1. Biosynthesis of L-carnitine
Substances required for carnitine synthesis: Lys, Met, VB3, VB6, VC, Fe2+.
The main sites of synthesis in the body are the liver and kidneys. It is synthesized by lysine a and methionine with the participation of VC, niacin, VB6 and iron. The deficiency of any of these nutrients will affect the synthesis of L-carnitine.
Although the content of carnitine in skeletal muscle cells is high, skeletal muscle does not synthesize carnitine, and the carnitine in skeletal muscle is also transported through the blood.
L-carnitine belongs to amino acid substances. Amino acids will not be decomposed by gastric acid, so carnitine will not be decomposed either.
There are even studies that show that L-carnitine can be placed in a solution of pH 3~6 for more than one year.
2. L-carnitine is a compound related to energy metabolism in animals, and its functions include:
(1). Promotes fatty acid β-oxidation. It can increase the oxidation rate of fat, reduce glycogen consumption, and delay fatigue during high-intensity exercise.
(2). Regulate the acyl ratio in mitochondria.
(3). Collect excess or irrational acyl groups.
(4). Affect the metabolism of amino acids.
(5). Combines with urea to promote the elimination of ammonia in the body and prevent excessive ammonia from causing toxicity.
(6). Has a certain effect on the absorption of fat-soluble vitamins and calcium and phosphorus.
(7). Indirectly participates in the process of gluconeogenesis.
(8). Participates in the maturation of sperm.
