospholipids are observed in relation to the corresponding controls. This elongation is maximum at 14 hours after treatment with the hormone. Animals treated with T3 showed a higher proportion of stearic and eicosatrienoic acids than controls. This increase is accompanied by an equivalent decrease of the palmitic and oleic acids, their respective biosynthetic precursors. The highest proportion of long chain and unsatured fatty acids can be observed in phosphatidylethanolamines and phosphatidylcholines.
