L-α-Glycerophosphorylcholine (alpha-GPC, choline alfoscerate, sn-glycero-3-phosphocholine) is a natural choline compound found in the brain. It is also a parasympathomimetic acetylcholine precursor [ 1 ] which has been investigated for its potential for the treatment of Alzheimer's disease [ 2 ] and other dementias .
GPC is often used to determine the relative molecular weight of polymer samples as well as the distribution of molecular weights. What GPC truly measures is the molecular volume and shape function as defined by the intrinsic viscosity. If comparable standards are used, this relative data can be used to determine molecular weights within ± 5% ...
