I-Betaineisetshenziswa njengento edonsela ukudla ezilwaneni zasemanzini.

Ngokusho kwemithombo yangaphandle, ukwengeza i-betaine engu-0.5% kuya ku-1.5% ekudleni kwezinhlanzi kunomthelela omkhulu ovuselelayo ezinzweni zokuhogela nezokudla zazo zonke izilwane ezinamagobolondo njengezinhlanzi nama-shrimp. Kunokukhanga okunamandla kokudla, kuthuthukisa ukunambitha kokudla, kunciphisa isikhathi sokudla, kukhuthaza ukugaya nokumunca, kusheshise ukukhula kwezinhlanzi nama-shrimp, futhi kugweme ukungcola kwamanzi okubangelwa ukungcola kokudla.

I-Betaineiyisithako esivikela ukuguquguquka kwengcindezi ye-osmotic futhi ingasebenza njengesivikelo se-osmotic seseli. Ingathuthukisa ukubekezelelana kwamaseli ezinto eziphilayo esomeni, umswakama ophezulu, usawoti omningi, kanye nezindawo eziphezulu ze-osmotic, ivimbele ukulahleka kwamanzi eseli kanye nokungena kukasawoti, ithuthukise umsebenzi wephampu ye-Na K yama-membrane eseli, izinzise umsebenzi we-enzyme kanye nomsebenzi we-macromolecule wezinto eziphilayo, ilawule ingcindezi ye-osmotic yeseli lezicubu kanye nebhalansi ye-ion, igcine umsebenzi wokumunca izakhamzimba, futhi ithuthukise izinhlanzi Lapho ingcindezi ye-osmotic yezinhlanzi nezinye izinto eziphilayo idlula ezinguqukweni ezinkulu, ukubekezelelana kwazo kuyanda futhi izinga lokusinda kwazo liyakhula.

 I-Betaineingaphinde inikeze amaqembu e-methyl emzimbeni, futhi ukusebenza kwayo kahle ekuhlinzekeni amaqembu e-methyl kuphindwe izikhathi ezingu-2.3 kune-choline chloride, okwenza kube ngumnikeli we-methyl osebenza kahle kakhulu. I-Betaine ingathuthukisa inqubo yokuxiliswa kwama-fatty acids kuma-mitochondria amaseli, ikhuphule kakhulu okuqukethwe kwe-acyl carnitine ye-chain ende kanye nesilinganiso se-acyl carnitine ye-chain ende ukuze ikhulule i-carnitine emisipheni nasesibindini, ikhuthaze ukubola kwamafutha, inciphise ukufakwa kwamafutha esibindini nasemzimbeni, ikhuthaze ukwakheka kwamaprotheni, isakaze kabusha amafutha esidumbu, futhi inciphise izinga lokwenzeka kwesibindi esinamafutha.
