<prompt> I-heparin ngokuvamile igcinwa ngaphakathi kwama-granules e-secretory of mast cells futhi ikhishwa kuphela ku-vasculature ezindaweni zokulimala kwezicubu. Kuye kwaphakanyiswa ukuthi, kunokuba i-anticoagulation, injongo eyinhloko ye-heparin ukuzivikela ezindaweni ezinjalo ngokumelene namagciwane ahlaselayo nezinye izinto zangaphandle. Ngaphezu kwalokho, ibonwa ezinhlotsheni eziningi ezahlukahlukene kakhulu, kufaka phakathi ezinye izilwane ezingenamgogodla ezingenayo uhlelo olufanayo lokuqunjelwa kwegazi. I-glycosaminoglycan ene-sulfated kakhulu. Inesilinganiso esiphakeme kakhulu sokushaja kwe-negative yanoma iyiphi i-molecule eyaziwayo. Umbuzo: Inhloso eyinhloko ye-heparin, manje ebuzwayo, ngokuvamile ibizwa ngokuthi yini?  <response>: ukuvimbela ukwakheka kwegazi
