General description

Choline chloride is a quaternary ammonium salt and associates with hydrogen bond donors (HBD). It is essential for the vital physiological functions and is used as a nutritional additive. Choline is a source of methyl groups for methyl-transfer reactions.

Application

Choline chloride has been used:
  • as a component of choline acetyltransferase (ChAT) buffer and for choline uptake in cultured human neuroblastoma (SK-N-SH) cells
  • for choline standard curve generation for quantifying phospholipase D (PLD) activity
  • as a component of slice solution for the dissection of entorhinal-hippocampal brain slices

Substrates

Choline acetyltransferase substrate

Muscarinic acetylcholine receptors (mAChRs) are critically involved in hippocampal theta generation, but much less is known about the role of nicotinic AChRs (nAChRs). Here we provide evidence that α7 nAChRs expressed on interneurons, particularly those in oriens lacunosum moleculare (OLM)
