Starch: ifomula, iimpawu kwakunye nokunye okuninzi

Chemicals - isayensi elikhethekileyo umdla, ngoncedo apho umntu achaze iinkqubo ezininzi ezithi zenzeke ngeenxa zonke kuthi ebomini. Ngokomzekelo, kutheni siyarusa zentsimbi kancinane, yaye kutheni aluminiyamu icephe ngokukhawuleza kumo xa nkxu neti eshushu. Chemistry ubajikelezile naye ngokupheleleyo kuthi yonke: acetic acid okanye iviniga, sodium chloride okanye ityuwa itafile ezaziwayo wonke, yaye izinto ezifana iodine, iblitshi, utywala kunye nabanye. Kodwa kukho chemistry na into ethe yaziwa wonke, yaye ibizwa ngokuba istatshi. Starch ungafumaneka kwakhona yi acid, kodwa eyona nto licatshulwa neetapile. Makhe sihlolisise, yonke into enxulumene nayo, ekuqaleni nasekupheleni kohambo kunye nefomula eekhemikhali iimpawu zayo nendlela starch abonakala ngayo.

Starch, MDM ifomyula ngolu hlobo lulandelayo: S6N10O5, kukho inani iipropati umdla. Umzekelo, ijeli oyithandayo wonke ngumkhenkce kuphela ngenxa yokuba iqulethe isixa esikhulu ngokwaneleyo bestatshi. Kubonakala ngathi ngumgubo wesitatshi eqhelekileyo esha, phantse akanayo ukungcamla, kodwa into umdla kukuba creaks nge miri kancinane. Le impahla emzimbeni wesitatshi ngenxa yokuba ezo molekyuli otashi inkulu ngokwaneleyo.

Ngokubanzi, starch, ifomula yaye ezinye izakhiwo zalo esafunyanwa kakhulu kutshanje. Starch eziveliswa zizityalo, hayi iitapile kuphela, kodwa abanye ezifana, ngokomzekelo, nombona kunye nengqolowa. Istatshi itapile iqulethe ekhulwini mabini kuphela, nengqolowa kunye ingqolowa wokudla lidlula uphawu asixhenxe ekhulwini. Starch kwakheka xa compound na photosynthesis molekyuli ezintandathu carbon dioxide kunye molekyuli ezintlanu yamanzi, apho zinemoletyhule starch enye ezintandathu molecule oksijini.

Njengoko kuboniswe ngasentla, ifomula eekhemikhali wesitatshi iqulethe athom carbon ezintandathu, athom hydrogen ezilishumi athom ezintlanu neoksijini. Oku kubonisa nje kuphela ukuba molecule otashi mkhulu kakhulu, kodwa ukuba unalo imvelaphi eziphilayo ngokupheleleyo, okt, i njengomncedisi emasimini of chemistry, ebizwa organic. Le into ithathwa ngokuba entsonkothileyo, libhekisela candelo polysaccharides, nangona iswekile okanye izinto ezifana ngayo ayikho. Kwakhona starch ibhekisa nezinto eziphilayo equlethe umoya okanye ngenye indlela - le khompawundi organic ioksijini-equlethe.

Le ndlela yokubala noshowo of wesitatshi kwakhona ingqalelo ezintsonkothileyo, isakhiwo sayo ingakhangelwa kwi Internet, njengoko yokupasa kwi leta ngayo nje akunakwenzeka. Omnye Singathi nje starch, ngakumbi ngqo ifomula yayo, iqulathe ezininzi OH-amaqela, nganye kuzo iqhagamshelwe kwi-atom carbon. Abantu abaninzi siphambanise le molecule kunye molecule utywala xa besiva iqela OH, kodwa eneneni kwi molecule kukho S6N10O5 istatshi.

Ukuba ufuna ukubona otashi, ngoko akuyomfuneko ixesha elininzi ixesha elide ukuba bacinge ngayo. asabela esemgangathweni ukuba ubukho wesitatshi kwixesha eliphakathi limi ngolu hlobo: kwi ityhubhu athontsize nje amathontsi ambalwa ayodini. Ukuba isisombululo nangoko siba Sneem, ngokuqinisekileyo unako asayine ityhubhu kwaye uqiniseke ukuba akukho tashi. Ukuba ufuna ukukhangela ukuba indlela abasabela ngayo kwiimeko lomashnih, uthabathe namazambane encinane, lunqamle, uze ngenyameko sokukhetha umbala athontsize amathontsi ambalwa ayodini (ukuba kuthengiswa ezikhemisti ukuba cauterize amanxeba). Emva kwexesha elithile uya ukubona isiphumo ezicacileyo yokusabela esemgangathweni istatshi: neetapile kwindawo apho ayodini kwaba ngcembe iqalisa ukutshaza oluhlaza.

Ngoko ke, ngoku uyazi malunga eninzi wesitatshi (wesitatshi oko kukuthi, ifomula, iimpawu kunye nempendulo quality). Kakade ke, yonke le ngcaciso elapha ngasentla akaphelelanga, kodwa ukuba ukulungele ukuba kuthethwe ngezinto eziphilayo chemistry, ngokuqinisekileyo kuya kukunceda.
