Biological Activity

Phosphocholine chloride calcium salt tetrahydrate is an active endogenous metabolite and a key intermediate in the de novo biosynthesis of phosphatidylcholine through the Kennedy pathway. Produced from choline phosphorylation by choline kinase, it is further converted into cytidine diphosphate-choline to maintain cellular membrane integrity, lipid homeostasis, and vital intracellular metabolic pathway functions.

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).
