2.6 Se SEBELISANG TSA HO QETELA
HPMC e ka sebelisoa e le mofani oa li-amilers tse omileng (DPIS) ho ntlafatsa phallo ea phofo, ho eketsa sekhahla sa lithethefatsi, 'me ka hona ho ntlafatsa phello ea kalafo.
3. Melemo ea HPMC ho litokisetso tsa ho lokolloa
HPMC e na le litšobotsi tse latelang e le ea ho lokolla:
Seteishene se setle sa metsi:E ka ruruha ka potlako metsing ho etsa tšitiso ea moferefere ebe e laola sekhahla sa lithethefatsi.
Setsi se hantle:e seng chefo ebile e se khopisang, e sa ananele ke 'mele oa motho,' me e na le tsela e hlakileng ea metabolic.
Ho ikamahanya le maemo:E loketseng mefuta e fapaneng ea lithethefatsi, ho kenyelletsa lithethefatsi tse qhibilihang metsing le hydrophobic.
