l-carnitine hydrochloride

L-Carnitine hydrochloride ((R)-Carnitine hydrochloride) is a highly polar small zwitterionic molecule that functions as an essential cofactor for mitochondrial β-oxidation. L-Carnitine hydrochloride facilitates the transport of long-chain fatty acyl-CoAs into mitochondria for subsequent degradation via β-oxidation, thereby supporting cellular energy metabolism. L-Carnitine hydrochloride also displays antioxidant activity and can mitigate metabolic imbalances associated with numerous inborn errors of metabolism, positioning it as an important agent in metabolic research.

D-Carnitine hydrochloride ((S)-Carnitine Hydrochloride) is a component of striated muscle and liver, used therapeutically to stimulate gastric and pancreatic secretions and to treat hyperlipoproteinemias.

Acetyl-L-carnitine hydrochloride (Acetyl L-carnitine hydrochloride) is a nutritional supplement composed of the hydrochloride salt form of the acetylated form of the endogenously produced L-carnitine, with potential neuroprotective, cognitive-enhancing, anti-depressive and immunomodulating activities. It may also relieve peripheral neuropathy induced by chemotherapy, diabetes or other diseases. In addition, acetyl-L-carnitine may modulate the immune response by increasing T-lymphocytes maturation and may downregulate pro-inflammatory cytokines in response to viruses, such as SARS-CoV-2. It may also disrupt the ACE2 signaling pathway and inhibit the production of reactive oxygen species (ROS).
