Biological Activity

Propionyl-L-carnitine hydrochloride is a naturally occurring carnitine derivative that supports mitochondrial energy metabolism and cellular respiration. It enhances ATP production by facilitating fatty acid transport into mitochondria and supplying propionate for citric acid cycle intermediate replenishment. Additionally, propionyl-L-carnitine acts as an antioxidant free radical scavenger, protecting vascular endothelial cells from oxidative stress and improving cardiovascular function.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
