'''잔틴'''({{llang|en|xanthine}}) 또는 '''크산틴'''({{llang|de|Xanthin}})은 대부분의 인체 조직과 분비액, 다른 유기체에서 볼 수 있는 [[퓨린]] [[염기]]이다. 수많은 [[각성제]]가 [[카페인]]과 [[테오브로민]]을 포함하여 잔틴에서 비롯된다.<ref name="isbn0-8493-2647-8">{{서적 인용| author = Spiller, Gene A. | authorlink = | editor = | others = | title = Caffeine | edition = | language = | publisher = CRC Press | location = Boca Raton | year = 1998 | origyear = | pages = | quote = | isbn = 0-8493-2647-8 | oclc = | doi = | url = | accessdate = }}</ref>

잔틴은 [[퓨린 대사]] 방식의 산물이다.
* [[구아닌 탈아미 노효소]]의 [[구아닌]]
* [[잔틴 산화효소]]의 [[하이포잔틴]]
* [[퓨린 뉴클레오시드 가인산분해효소]](PNP)의 [[크산토신]]<ref>Voet, Donald; Voet, Judith; Pratt, Charlotte (2008). "The Major Pathways of Purine Catabolism in Animals," ''Fundamentals of Biochemistry: Life at the Molecular Level'', p. 840.</ref>.

잔틴은 [[잔틴 산화효소]]의 작용으로 말미암아 최종적으로 [[요산]]으로 변환된다.
