Betaineikoreshwa nkibiryo bikurura inyamaswa zo mu mazi.

Nk’uko amakuru aturuka mu mahanga abivuga, kongeramo 0.5% kugeza kuri 1.5% ya betaine mu biryo by’amafi bigira ingaruka zikomeye ku myuka ya olfactory na gustatory yumutima wa crustaceans zose nk'amafi na shrimp. Ifite ibyokurya bikurura cyane, itezimbere ibiryo, igabanya igihe cyo kugaburira, itera igogorwa no kwinjirira, yihutisha imikurire n’urusenda, kandi irinda kwanduza amazi guterwa n’imyanda y’ibiryo.

Betaineni ibintu bya buffer kugirango ihindagurika ryumuvuduko wa osmotic kandi irashobora kuba nkingirabuzimafatizo ya selile. Irashobora kongera imbaraga mu kwihanganira ingirabuzimafatizo ku binyabuzima, ubuhehere bwinshi, umunyu mwinshi, hamwe n’ibidukikije byinshi bya osmotique, bikarinda gutakaza amazi y’utugari no kwinjira mu munyu, kunoza imikorere ya pompe ya Na K ya selile, guhagarika ibikorwa bya enzyme n’imikorere ya macromolecule, kugenga umuvuduko w’ingirabuzimafatizo ya osmotic no kuringaniza intungamubiri byongera ubuzima bw’imisemburo hamwe n’ibindi binyabuzima.

 BetaineIrashobora kandi gutanga amatsinda ya methyl kumubiri, kandi imikorere yayo mugutanga amatsinda ya methyl yikubye inshuro 2,3 ya chorine chloride, bigatuma itanga methyl ikora neza. Betaine irashobora kunoza uburyo bwa okiside ya acide yibinure muri mitochondria ya selile, ikongera cyane muburyo bwa acyl karnitine yumunyururu muremure hamwe nigipimo cya acyl karnitine yumunyururu muremure na karnitine yubusa mumitsi numwijima, bigatera kwangirika kwamavuta mumwijima no mumubiri, bigatera ibinure byumwijima, bikagabanya ibinure byumwijima.
