Choline bitartrate / From Wikipedia, the free encyclopedia
Choline bitartrate is an organic compound with the chemical formula [(CH3)3NCH2CH2OH]+HOOC−CH(OH)−CH(OH)−COO−. It is a white crystalline powder with an acid taste.[2] It is hygroscopic when exposed to air.[2] Modern texts refer to the choline salt of the natural form of tartaric acid, that is, the salt called choline dextrobitartrate, choline (2R,3R)-bitartrate or choline L-(+)-bitartrate.
