Betaineikoreshwa nk'ikintu gikurura inyamaswa zo mu mazi.

Nk’uko amakuru aturuka mu mahanga abivuga, kongeramo 0.5% kuri 1.5% bya betaine mu biryo by’amafi bigira ingaruka zikomeye ku buryo bwo guhumeka no kurya kw’inyamaswa zose zo mu bwoko bwa crustacean nka amafi n’isambaza. Bikurura cyane ibiryo, binoza uburyo ibiryo biryoha, bigabanya igihe cyo kubirya, bitera igogora no kubisya, byihutisha gukura kw’amafi n’isambaza, kandi birinda kwanduzwa n’amazi guterwa n’imyanda y’ibiryo.

Betaineni ikintu gikingira ihindagurika ry’umuvuduko wa osmotike kandi gishobora gukora nk'uburinzi bwa osmotike y'ingirabuzimafatizo. Gishobora kongera ubushobozi bwo kwihanganira uturemangingo tw’ibinyabuzima mu gihe cy’amapfa, ubushuhe bwinshi, umunyu mwinshi, n’ibidukikije byinshi bya osmotike, kikarinda ibura ry’amazi n’umunyu byinjira mu turemangingo, kikanoza imikorere ya Na K pompe y’uturemangingo, kikatuza imikorere ya enzyme n’imikorere ya macromolecule y’ibinyabuzima, kikagenzura umuvuduko wa osmotike y’uturemangingo tw’uturemangingo n’uburinganire bwa iyoni, kikabungabunga imikorere yo kwinjiza intungamubiri, kandi kikanoza amafi Iyo umuvuduko wa osmotike w’udusimba n’ibindi binyabuzima bihuye n’impinduka zikomeye, ubushobozi bwabyo bwo kwihanganira buriyongera kandi umuvuduko wabyo wo kubaho uriyongera.

 Betaineishobora kandi gutanga amatsinda ya methyl ku mubiri, kandi ubushobozi bwayo mu gutanga amatsinda ya methyl ni inshuro 2.3 z'icya koline chloride, bigatuma iba umutanga wa methyl mwiza kurushaho. Betaine ishobora kunoza inzira yo ogisijeni ya aside irike muri mitochondria y'uturemangingo, yongera cyane ingano ya acyl carnitine y'uruhererekane rurerure n'ikigereranyo cya acyl carnitine y'uruhererekane rurerure ijya mu mitsi no mu mwijima, iteza imbere gusenyuka kw'ibinure, igabanya ibinure byinjira mu mwijima no mu mubiri, iteza imbere imikorere ya poroteyine, yongera gukwirakwiza ibinure by'inyamaswa, kandi ikagabanya umuvuduko w'ubwiyongere bw'ibinure mu mwijima.
