'''Citrullinum''' (de [[citrullus|citrullo lanato]]) in [[chemia]] est α-[[acidum aminicum]], non in [[proteinum|proteinis]] inventum.<ref>''Pubchem'' [https://pubchem.ncbi.nlm.nih.gov/compound/833#x291 de citrullino].</ref> In [[cyclus ureae|cyclo ureae]] adhibetur, et in duabus e suis perturbationibus [[genetica|geneticis]] in [[sanguis|sanguine]] accumulat, ambae [[citrullinaemia]] appellatae. 

Praeterea functionem intestini et absorptionem in intestinum indicare possunt.

== Natura chemica ==
Formula chemica sua est {{chem|C|6|H|13|N|3|O|3}}, et [[massa molaris]] 175.188 g/mol. Citrullinum est compositum parentale ''classis citrullinorum'', una cum [[ornithinum|ornithino]]. 

Nomen plenum chemicum est acidum 2-amino-5-(carbamoylo-amino)-pentanoicum. [[Acidum valericum|Acido valerico (pentanoico)]] positione 5 sua per gregrem amini grex carbamoyli nexus est, et positione 2 grex alius amini locatus est.

== Usus diagnosticum ==
Citrullinum constanter ex [[intestinum|intestino]] in sanguinem liberatur. Citrullinum functionem intestini et absorptionem in intestinum indicare possunt<ref>{{cite journal |authors=Fragkos K. C., Forbes A. |title=Citrulline as a marker of intestinal function and absorption in clinical settings: A systematic review and meta-analysis |journal=United Europea gastroenterology journal |year=2018 |volume=6 |issue=2 |pages=181-91 |url=https://www.ncbi.nlm.nih.gov/pubmed/29511548}}</ref>, indicator et mali acuti et chronici.
