Isithombe: Amaqanda anezakhiwo ze-carotenoid

Isithombe sibonisa ukuhlangana okuthakazelisayo kwempilo esekhona yemvelo kanye nokubonwa kwesayensi, siguqula isihloko esilula, esijwayelekile samaqanda sibe indaba ephathelene nokudla, impilo, kanye nobunkimbinkimbi obungabonakali besayensi yezinto eziphilayo. Enkabeni yesehlakalo kukhona itafula lokhuni elidala, okusanhlamvu kwalo okuguquliwe namathoni athulisiwe anikeza isisekelo esifudumele nesithintayo. Kuhlezi phezu kwawo amaqanda amaningana aqhekekile, amagobolondo awo avuleka ngokwanele ukuze embule izikhupha zegolide ezikhanyayo ngaphakathi. Isikhuphasha ngasinye siyabenyezela ngokuvevezela okucebile, indawo yaso ebushelelezi ebonisa ukukhanya okuthambile, okuhlukanisiwe. Ukuhlangana phakathi kokuthungwa kwe-rustic yokhuni, ubuthakathaka be-matte bamagobolondo, namandla akhazimulayo wezikhupha kudala ukuvumelana okubonakalayo okusheshayo, ukulinganisa ubulula nokunotha. Ukukhanya, okungokwemvelo nokungaphansi, kwengeza ukujula ngokugqamisa amajika amagobolondo kanye nokukhanya okucwebezelayo kwezikhupha, kumema umbukeli ukuthi agxile ekukhazimuleni kwawo.

Nokho, ngalé kwalobu buhle bemvelo, ukuqanjwa kuhlanganisa nolunye ungqimba lwencazelo ngemifanekiso yesayensi ephakeme kakhulu. Izinhlobo zamangqamuzana agqamile zintanta ngenhla noma eduze kwamaqanda, amafomu awo agqamile abonakala ngokuluhlaza okwesibhakabhaka, amawolintshi avuthayo, nokuphuzi okucebile. Lezi zakhiwo ezingabonakali, ezinezinhlangothi ezintathu ziyimifanekiso ye-lutein ne-zeaxanthin, i-carotenoid ebolekisa izikhupha zamaqanda umbala wazo wegolide futhi zaziwa ngezinzuzo zazo zezempilo, ikakhulukazi ekusekeleni impilo yamehlo kanye nokunciphisa ingcindezi ye-oxidative. Ama-molecule, nama-node awo akhazimulayo kanye nokuxhumana kwamagatsha, afana nendawo yonke encane, ephakamisa imihlaba efihliwe phakathi nokudla okulula kakhulu. Ukubekwa kwazo eduze kwezikhupha eziqhekekile kufiphalisa umngcele phakathi kwempilo esekhona yemvelo kanye nomdwebo wesayensi, kuguqula isehlakalo sibe ukuzindla okuyingxube kukho kokubili ibhayoloji nobuciko.

Lokhu kuhlanganisa kwakha inkhulumomphendvulwano phakathi kokubonakalayo nokungabonakali, okubambekayo kanye nomqondo. Amagobolondo aqhephukile afanekisela ubuthakathaka, ukondleka, kanye neziqalo, kuyilapho izikhupha zikhipha amandla nesithembiso. Ukuwamboza ngezakhiwo zamangqamuzana kudonsela ukunakekela ebunkingeni obungabonakali obungaphakathi kwalokhu kudla kwansuku zonke, kusikhumbuza ukuthi ukondliwa akukhona nje ukunambitheka noma ukudla, kodwa kumayelana namakhemikhali nezinhlanganisela ezibalulekile ezisekela ukuphila. Amangqamuzana ahamba cishe njengamaqoqo ezinkanyezi noma amafomu ezwe, imibala yawo ekhanyayo enanela imibala yezikhupha ngokwazo, eqinisa ukuhlobana okuseduze phakathi kwalokho okubonakala ngeso nalokho okusebenza ezingeni elincane kakhulu.

Ithebula le-rustic kanye nokukhanya kwemvelo kugxilisa ukwakheka emhlabeni wangempela, wansuku zonke, amakhishi avusa amadlingozi, amapulazi, kanye nesenzo esingapheli sokuqoqa nokulungisa ukudla. Ngesikhathi esifanayo, imbondela ye-molecular iphakamisa isithombe siyise endaweni yesayensi, ebonisa amalabhorethri, ucwaningo, nophenyo olujulile oluveza ukusebenza okufihliwe kokudla okunomsoco. Lokhu kungezwani phakathi kokulula nokuba yinkimbinkimbi, okujwayelekile nokungajwayelekile, yikho okwenza isimo sibe nokuzwakala kwaso. Iguqula iqanda elithobekile libe uphawu lwakho kokubili isiko lamasiko kanye nesayensi esezingeni eliphezulu, lihlanganisa imihlaba emibili evame ukubonakala njengehlukene kodwa lapha ehlala ndawonye ngokuvumelana.

Isimo esivelayo singesokulinganisela, ubungqabavu, nokwazisa. Amaqanda, ahunyushwa ngobumnene nangemfudumalo, akhuluma ngobuhle bemvelo, kuyilapho imidwebo yamangqamuzana yethula ukunemba, ulwazi, nokusungula izinto ezintsha. Ngokubambisana, bakha umbono wokudla hhayi nje njengokudla, kodwa njengokuhlangana kobuciko, isayensi nempilo. Izikhupha zegolide zihlanganisa inala yemvelo, kuyilapho izakhiwo ze-carotenoid ezihamba eduze ziveza izipho ezifihliwe zemvelo ezivulwe ukuqonda kwesayensi. Kungumkhosi wokugubha ukuthi izimpilo zethu zixhumene ngokujule kangakanani nobulula bokudla kwemvelo kanye namakhemikhali ayinkimbinkimbi asisekelayo.

Ekugcineni, isithombe sizwakala njengempilo engokomfanekiso yenkathi yesimanje. Njengoba nje ukuphila okungokwesiko kwake kwagqamisa inala yesivuno noma ukunotha kwempilo yasekhaya, lokhu kwakheka kwesikhathi samanje kugcizelela umshado wesiko nesayensi. Amaqanda aqhephukile etafuleni le-rustic asikhumbuza imvelaphi kanye nokulula, kuyilapho ama-molecule aphilayo esikhumbuza inqubekelaphambili nokutholwa. Ndawonye, basicela ukuba sicabange ngokuvumelana phakathi kwalokho esikubonayo nalokho okungaphansi, basikhuthaza ukuba singazisi nje kuphela ubuhle bezinhlobo zemvelo kodwa nezakhiwo ezingabonakali ezizenza zibaluleke kangaka enhlalakahleni yethu.
