I-molecule yamanzi - isipho esihle bemvelo

I-molecule yamanzi - ekhuthaza izici elula bemvelo, kodwa umsebenzi walo kunzima overestimate. Amanzi - ngesisekelo umzimba wazo zonke izinto eziphilayo, kumuntu ke imayelana ayisikhombisa amaphesenti. Zonke zamakhemikhali zenzeka emzimbeni, futhi, sibonga amanzi. Ngakho, lifundisani ngale molecule ephawulekayo?

Isakhiwo molecule yamanzi ezinzima elula. Isakhiwo engqamuzaneni kuhlanganisa ama-athomu amathathu - eyodwa yomoya-mpilo futhi ezimbili ze-hydrogen. O lisho umoya-mpilo, ne-hydrogen N. chemical ifomula okhonjiswe - H2O. Njengazo zonke namanye amangqamuzana, amanzi kwenkokhelo. Amacala kuthiwa Ukuboshelwa zisakazwe, ngakho-molecule yamanzi has izigxobo ezimbili - emihle nemibi. I-engeli phakathi amangqamuzana ingase yehluke kuye ngesistimu isimo amanzi, isibonelo esimweni ice ke unwetshiwe. Inkolelo yokuthi amanzi-molecule has ama-athomu ye-hydrogen ngakolunye uhlangothi, abacwaningi wavakashela iminyaka cishe eyikhulu edlule. EyiNgisi Bernal ukuthi indlela elula ukwakha umfuziselo molecule yamanzi iketanga, lapho izinhlangothi, babefika beme hydrogen ne-oksijini phakathi. Nokho, uma i-molecule yamanzi kungaba kagesi hlangothi. Lesi siphetho kungenzeka bagomela ngokuthi molecule amanzi has a athomu ye-hydrogen ohlangothini olufanayo, elibangela isimo salo kagesi.

Usayizi molecule amanzi futhi abacwaningi nesithakazelo. Kuye kwatholakala ukuthi ubukhulu bayo - emithathu eshumini a i-nanometer, futhi isiqalo lokususa amandla lesishiyagalolunye izindlela. Okungukuthi, ngemva iphuzu kuwufanele amaqanda ayisishiyagalolunye. usayizi yamangqamuzana okunjalo kuyivumela ukuba mobile, ushintshe yabo Izakhiwo futhi baxhumane izinto ezihlukahlukene zamakhemikhali.

Ukucwaninga kososayensi kuveza ukuthi ukuphila kwaqala emanzini. Ngokusebenzisa imithombo yamandla ezahlukene organic compounds Ayekulungele laboratories - amaprotheni, amino acid, nucleosides. Konke ukucwaningwa zazenziwa ukuze mpilo cha, futhi lokho ngenxa yamandla Ukudlula zamagama. Kuyaziwa ukuthi amanzi esikwenzile lokhu, futhi ngenxa yalokho uvame ukubizwa kanjalo ikwazi ukuziphilisa.

Izakhiwo lamanzi elisetshenziswa ekwelapheni izifo ezihlukahlukene. Indaba ezithakazelisayo uDkt Batmanghelidj, ngubani kwasindisa ukuphila kwakhe ngosizo ... amanzi. Okwesikhathi esithile ayenakho ukuze uhlale ensimini ka-Iran, lapho ngaleso sikhathi wabaholi babemagange amandla. Eshanela kubantu ejele endleleni yabo, baba kancane sokulungisa owenza lokho nokuthi kungalimaza umbuso wabo. Ngaphansi ihlazo ishayise Dr. Batmanghelidj. impahla yakhe Kwadliwa, futhi Fereydoon waboshwa. Isikhathi ayichitha ejele akudluliselwa isipho usosayensi - Wenza ucwaningo, wabe usuthola ukuthi amanzi has okwelapha futhi kuyasiza ukwelapha izifo ezithile, njenge isilonda esiswini kanye isilonda duodenal. Isiguli kuleli jele uhlushwa lesi sifo, kodwa akukho izidakamizwa noma ezinye izindlela ukuze usize wawungewona kuye. Khona-ke udokotela ebekiwe imithi itholakala kuphela - ezimbili izingilazi zamanzi. Ngemva kwesikhashana ubuhlungu limukile, isiguli ngingcono kakhulu. Labanye isikhathi usosayensi ejele anikezelwe cwaninga izakhiwo amanzi.

Ngosuku sinqumo Batmanghelidj eseqedile ukuloba i-athikili mayelana okwelapha amanzi. Wayazi ukuthi enikwa isigwebo sokufa, futhi ngemva sinqumo wanika indaba yakhe nejaji. Cabanga ukumangala lapho umahluleli wasixolela usosayensi wamnika imvume yokwenza ucwaningo lwazo ku. Kukho konke ukuphila kwakhe, Dr. vodopitie igqugquzela indlela ephumelelayo for izifo eziningi. Lokho kungenxa yokuthi amanzi agciniwe ngokufa usosayensi othile.

Ukuphila komuntu ngokuqhubekayo exhunywe kwi amanzi. i-molecule Fragile yamanzi, Nokho, okuyinto, has izindawo eziningi ewusizo, esisinikezwa imvelo, futhi sinesibopho ukuvikela izinsiza amanzi le planethi, ngoba amanzi - lokho kungukuphila.
