Editing Choline (section)

==Uses==
Choline [[chloride]] and choline [[bitartrate]] are used in [[dietary supplement]]s. Bitartrate is used more often due to its lower hygroscopicity.<ref name=ze/> Certain choline salts are used to supplement chicken, turkey and some other [[animal feed]]s. Some salts are also used as industrial chemicals: for example, in [[photolithography]] to remove [[photoresist]].<ref name="lpi"/> [[Choline theophyllinate]] and choline [[salicylate]] are used as medicines,<ref name="lpi"/><ref>{{Cite book|title=Community pharmacy: symptoms, diagnosis, and treatment|vauthors=Rutter P|publisher=Elsevier|year=2017|isbn=9780702069970|edition=4th|pages=156}}</ref> as well as [[structural analog]]s, like [[methacholine]] and [[carbachol]].<ref name="KOECT">{{cite book | chapter = C2-Chlorocarbons to Combustion Technology |title=Kirk-Othmer encyclopedia of chemical technology | veditors = Howe-Grant M, Kirk RE, Othmer DF |publisher=John Wiley & Sons |year=2000 |isbn=9780471484943 |edition=4th |volume=6 |pages=100–102 |display-authors=etal }}</ref> [[Radiolabeled]] cholines, like [[carbon-11-choline|<sup>11</sup>C-choline]], are used in [[medical imaging]].<ref>{{cite journal | vauthors = Guo Y, Wang L, Hu J, Feng D, Xu L | title = Diagnostic performance of choline PET/CT for the detection of bone metastasis in prostate cancer: A systematic review and meta-analysis | journal = PLOS ONE | volume = 13 | issue = 9 | pages = e0203400 | date = 2018 | pmid = 30192819 | pmc = 6128558 | doi = 10.1371/journal.pone.0203400 | bibcode = 2018PLoSO..1303400G | doi-access = free }}</ref> Other commercially used salts include tricholine [[citrate]] and choline [[bicarbonate]].<ref name="lpi"/>

The most common forms of dietary choline supplements are shown in the following table:
