Incazelo yesithombe
Lesi sithombe sibonisa umfanekiso wedijithali we-2D onemininingwane, onesinqumo esiphezulu wesakhiwo sama-molecule se-allicin, inhlanganisela evelele ye-organosulfur, ebekwe ngemuva kwesizinda esithambile, esinesihloko sesayensi. Ukwakheka kusesimweni sendawo, kugxilwe kakhulu emelelweni le-molecule ye-allicin enemibala egqamile. Phezulu kwesithombe, igama elithi "Allicin" livela ngezinhlamvu ezinkulu, ezinesibindi, ezimnyama, ezinemisho, ezikhomba ngokucacile inhlanganisela futhi zinikeza umdwebo umuzwa ocacile kanye nenhloso ngokushesha.
Ingemuva linomphetho obushelelezi oguquka usuka koluhlaza okotshani olukhanyayo, olusha emaphethelweni aphezulu uye kophuzi oluhlaza okotshani ophansi. Lo mphetho uveza ubudlelwano nezitshalo kanye ne-chemistry yemvelo, okusikisela kancane ukuthi i-allicin ivela kugalikhi ngaphandle kokubonisa noma yisiphi isithombe sangempela sesitshalo. Umphetho uhlanzekile futhi awubonakali, oqinisekisa ukuthi umdwebo wama-molecule uhlala uyinto eyinhloko ebhekisiswayo. Izimo ezingenalutho, ezicacile kancane kanye nezimpawu zama-molecule ezingabonakali zisakazeke kuyo yonke ingemuva, zengeza ukujula kanye nobuhle besayensi besimanje. Lezi zinhlobo zifiphele futhi zenziwe ngobumnene, ngakho azincintisani nesakhiwo esiyinhloko kodwa kunalokho zakha umuzwa womongo, njengokungathi i-molecule isendaweni ebanzi yamakhemikhali.
Ephakathi kwesithombe, i-molecule ye-allicin iboniswa kusetshenziswa imodeli yebhola nenduku. I-athomu ngayinye imelelwa yimbulunga enemibala, futhi izibopho phakathi kwama-athomu ziboniswa njengemigqa eqinile noma eqhekekile. Ngakwesobunxele se-molecule, kuboniswe iqembu le-methyl. Leli qembu lakhiwe yimbulunga emnyama ebhalwe ukuthi "H₃C," emele i-athomu yekhabhoni ehlanganiswe nama-athomu amathathu e-hydrogen. Ilebula licacile futhi liyafundeka, kusetshenziswa ifonti elula, engena-serif ehambisana nethoni yesayensi iyonke yomdwebo. Leli qembu le-methyl lixhunywe ngesibopho esisodwa ku-athomu ye-oxygen, eboniswa njengembulunga ebomvu. Umbala obomvu uhlukanisa ngokushesha i-oxygen kwamanye ama-athomu, okwenza kube lula ukuhlaziya isakhiwo ngokubonakalayo.
I-athomu ye-oksijini ngakwesobunxele ihlanganiswe kabili ne-athomu yesulfure, emelelwa yi-sphere ephuzi. I-bond ephindwe kabili iboniswa njengemigqa emibili ehambisanayo, igcizelela uhlobo lwe-bond futhi isiza ababukeli ukuqonda ukuxhumana ngaphakathi kwe-molecule. Le athomu yesulfure yokuqala ihlanganiswa eyodwa ne-athomu yesulfure yesibili, nayo eboniswa njenge-sphere ephuzi. Phakathi kwala ma-athomu amabili e-sulfure, kudwetshwa umugqa onamachashazi, ofanekisela ukuxhumana kwe-disulfide noma uhlobo olukhethekile lokuxhumana oluphakathi kwe-chemistry yamakhemikhali e-organosulfur. Ukusetshenziswa komugqa onamachashazi kuhlukanisa lesi sibopho nezibopho ezijwayelekile ezi-single nezi-double, kufaka ngokubonakalayo ulwazi olwengeziwe lwamakhemikhali kumdwebo.
Uma isiya ohlangothini lwesokudla lwe-molecule, i-athomu yesibili yesibabule ixhunywa kwenye i-athomu ye-oxygen, iphinde iboniswe njenge-sphere ebomvu ebhalwe ngo-"O." Le athomu ye-oxygen ixhunywa ngesibopho esisodwa, futhi ukubekwa kwayo ohlangothini lwesokudla kakhulu lwesifunda se-sulfur esimaphakathi kusiza ukulinganisela ukwakheka. Ngaphezu kwale-oxygen, i-athomu yesibili yesibabule ixhunywa neqembu le-ethyl. Leli qembu le-ethyl liboniswa njengochungechunge lwezimbulunga ezimbili ezimnyama ezimele ama-athomu e-carbon, ngayinye ixhunywe kuzimbulunga ezimhlophe ezimele ama-athomu e-hydrogen. I-carbon yokuqala kulolu chungechunge ixhunywa ezimbulungeni ezimbili ezimhlophe, kuyilapho i-carbon yesibili ixhunywa kuzimbulunga ezimhlophe, idlulisa ngokubonakalayo ukusatshalaliswa kwe-hydrogen eceleni komgogodla we-carbon. Izimbulunga ezimhlophe zincane kunezimbulunga ezinemibala yama-heteroatoms, okwenza umdwebo uqondane futhi kube lula ukuwuchaza.
Ngaphansi komfanekiso wama-molecule ophakathi, kukhona ukumelwa kombhalo wefomula yamakhemikhali kanye negama le-allicin. Ifomula ibhalwe ngokuthi "CH₃–S–S–CH₂–CH=CH–O" ngombhalo ogqamile, kusetshenziswa ifonti ecacile ekhombisa isitayela sesihloko phezulu. Le fomula inikeza ukumelwa okuqondile kokuxhumana kwe-molecule, okuhambisana nomdwebo webhola nenduku ngenhla. Ngaphansi kwefomula, embhalweni omncane, obhalwe ngo-italic, kuvela igama elithi "Diallyl thiosulfinate." Leli gama lesibili liqinisa ubunikazi be-compound futhi lethula amagama ayo amakhemikhali asemthethweni kakhulu. Isitayela esi-italic sihlukanisa ngokungabonakali igama kwifomula, kuyilapho usayizi omncane uqinisekisa ukuthi awudluli ulwazi oluyinhloko lwesakhiwo.
Lonke umdwebo udwetshwe ngemigqa ecacile kanye nomthunzi obushelelezi, okunikeza ama-sphere ukubukeka okuncane okunezinhlangothi ezintathu ngaphandle kokuwenza abe ngokoqobo ngokweqile. Ukukhanya okuthambile kuzungeze isakhiwo sama-molecule esiphakathi, kusigqamisa kancane ngemuva futhi kudonsele iso lombukeli enkabeni yesithombe. Lokhu kukhanya kuncane futhi akufihli noma yimaphi amalebula noma izibopho; kunalokho, kuthuthukisa umbono we-molecule njengendawo ebalulekile yokwakheka.
Sekukonke, isithombe sihlanganisa ukucaca, ukunemba kwesayensi, kanye nokukhanga kobuhle. Ukusetshenziswa ngokucophelela kokubhala imibala—omnyama wekhabhoni, omhlophe we-hydrogen, obomvu we-oxygen, kanye nophuzi we-sulfur—kuvumela ababukeli ukuthi bahlukanise ngokushesha izinhlobo ezahlukene zama-athomu. Izibopho zimelelwa njalo, ngemigqa eyodwa, emibili, nenemigqa emfushane eveza uhlobo lokuxhumana ngakunye. Izinto zangemuva, kufaka phakathi i-gradient kanye ne-faint molecular motifs, zinikeza umuzwa wokujula kanye nomongo ngaphandle kokuphazamisa umdwebo oyinhloko. Amalebula ombhalo aphezulu naphansi afaka uhlaka lomfanekiso, okwenza ufanelekele izinto zemfundo, izethulo zesayensi, noma okuqukethwe okuchazayo mayelana ne-allicin kanye nama-organosulfur ahlobene nawo.
Ngamafuphi, lo mdwebo wesakhiwo sama-molecule unikeza ukumelwa okukhangayo nokunolwazi kwe-allicin. Uqokomisa amaqembu abalulekile asebenzayo, ukuxhumana kwe-disulfide, kanye nokuxhumana okuphelele kwe-molecule, kuyilapho izakhi zomklamo ezizungezile ziqinisa ubuntu bayo besayensi. Isithombe sinembile futhi sifinyeleleka kalula, okwenza ulwazi oluyinkimbinkimbi lwamakhemikhali lutholakale kubafundi, abacwaningi, kanye nababukeli abanelukuluku ngokufanayo.
