GLOBULINHO

GLOBULINHO (az lot. globuls – saqqocha, gululacha), guruhi safedahoi rastani va hayvonot, ki dar tabiat vase pahn shudaand. G. ba safedahoi globulini mansuband. Dar mahluli susti namakhoi mutadil, kislotahoi serob va ishqorho hal shuda, dar ob (ba gayr az miozin va baze dig. G.) hal nameshavand. Dar mahluli nimseri sulfati ammoniy, mahluli seri sulfati magniy (dar 300S) yo sulfati natriy (dar 370S) tahshin megardand. Aksari G. safedahoi soda meboshand, vale bazei onho (makhsusan G.-i zardobi khun) bo karbogidratho yo lipidho payvast gashtaand. G.-i gadudi siparshakl – tireoglobulin (massai mol. 630 000) – yagona safedaest, ki dar tarkibi khud yod dorad. G.-i boftahoi asab (neyroglobulin, neyrostromin) bo kislotahoi nukleat payvast meboshand. G.-i rastani (glitsilin, edestin, legumin va g.) nazar ba G.-i hayvonot ba tasiri spirt va harorat ustuvorii beshtar dorand. G. ba tarkibi sitoplazmaho, plazmai khun va limfa (dar hayvonoti darajai oli va odam) dokhil shuda, gunjoishi buferii onho va khosiyati masunii organizmro muayyan mekunand. Fraksiyai G.-i plazmai khun (gamma-globulinho), ki podtanhoi gunogun dorad, dar tib baroi peshgiri va muolijai bemorihoi siroyati istifoda meshavad.
Dar plazmai khun, gayr az G., albuminho niz mavjudand; tanosubi albumin/globulin ahamiyati tashkhisi dorad; az rui meyor on barobari 2 buda, hangomi bemorihoi iltihobi kam meshavad.
