Mgbe starch cleavage kpụrụ a nọmba nke bara uru carbohydrates

Si sụgharịa German, starch pụtara "ike ntụ ọka". Dị ka a mgbagwoju eke polima, starch mejupụtara abụọ Polymers: amylose (25%) na amylopectin (75%). Hibere starch bụ a na-acha ọcha siri ike, ndị na-enweghị uto na isi, fọrọ unyi anaghị agbasa na mmiri oyi ma ọzịza na mmiri ọkụ, si otú enweta Njirimara nke tapawa. Mgbe compressing mkpịsị aka-acha ọcha ntụ ntụ ewepụtarịrị a ji mara creaking. Mgbe anya n'okpuru a microscope, ị pụrụ ịhụ granular Ọdịdị nke starch.

Ná mmalite, mgbe gbawara nke starch a kpụrụ polysaccharide dextrin - a ngwaahịa nke ele mmadụ anya n'ihu hydrolysis nke starch. Dextrins pụrụ inweta site ngwa kpo oku nke starch nwere 10-20% mmiri.

Dị otú ahụ starch cleavage ngwaahịa dị ka dextrin hụrụ mbara ngwa akụ na ụba mba. Dextrins na-eji maka mmepụta nke adhesives eji dị iche iche ọrụ, n'ihi na ihe atụ maka labeling nke containers ma ọ bụ pouches bonding. Na foundry dextrin na-eji maka bonding foundry ájá, na na ìhè ụlọ ọrụ - dịkwuo njupụta nke akwa e ji esiji ákwà. Dextrin hụrụ ngwa ke nri ụlọ ọrụ dị ka isi ụgbọelu nke nri ntụ na e ji esiji ákwà.

Ọzọ, mgbe starch gbawara kpụrụ disaccharide maltose, na mfe carbohydrate glucose.

Maltose mejupụtara abụọ glucose ụmụ irighiri ihe, nwere ma aha ọzọ - malt sugar, nke na-eji na distilling na brewing. Na ọdịdị, hụrụ na nnukwu quantities na pulitere ọka ọka, karịsịa a otutu maltose na ọka bali na rye. Pure maltose emepụta nanị maka laabu nzube obere obere.

Starch bụ a mgbagwoju carbohydrate na na-ẹdude ke ị ga na epupụta nke kasị osisi, ọ bụ a potassium emepụta site osisi dị ka a idobere. Human oriri a ogologo e ji ọka ọgaranya starch, dị ka osikapa, wheat, rye na ndị ọzọ. Ọgaranya na starch na mmasị poteto, na nduku starch bụ ndị kasị ewu ewu na n'ebe nile. Nke a na umi bụ otu n'ime ihe ndị kasị mkpa ngwaahịa maka ahụ mmadụ. Starch mmadụ digestive usoro na-enwe mmetụta enzymes, na disintegration okwu na-amalite mmadụ ọnụ. Human asu nwere enzyme a-amylase ikpe atọghata starch n'ime maltose.

Gastric gburugburu ebe obibi starch cleavage adịghị ime n'ihi na ịnọ nkịtị nke enzyme a-amylase na kislosoderzhaschey gburugburu ebe obibi nke afo. Ọ bụ ya mere a ọma mbụ Lonely nri dị mkpa maka inwekwu mgbaze na absorption site mmadụ starch. Na duodenum n'okpuru nduzi nke a-amylase dị na gastric ihe ọṅụṅụ, mgbe starch emepụta bisaharid maltose cleavage. Na maltose ngwa ngwa mgbari abụọ glucose ụmụ irighiri ihe na etinye obi gị dum site na ahụ mmadụ ruru ka insulin secreted anyịnya, nke dị oké mkpa maka ahụ absorption nke glucose site ahụ. N'elu cleavage nke starch na-emepụta glucose, nke glucose uptake usoro nwayọọ nwayọọ, na-akpata a ịrịba gụnyere ya ná ibu na pancreas usoro, ya mere, na oriri nke ezigbo ichekwa starch na osisi nri nwere ike ije ozi mgbochi nke ọrịa shuga.

N'ihi ya, ikpeazụ ngwaahịa nke starch umuihe - bụ glucose, ndị kasị ama mfe carbohydrate mkpa ezitekwara ụbụrụ anụ ahụ dị iche iche ụmụ mmadụ uru.

Starch na ọtụtụ-eji nri ụlọ ọrụ, ọ bụ otu nke multi-ọtọ inyeaka ngwaahịa. Ihu ọma, ọ na-eji na mejupụtara nke stabilizers na thickeners inye ndị kwekọrọ ekwekọ ngwaahịa udidi na ụdị.
