Yiziphi carbohydrate?

Kuyinto imfihlo ukuthi iyiphi, ngisho ukudla gastronomically eyinkimbinkimbi futhi exotic kungenziwa ukubola zibe izakhi zawo ingxenye, igama elivamile okuyinto macronutrients. Zibhaleni phansi esifushane kakhulu futhi eyaziwayo:

• amaprotheni;
• amafutha;
• carbohydrate.

Ngaphezu kwalokho, umkhiqizo ngamunye ngezabelo ezahlukene yakhiwa amanzi, amavithamini kanye izakhi mkhondo. Kuyinto kule yamila umbono we ukudla amuncwa wumzimba. ukudla ngamunye eyanele, kuye ngokuthi ukwakheka iphesenti macronutrients, ngokwanele kunemiphumela ehlukile ezinganeni phezu kwempilo yabantu. Into wukuthi "isitini 'ngalunye lwenza umsebenzi walo futhi ufeze izinjongo ezihlukahlukene. Lesi sihloko Kuzoxoxwa ngani kabanzi ukudla okumahhadla nomoya-umsebenzi wabo.

Ngokuvamile imikhiqizo nge high amandla value elihlobene ne-calories. Okusanda imfashini ukuba ngaphandle kusukela ekudleni ukudla carbohydrate-equkethe, njengoba kunenkolelo ukuthi indlela kilojoule eyanele kuyehla. Ukuthungatha Iqiniso E-lendlela, yebo. Ikakhulukazi uma umsubathi okhokhelwayo. Nokho, izinto zokuqala kuqala.

Ngakho lokho carbohydrate?

Umsebenzi oyinhloko lezi macronutrients - amandla. Njengoba uhlobo kwebhethri umzimba, ama-carbohydrate ukusiza ukusekela zokuziphilisa, ngenxa zamandla cleavage yabo Kwenziwa umsebenzi wonke zomzimba. Kuyaziwa ukuthi cleavage ezithela 1 g carbohydrate 4 umzimba kcal ezaziwayo. Inani elifanayo enikeziwe emzimbeni nasesikhathini cleavage 1 g fat. Nokho, wokuqhekeka amaketanga olude monosaccharides nemikhiqizo wachitha amandla ingasaphathwa, ngakhoke umzimba kulula ukuba "zisishise" 1 g carbohydrate, 1 g fat kuka eceleni.

Ama-carbohydrate, kuncike ukwakheka kwama-molecule noma, ngamanye amazwi, ubude iketango yamangqamuzana, zihlukaniswe elula eziyinkimbinkimbi.

Yiziphi carbohydrate elula?

Isayensi, kukhona izinhlobo ezimbili monosaccharides futhi disaccharides. Phakathi monosaccharides ezivamile futhi zenzeka ifomu khulula ngokwemvelo - glucose ne fructose. Atholakala fresh ayo, izithelo. Uchungechunge monosaccharides, njengoba kungabonakala isihloko - elula kakhulu, okuyinto enomthelela ukumuncwa kwabo okusheshayo umzimba. Formula disaccharides (sucrose, maltose, lactose) - chain izinsalela of monosaccharides eziningana. Disaccharides eziqukethwe imikhiqizo yobisi (lactose), umoba (sucrose) futhi kwezinye okusanhlamvu (maltose).

Yiziphi -carbohydrate ayinkimbinkimbi?

Okunye -polisaharidy igama yabo, akhiwa izinkulungwane eziningana izinsalela monosaccharide, okungukuthi, ube nomgexo omude futhi ekhelini engaphezu kuka carbohydrate elula. Laba bameleli be-esaziwa kakhulu leli qembu Uyi pectin, i-cellulose, isitashi glycogen. Carbohydrate iqembu njengoba injalo sasekuqaleni amuncwa wumzimba. Yehlukanise wabayisa ifomu elula kalula digestible kudinga abalulekile izindleko zamandla. Ezinye izinhlobo (fibre) is hhayi ugxile nhlobo. Kuyasiza ukuzisebenzisa njengoba stimulator we emathunjini ipheshana umsebenzi nokuhlanzwa ubuthi. Ngaphezu kwalokho, glycogen, njengemoto zokwakha ukuze umzimba (isibindi, kwemisipha).

Uma sithole lokho carbohydrate, kunengqondo ukubuyela umbuzo usizo emzimbeni. Kusobala ukuthi kulawo mafomu eziyinkimbinkimbi ziwusizo ngisho okudingwa ngumzimba ukuze isebenze kahle ngenxa yokuthi zifeza ukwakhiwa kanye umsebenzi umsoco.

Ngenxa yokuthi polysaccharides uhlukanise amandla okusezingeni eliphezulu ukusetshenziswa futhi kugaywe kancane kakhulu, basuke neze elondolozwe njenge amafutha ngoba abanawo isikhathi. Monosaccharides, kunalokho, ukufunda ngokushesha kakhulu futhi esebenza ngokuqondile egazini, okubangela lokho okubizwa ngokuthi "ama-carbohydrate eqa" ukuthi is ngqo ukwandisa amandla. Ukusebenzisa kwabo ngokweqile, ngokungabi bikho okusezingeni eliphezulu kwamandla, okuholela ukucutshungulwa ukudla okumahhadla nomoya-ekuqongeleleni yabo ngesimo amafutha.

Lokho carbohydrate, odinga ukukwazi ukwakha umsoco ofanele. Ukusetshenziswa izimo ezilula neziyinkimbinkimbi ezidingekayo ukuze umzimba, kungenjalo izinqubo (kuhlanganise engqondo) okwehlisa, kwenzeka ukucobeka kanye nokunganaki.
