Qhov sib txawv tseem ceeb ntawm gliadin thiab glutenin yog gliadin yog ib hom gluten uas yog dej-insoluble, whereas glutenin yog ib hom gluten uas yog dej-soluble.

Gluten yog ib qho tshuaj lom neeg uas peb tuaj yeem pom hauv cov kab mob muaj sia. Piv txwv li, peb tuaj yeem pom qhov sib xyaw no yog cov khoom xws li cov hmoov nplej. Muaj ob hom gluten, hu ua gliadin thiab glutenin. Qhov sib txawv ntawm gliadin thiab glutenin yog lawv cov dej solubility.

Gliadin yog dab tsi?

Gliadin yog ib hom gluten protein uas yog insoluble hauv dej. Cov chav kawm ntawm cov protein no muaj nyob rau hauv cov nplej thiab ntau lwm cov cereals hauv genus Triticum. Gliadin yog ib qho tseem ceeb ntawm cov qhob cij nws lub peev xwm nce siab thaum lub sij hawm ci.

Daim duab 01: Tus qauv ntawm Gliadin

Tsis tas li ntawd, muaj peb yam tseem ceeb ntawm gliadins li alpha-gliadin, gamma gliadin thiab omega gliadin. Peb tuaj yeem cais thiab paub qhov txawv ntawm peb hom no nyob ntawm cov amino acid sequences hauv N-terminal ntawm cysteine domain. Alpha gliadin Cheebtsam yog soluble nyob rau hauv cawv muaj ib tug tsawg concentration. Gamma gliadin Cheebtsam yog suav hais tias yog cov poj koob yawm txwv daim ntawv ntawm cysteine-nplua nuj gliadin, muaj tsuas yog intrachain disulfide txuas hniav. Omega gliadin Cheebtsam, ntawm qhov tod tes, yog soluble hauv acidic acetonitrile Cheebtsam uas muaj feem pua.

Tsis tas li ntawd, peb tuaj yeem ua lub npe gliadins ua cov proteins uas tsis zoo hauv lub cev, uas txhais tau hais tias cov tebchaw no tau hloov pauv tsis tu ncua, uas ua rau nws nyuaj rau kev kawm lawv. Raws li kev tshawb fawb tshawb fawb tsis ntev los no, cov qauv protein ntawm gliadin ua raws li cov duab elliptical.

Dhau li, tsis zoo li lwm hom gluten, gliadins tshwm sim hauv lawv cov qauv monomeric hauv cov hlwb. Txawm li cas los xij, cov gliadin tebchaw no tsis tuaj yeem tsim cov qauv polymeric hauv cov hlwb vim lawv cov kev sib cuam tshuam hydrophobic. Peb tuaj yeem hu ua gliadins ua prolamins uas tuaj yeem sib cais nyob ntawm qhov kev txav ntawm electrophoretic thiab isoelectric tsom. Ntxiv mus, gliadin molecules tuaj yeem hla lub plab hnyuv los ntawm txoj kev thauj mus los.

Glutenin yog dab tsi?

Glutenin yog ib hom gluten uas yog insoluble hauv dej. Nws yog ib qho tseem ceeb ntawm cov protein nyob hauv cov hmoov nplej (kwv yees li 47% ntawm cov ntsiab lus protein hauv cov hmoov nplej). Glutenin Cheebtsam yog cov protein aggregates uas muaj cov subunits nrog lub siab molecular loj thiab subunits nrog ib tug tsawg molecular loj. Cov subunits no ruaj khov los ntawm kev sib txuas ntawm cov disulfide bonds, hydrophobic kev sib cuam tshuam thiab lwm yam quab yuam ntawm cov molecules. Ntxiv mus, qhov sib xyaw no yog lub luag haujlwm rau lub zog thiab elasticity ntawm lub khob noom cookie ua los ntawm cov hmoov nplej. Hauv cov txheej txheem ntawm kev ua khob cij, qhov zoo ntawm lub khob cij yog nyob ntawm tus naj npawb thiab muaj pes tsawg leeg ntawm siab molecular hnyav glutenin subunits.

Tsis tas li ntawd, tsis zoo li gliadins, lwm hom gluten loj, glutenin tshwm sim hauv cov nroj tsuag hauv daim ntawv polymeric. Cov qauv txuas txuas ntxiv ntawm cov polymers ntawm glutenin cov ntaub ntawv vim yog disulfide bonds.

Qhov txawv ntawm Gliadin thiab Glutenin yog dab tsi?

Gliadin thiab glutenin yog ob hom gluten loj. Qhov sib txawv tseem ceeb ntawm gliadin thiab glutenin yog gliadin yog ib hom gluten uas yog dej-insoluble, whereas glutenin yog ib hom gluten uas yog dej-soluble. Ntxiv mus, gliadin tshwm sim nyob rau hauv daim ntawv monomeric hauv hlwb, thaum glutenin tshwm sim nyob rau hauv daim ntawv polymeric hauv hlwb.

Cov infographic hauv qab no teev qhov sib txawv ntawm gliadin thiab glutenin hauv daim ntawv teev npe.

Summary – Gliadin vs Glutenin

Summing li, glutenin thiab gliadin yog ob hom gluten. Qhov sib txawv tseem ceeb ntawm gliadin thiab glutenin yog gliadin yog ib hom gluten uas yog dej-insoluble, whereas glutenin yog ib hom gluten uas yog dej-soluble.
