Dimethyl-propiothetin (DMPT)ke algae metabolite.Ke motsoako oa tlhaho o nang le sebabole (thio betaine) 'me o nkoa e le leraba la phepo e ntle ka ho fetisisa, bakeng sa liphoofolo tse phelang metsing a hloekileng le a leoatle.Litlhahlobong tse 'maloa tsa laborateng le masimong DMPT e tsoa e lesehlahisoa se setle ka ho fetisisa se susumetsang phepelo se kileng sa lekoa.

DMPT(Cas NO.7314-30-9)ha e ntlafatse phepelo feela, empa hape e sebetsa joalo ka ntho e kang ea li-hormone tse qhibilihang ka metsing.Ke methyl donor e sebetsang ka ho fetesisa e fumanehang, e ntlafatsa bokhoni ba ho sebetsana le khatello ea maikutlo e amanang le ho tšoasa / ho tsamaisa litlhapi le liphoofolo tse ling tsa metsing.

Molemo oa Sehlahisoa oa DMPT:

1.Fana ka methyl bakeng sa liphoofolo tse phelang metsing, ho khothalletsa ho tsosolosoa ha li-amino acid le ho eketsa bioavailability ea amino acid;

2. Sehohelo se matla se ka susumetsang boitšoaro ba ho fepa liphoofolo tsa metsing le ho eketsa makhetlo a tsona a ho fepa le ho ja lijo;

3. E-ba le ts'ebetso ea ecdysone, e ka eketsang sekhahla sa ho tsoa ha crustacean;

4. Laola khatello ea osmotic, le ho eketsa bokhoni ba ho sesa le ho thibela khatello ea kelello ea litlhapi;

5. Fokotsa karolo ea lijo tsa tlhapi lijong le ho eketsa ts'ebeliso ea mehloli e meng ea protheine e batlang e le theko e tlase.

Tšebeliso le litekanyetso:

Shrimps: 300-500 g ka tone ea lijo tse feletseng;

Litlhapi: 150-250 g ka tone ea phepo e felletseng.
