Propionyl-L-carnitine is a naturally occurring carnitine derivative formed by carnitine acetyltransferase during �²-oxidation of uneven chain fatty acids. Propionyl-L-carnitine increases the basal release of prostaglandin E2 (PGE2; Item No. 14010) and 6-keto-prostaglandin F1�± (Item No. 15210) in carrageenan-stimulated isolated rat peritoneal cells contaminated with neutrophils and increases the basal release of thromboxane B2 (TXB2; Item No. 19030) in non-contaminated cells. It reduces the production of reactive oxygen species (ROS) and decreases the expression of NADPH oxidase 2 (NOX2), NOX4, and ICAM-1 in human umbilical vein endothelial cells (HUVECs). It also increases the rate of revascularization and the hind limb vascular area in a rabbit model of hind limb ischemia when administered at a dose of 10 mg per animal. Propionyl-L-carnitine reduces mitochondrial dysfunction induced by ischemia, preventing mitochondrial calcium overload, and depletion of ATP tissue stores in a rabbit model of ischemia.

L-Carnitine

Product Name: L-Carnitine
Molecular Formula: C7H15NO3
Molecular Weight: 161.20
Appearance: white crystalline powder

Supplier: ZHENYIBIO

L-Carnitine is very easily soluble in water, and can be entirely absorbed by the human body when consumed through food. It is known that the small intestine absorbs L-carnitine, but there is little known about the specific absorption process of carnitine (free or esterified) through intestine mucosa and about the specific absorption area. Besides external food sources of carnitine, humans can also synthesize carnitine with their own bodies. The liver and kidneys are mainly responsible for synthesizing carnitine. They progress from lysine into epsilon beta hydroxy three methyl lysine, and use aldolase and aldehyde oxidase to transform it into L-carnitine. Besides lysine, the body's biosynthesis of L-carnitine also requires methionine, vitamin C, nicotinic acid and vitamin B6.

L-carnitine-L-tartrate (LCLT) is the salt of L-carnitine with tartaric acid. LCLT has potential chemoprotective and antioxidant activities
LCLT is used in foods as a source of L-carnitine for particular nutritional uses. It can be used to reduce soreness, improve oxygen flow, increase density of androgen receptors, and elevate post-exercise fat oxidation. LCLT also promotes human hair growth. LCLT is used as nutritional therapy in the treatment of fatty liver and hemorrhagic shock in pharmaceutical and as a nutritional supplement in agriculture/animal feed to increase the growth rate and reduce the fat rate of aquatic animal.
