the study of serum carnitine, triglyceride and cholesterol changes in pregnant and non-pregnant women

carnitine is a water-soluble quaternary amine which increases the long-chain fatty acid metabolism by facilitation of their transport to the oxidation site (mitochondria). carnitine most likely is present in all animal species, in many microorganisms, and in many plants. in this study, we determined the carnitine level of sera in pregnant and non-pregnant women by segade modified method. average concentration of carnitine in the sera of fifty pregnant women was about 25/83 umol/i: first trimester-30.96 umol/i. second trimester-29.11 umol/i. third trimester-25.11 umol/i. concentration of cholesterol and triglyceride in the above-mentioned group was the following: cholesterol: 258.84 mg/dl triglyceride: 267.02 mg/dl. the above values show that the carnitine level in sera of pregnant women decreases significantly and this decrease is tolerated well by pregnant women. according to our results, the serum carnitine concentration in pregnant women gradually decreases as gestation proceeds. so that the end of this period, is half of its concentration before conception. during pregnancy, there was an inverse correlation between carnitine level and that of cholesterol and triglycerides. decrease in carnitine concentration and increase in cholesterol and triglyceride levels may be due to the following factors: 1) increase in ffa oxidation in pregnancy. 2) hormones. 3) dilution of the blood. 4) decrease in fe storage in pregnant women.
