I-SUCROSE: INCAZELO YENTO, INDIMA EMZIMBENI

Send

Ososayensi bathole ukuthi i-sucrose iyingxenye ebalulekile yazo zonke izitshalo. Le nto itholakala ngamanani amakhulu kumabhiya omoba noshukela. Indima yalo mkhiqizo inkulu kakhulu ekudleni komuntu ngamunye.

I-Sucrose ingeqembu le-disaccharides (lifakwe kusigaba se-oligosaccharides). Ngaphansi kwethonya le-enzyme yayo noma i-acid, i-sucrose ivele ibe yi-fructose (ushukela wezithelo) noshukela, okwenza iningi lama-polysaccharides.

Ngamanye amagama, ama-molecule we-sucrose akhiwa ngezinsalela ze-D-glucose ne-D-fructose.

Umkhiqizo omkhulu otholakala, osebenza njengomthombo oyinhloko we-sucrose, ushukela ojwayelekile, othengiswa kunoma yisiphi isitolo sezitolo. Isayensi yamakhemikhali ibhekisa kumolekyuli ye-sucrose, okuyi-isomer, kanje: C₁₂N₂₂Hhawu₁₁.

Ukusebenzisana kwe-sucrose namanzi (i-hydrolysis)

Nge₁₂N₂₂Hhawu₁₁ + H₂O → C₆N₁₂Hhawu₆ + C₆N₁₂Hhawu₆

I-Sucrose ibhekwa njengebaluleke kakhulu kuma-disaccharides. Ukusuka ku-equation kuyabonakala ukuthi i-hydrolysis ye-sucrose iholela ekwakhekeni kwe-fructose noshukela.

Izimo zamamolekyuli zalezi zinto ziyefana, kepha ezakhiwayo zihluke ngokuphelele.

I-Fructose - CH₂ - CH - CH - CH -C - CH₂ .

IGlucose - CH₂(OH) - (SNON)₄-DREAM.

I-Sucrose nezakhiwo zayo ezibonakalayo

I-Sucrose ingilazi elimnandi, elingenamibala elinyibilika kakhulu emanzini. Indawo encibilikayo ye-sucrose ingu-160 ° C. Lapho i-sucrose encibilikisiwe iqina, kwakhiwa inqwaba yokubonisa okusobala - i-caramel.

Izakhiwo ze-sucrose:

Le yi-disaccharide ebaluleke kakhulu.
Ayisebenzi kuma-aldehydes.
Lapho ukufuthelana no-Ag₂O (isixazululo se-ammonia) asinikezi umphumela wesibuko sesiliva.
Lapho kushiswa nge-Cu (OH)₂(i-iron hydroxide) i-oxide ebomvu ayiveli.
Uma ubilisa isixazululo se-sucrose ngamaconsi ambalwa we-hydrochloric noma i-sulfuric acid, bese uyihlukanisa nganoma iyiphi i-alkali, bese ushisa ikhambi elibangelwa yi-Cu (OH) 2, i-red precipitate ingabonakala.

Ukwakheka

Ukwakheka kwe-sucrose, njengoba uyazi, kufaka i-fructose noshukela, ngokunembile, izinsalela zawo. Zombili lezi zinto zixhumene kakhulu. Kwama-isomers ane-formula yamaseli C₁₂N₂₂Hhawu₁₁, udinga ukugqamisa lokhu:

ushukela wobisi (i-lactose);
ushukela we-malt (maltose).

Ukuthi sucrose kuthinta kanjani umzimba womuntu

Kubalulekile! Umuthi uhlinzeka umzimba womuntu ngokuhlinzekwa okugcwele kwamandla, okudingekayo ekusebenzeni kwazo zonke izitho nezinhlelo.

I-Sucrose ivuselela imisebenzi yokuvikela isibindi, ithuthukise umsebenzi wobuchopho, ivikela umuntu ekuchayweni kwezinto ezinobuthi.

Ixhasa umsebenzi wamaseli wezinzwa nemisipha ethambile.

Ngalesi sizathu, isici sithathwa njengesibaluleke kakhulu phakathi kwalabo abatholakala cishe kuyo yonke imikhiqizo yokudla.

Uma umzimba womuntu unele ku-sucrose, kuzabonakala lezi zimpawu ezilandelayo:

ukulahlekelwa amandla;
ukuntuleka kwamandla;
ukunganaki
ukungahambi kahle;
ukudangala

Ngaphezu kwalokho, impilo ingakhula kancane, ngakho-ke udinga ukuguqula inani le-sucrose emzimbeni ngesikhathi.

Amazinga we-sucrose aphezulu nawo ayingozi kakhulu:

isifo sikashukela mellitus;
ukulunywa ngofuzo;
i-candidiasis;
izinqubo zokuvuvukala emgodini womlomo;
isifo se-periodontal;
ukukhuluphala;
amasenti.

Uma ubuchopho bomuntu bugcwala kakhulu ngomsebenzi wengqondo osebenzayo noma umzimba uthintekile ngezinto ezinobuthi, isidingo se-sucrose sanda kakhulu. Ngakolunye uhlangothi, lesi sidingo sincishiswa uma umuntu ekhuluphele noma ephethwe yisifo sikashukela.

Ukuthi i-glucose ne-fructose kuthinta kanjani umzimba womuntu

Njengomphumela we-hydrolysis we-sucrose, i-glucose ne-fructose kuyakhiwa. Yiziphi izimfanelo eziphambili zazo zombili lezi zinto, futhi zikuthinta kanjani impilo yomuntu?

I-Fructose uhlobo lwesimolekyuli sikashukela futhi itholakala ngobuningi bezithelo ezintsha, ibanikeza ubumnandi. Kulokhu, kungabhekwa ukuthi i-fructose ilusizo kakhulu, ngoba iyisakhi semvelo. I-Fructose, enenkomba ye-glycemic ephansi, ayikhulisi ukugcwala koshukela egazini.

Umkhiqizo ngokwawo umnandi kakhulu, kepha ufakwa ekwakhekeni kwezithelo ezaziwayo kuphela ngamanani amancane. Ngakho-ke, kuphela ushukela omncane kakhulu ongena emzimbeni, bese ucutshungulwa ngokushesha.

Kodwa-ke, inani elikhulu le-fructose akufanele lingezwe ekudleni. Ukusetshenziswa kwalo okungenangqondo kungakucasula:

ukukhuluphala kwesibindi;
ukuqina kwesibindi - i-cirrhosis;
ukukhuluphala
isifo senhliziyo
isifo sikashukela mellitus;
gout
ukuguga kwesikhumba ngaphambi kwesikhathi.

Abaphenyi baphetha ngokuthi, ngokungafani noshukela, i-fructose ibangela izimpawu zokuguga ngokushesha okukhulu. Ukukhuluma ngokufakwa esikhundleni salokhu kulokhu akunangqondo nhlobo.

Ngokusekelwe kokushiwo ngenhla, singaphetha ngokuthi ukusetshenziswa kwezithelo ngamanani afanele omzimba womuntu kulusizo kakhulu, ngoba kufaka nenani elincane le-fructose.

Kodwa i-fructose egxile kunconywa ukuthi igwenywe, ngoba lo mkhiqizo ungaholela ekwakhiweni kwezifo ezahlukahlukene. Futhi kufanele wazi ukuthi i-fructose ithathwa kanjani kushukela.

Njenge-fructose, ushukela luhlobo loshukela kanye nefomu elivame kakhulu le-carbohydrate. Umkhiqizo utholakala kuma-starches. I-glucose ihlinzeka umzimba womuntu, ikakhulukazi ubuchopho bakhe, ngokuhlinzeka kwamandla isikhathi eside, kepha ikhulisa kakhulu ushukela egazini.

Nakani! Ngokusetshenziswa okujwayelekile kokudla okwenziwa yinkimbinkimbi yokudla okulula ama-starches (ufulawa omhlophe, ilayisi elimhlophe), ushukela wegazi uzokwenyuka kakhulu.
