Description:
Carnitin, genauer L-Carnitin, ist eine natürlich vorkommende, chemische Verbindung, die aus den Aminosäuren Lysin und Methionin hergestellt wird. Es spielt eine essentielle Rolle im Energiestoffwechsel tierischer und pflanzlicher Zellen. L-Carnitin fungiert als Rezeptormolekül für aktivierte Fettsäuren im Cytosol und in Zellorganellen wie den Mitochondrien. Es übt diese Funktion im Wechselspiel mit Coenzym A aus. Langkettige Fettsäuren können nur gebunden an L-Carnitin durch die Mitochondrienmembranen transportiert werden.
While it is often categorized as an amino acid, L-carnitine isn't technically an amino. It is considered a "vitamin-like" and "amino acid-like" compound that is related to the B vitamins. When it was first studied back in the 1950s, L-carnitine was referred to as vitamin BT.
L-carnitine is formed in the liver and kidneys from the amino acids lysine and methionine. However, it is stored elsewhere in the body, primarily in muscle (including the heart), the brain, and even in sperm. In the diet, it mainly comes from meat and other animal products. You can get some from plant products like avocado and soybeans, but as a rule, meat is the best source—and the redder the better.
Carnitine exists in two forms, D-carnitine and L-carnitine. The L-form is the one found in nature and is biologically active. On labels, you'll see it listed as L-carnitine, L-carnitine L-tartrate, or Propionyl-L-carnitine. They're all similar, and similarly effective. The D form, on the other hand, is biologically inactive and isn't sold as a supplement.
Applications:
L-carnitine supplements are used to increase L-carnitine levels in people whose natural level of L-carnitine is too low because they have a genetic disorder, are taking certain drugs (valproic acid for seizures), or because they are undergoing a medical procedure (hemodialysis for kidney disease) that uses up the body’s L-carnitine. It is also used as a replacement supplement in strict vegetarians, dieters, and low-weight or premature infants.
L-carnitine is used for conditions of the heart and blood vessels including heart-related chest pain, congestive heart failure (CHF), heart complications of a disease called diphtheria, heart attack, leg pain caused by circulation problems (intermittent claudication), and high cholesterol.
Some people use L-carnitine for muscle disorders associated with certain AIDS medications, difficulty fathering a child (male infertility), a brain development disorder called Rett syndrome, anorexia, chronic fatigue syndrome, diabetes, overactive thyroid, attention deficit-hyperactivity disorder (ADHD), leg ulcers, Lyme disease, and to improve athletic performance and endurance.
