Incazelo yesithombe
Lesi sithombe sibonisa umfanekiso wesayensi onemininingwane, ocebile ngokubona oqhathanisa futhi uqokomisa izakhiwo zama-molecule kanye nemithombo yemvelo yeVithamini C kanye neVithamini A eceleni. Ukwakheka kuhlelwe ngendlela ehlanzekile, yokuma kwendawo, kuhlukaniswe izingxenye ezimbili eziyinhloko: uhlangothi lwesobunxele olunikezelwe kuVithamini C kanye nohlangothi lwesokudla olunikezelwe kuVithamini A. Zombili izingxenye zihlanganiswe ngokuxhumana okukhanyayo okuthambile, okungabonakali phakathi nendawo, okuphakamisa isihloko esiphelele sokusebenzisana kokudla okunempilo kanye nokuvumelana kwamakhemikhali.
Ngakwesobunxele, ingxenye yeVithamini C iqala ngesihloko esithi "Vitamin C" esibhalwe ngombhalo ogqamile, ophuzi phezulu, okhombisa ngokushesha ukugxila kwale ngxenye yomfanekiso. Ngaphansi kwesihloko, kuboniswa imodeli yamamolekyuli kaVithamini C (i-ascorbic acid) enama-dimensional amathathu. Imodeli isebenzisa ama-sphere anemibala axhunywe ngemigqa emincane, eqondile ukumela ama-athomu nezibopho. Ama-sphere amnyama amelela ama-athomu ekhabhoni, ama-sphere abomvu amelela ama-athomu e-oxygen, kanti ama-sphere amhlophe amelela ama-athomu e-hydrogen. Ukuhlelwa kwala ma-sphere kwakha iqembu elincane, elingajwayelekile kancane, eliveza ngokubonakalayo ubunzima be-molecule ngenkathi lihlala licacile futhi lifinyeleleka kalula ngezinjongo zemfundo.
Ngaphansi ngqo kwemodeli yama-molecule ye-3D, kuboniswa umdwebo wesakhiwo samakhemikhali esinezinhlangothi ezimbili se-Vitamin C. Lo mdwebo usebenzisa umdwebo wamakhemikhali ojwayelekile, okuhlanganisa izinhlamvu, imigqa, kanye nezimpawu ukumela ama-athomu nama-bond. Amaqembu e-hydroxyl abhalwe ngombhalo othi "HO" kanye no-"OH", kanti indandatho ye-lactone iboniswa nge-carbon ephakathi eboshwe kabili kwi-athomu ye-oxygen. Isakhiwo sichazwa ngendlela yombhalo eqondile njenge-"HO-CH₂-C(=O)-C-OH-CH₂-OH" ene-oxygen eyengeziwe eboshwe kabili kwi-carbon ephakathi, kugcizelelwa amaqembu asebenzayo afaka isandla ezimpahleni ze-antioxidant ze-molecule. Umdwebo udwetshwe ngemigqa ecacile namalebula acacile, okwenza ufaneleke kubafundi, othisha, noma ochwepheshe bezempilo abafuna ukuxhumanisa ngokubonakalayo ifomula yama-molecule nokumelwa kwayo kwesakhiwo.
Ngakwesobunxele semidwebo yama-molecule kanye nesakhiwo, umfanekiso uhlanganisa izithombe ezicacile zezithelo ze-citrus ukumela imithombo yemvelo yeVithamini C. Isilayi esikhulu se-orange esinojusi siboniswa ngamaconsi amanzi kanye nokuchaphaza okunamandla, okuphakamisa ukusha kanye namandla. Ngemuva kwesilayi, iqabunga eliluhlaza linezela ukuthinta kwemvelo, okuqinisa ubudlelwano nokudla okuphelele. Ngaphansi kwalokhu, kuboniswa ukuhlelwa kwama-orange aphelele naqoshiwe, azungezwe amabhamuza akhipha umoya anikeza umuzwa wamandla nokukhanya. Amathoni afudumele e-orange kanye nokukhanya okuncane okuzungeze isithombe sezithelo kuqinisa umbono wokuthi iVithamini C ivame ukutholakala kuma-citrus futhi idlala indima ekusekeleni ukusebenza komzimba kanye nempilo iyonke.
Ngakwesokudla kwesithombe, ingxenye yeVithamini A ikhombisa isakhiwo sesobunxele, yakha ukwakheka okulinganiselayo nokulinganayo. Phezulu, isihloko esithi "Vithamini A" sivela ngombhalo ogqamile, ophuzi, ohambisana nesitayela sesihloko seVithamini C futhi sigcina ukuhambisana okubonakalayo. Ngaphansi kwalesi sihloko, kuboniswa imodeli yamamolekyuli kaVithamini A (i-retinol) enama-dimensional amathathu. Njengoba kunjalo ngemodeli yeVithamini C, ama-sphere amnyama amelela ama-athomu ekhabhoni, kuyilapho ama-sphere anombala ophuzi amelela ama-athomu e-hydrogen, kanti i-sphere emhlophe eyodwa ikhombisa i-athomu ye-oxygen. Imodeli yamamolekyuli inde futhi iqondile kakhulu uma iqhathaniswa nesakhiwo seVithamini C esincane, esibonisa isakhiwo esifana neketanga se-retinol. Ama-sphere axhunywe ngemigqa emincane elandela umgogodla we-molecule, eqokomisa iphethini eshintshanayo yezibopho ezilodwa nezimbili.
Ngaphansi kwemodeli ye-3D, kuvezwa umdwebo wesakhiwo samakhemikhali esinezinhlangothi ezimbili se-Vitamin A. Lo mdwebo ukhombisa ukulandelana kwama-athomu e-carbon axhunywe ngokushintshana kwezibopho ezilodwa nezimbili, okugcina eqenjini le-hydroxyl ekugcineni. Isakhiwo sibhalwe ngendlela eqondile njenge-"CH₃-CH=CH-CH₂-CH=CH₂-CH₂-CH₂-CH₃-OH," okubonisa ngokusobala uhlelo lwezibopho ezilodwa kanye neqembu le-OH eliyisiphelo. Umdwebo udwetshwe ngemigqa ebukhali namalebula afundekayo, okwenza kube lula ukulandela ukuqhubeka kochungechunge lwe-carbon nokuqonda uhlobo lwamakhemikhali lwe-retinol.
Ngakwesokudla kakhulu kwesigaba se-Vitamin A, umfanekiso uhlanganisa izithombe zezaqathi ezineziqongo eziluhlaza, ezifanekisela umthombo ovamile wokudla wezinto ezandulela i-Vitamin A njenge-beta-carotene. Izaqathi ziboniswa ngendlela enesitayela kodwa engokoqobo, enemizimba ekhanyayo e-orange namaqabunga aluhlaza okotshani, abekwe ngemuva okukhazimulayo kancane. Eduze kwezaqathi, kuvela isithonjana samehlo aluhlaza, esikhazimulayo kancane, ukuze siphakamise ubudlelwano obaziwayo phakathi kwe-Vitamin A nempilo yamehlo, ikakhulukazi indima yayo ekuboneni nasekugcineni ubuqotho be-retina. Ukuhlanganiswa kwezaqathi nophawu lwamehlo kuqinisa ngokubonakalayo izinzuzo zokusebenza ze-Vitamin A ngendlela eqondakala kalula futhi esekelwe kwesayensi.
Kuzo zombili izigaba, ingemuva linemiphumela yokukhanya okuthambile kanye nokugqama kwesitayela se-bokeh, okudala ubuhle besimanje, bedijithali obuthuthukisa okuqukethwe kwesayensi ngaphandle kokukugqamisa. Imibala ifudumele kakhulu—amawolintshi acebile kanye nophuzi othambile—ilinganiswe yimifino epholile kanye nokukhanya okuluhlaza okwesibhakabhaka okucashile. Le phalethi idala umuzwa wobungqabavu kanye nokuphila kahle, okuhambisana nesihloko samavithamini abalulekile kanye nezindima zawo empilweni yabantu. Indawo ephakathi yesithombe iqukethe ukuxhumana okuncane, okukhazimulayo phakathi kwezingxenye zeVitamin C kanye neVitamin A, okufanekisela umqondo wokuthi amavithamini ahlukene asebenza ndawonye ngaphakathi kwezinhlelo zomzimba eziyinkimbinkimbi ze-biochemical.
Sekukonke, umfanekiso uhlanganisa ukumelwa okunembile kwama-molecule, imidwebo ecacile yamakhemikhali, kanye nemifanekiso evusa inkanuko yemithombo yokudla yemvelo ukudala indaba ebonakalayo ebanzi mayelana neVithamini C neVithamini A. Ifanele ukusetshenziswa ezintweni zemfundo, izethulo ezihlobene nempilo, izihloko zesayensi, noma i-infographics yokudla okunempilo. Isithombe siphumelela ukuvala igebe phakathi kwesayensi yama-molecule engabonakali kanye nokuqonda kokudla kwansuku zonke, okwenza imiqondo itholakale kokubili kochwepheshe kanye nabangebona ochwepheshe.
