Role of Carnitine in Lipid Metabolism
A major function of lipids in modern nutrition is to serve as a substrate for production of metabolic energy. Mechanisms regulating the production of metabolic energy under a wide variety of physiological conditions are required for survival of the species. The critical role of carnitine in the production of energy from longchain fatty acids is well recognized. As illustrated in Fig. 1, carniti...
متن کاملLow carnitine intake and altered lipid metabolism in infants.
We examined the effect of dietary carnitine on variables of lipid metabolism in human infants. Normal male full-term infants were fed an isolated soy-protein-based formula with or without added carnitine from age 6-9 d to age 112 d. Growth and food intake were measured throughout the study. At ages 56 and 112 d serum concentrations of carnitine, free fatty acids, and triglycerides and urinary e...
متن کاملThe Effect of Chronic Intake of L-carnitine L-tartrate on Lipid Metabolism during Aerobic Exercise
Background & Aims: Despite 20 years of research, there is no compelling evidence about the effect of carnitine supplementation on improving physical performance in healthy subjects. The aim of this study was to determine the effect of long term consumption of acute L-carnitine L-tartarate (LCLT) on fat metabolism and aerobic capacity. Methods: A total of 28 healthy nonathlete male students rece...
متن کامل-carnitine supplementation restores decreased tissue carnitine levels and impaired lipid metabolism in aged rats
The effects of long-term carnitine supplementation on age-related changes in tissue carnitine levels and in lipid metabolism were investigated. The total carnitine levels in heart, skeletal muscle, cerebral cortex, and hippocampus were 20% less in aged rats (22 months old) than in young rats (6 months old). On the contrary, plasma carnitine levels were not affected by aging. Supplementation of ...
متن کاملAcetyl-L-carnitine supplementation restores decreased tissue carnitine levels and impaired lipid metabolism in aged rats.
The effects of long-term carnitine supplementation on age-related changes in tissue carnitine levels and in lipid metabolism were investigated. The total carnitine levels in heart, skeletal muscle, cerebral cortex, and hippocampus were approximately 20% less in aged rats (22 months old) than in young rats (6 months old). On the contrary, plasma carnitine levels were not affected by aging. Suppl...
