Cov enzyme salivary amylase yog nquag nquag pH ntawm 6.8. Peb lub plab muaj qib siab ntawm acidity uas ua rau salivary amylase rau denature thiab hloov nws cov duab. Yog li cov salivary amylase tsis ua haujlwm thaum nws nkag mus rau hauv plab.
Kuj paub, qhov twg yog salivary amylase nquag?
Amylase tau pom nyob hauv ob qhov chaw tseem ceeb - qaub ncaug hauv qhov ncauj thiab kua txiv pancreatic nyob rau hauv pancreas . Pancreatic kua txiv yog secreted rau hauv cov hnyuv qhov twg nws pab ntxiv digestion. Hauv ob cheeb tsam amylase pab txhawm rau zom cov hmoov txhuv nplej siab rau hauv cov piam thaj yooj yim.
Tom qab ntawd, lo lus nug yog, yuav ua li cas tshwm sim rau kev ua ntawm salivary amylase hauv plab? Salivary amylase pib tawg cov hmoov txhuv nplej siab hauv lub qhov ncauj thiab txuas ntxiv mus ua yog li tom qab cov zaub mov dhau mus rau hauv plab thiab cov hnyuv me. Salivary amylase ua haujlwm zoo tshaj plaws ntawm qhov nruab nrab pH, tab sis tuaj yeem muaj sia nyob plab kua qaub.
Thiab cov lus nug yog, dab tsi ua rau salivary amylase?
Anionic ua kom ntawm tib neeg salivary amylase . Daim ntawv tshaj tawm tam sim no qhia pom cov txiaj ntsig ntawm cov ions sib txawv ntawm tus kheej nrog Tris thiab amino acid. Txawm hais tias nws tau lees paub tsis ntev los no tias sodium ion yog tus ua haujlwm ntawm alpha- amylase , txoj kev tshawb fawb no lees paub tias sodium ion tsis ua qhib neeg salivary amylase.
Puas muaj amylase nyob rau hauv cov qaub ncaug?
Tib neeg qaub ncaug alpha amylase (HSAmy) yog ib qho tseem ceeb enzyme pom nyob rau hauv lub qhov ncauj kab noj hniav. Nws belongs rau glycoside hydrolase tsev neeg thiab muaj nyob rau hauv ntau yam isoforms nyob rau hauv qaub ncaug zais zis. Tib neeg tsim ob hom alpha amylase ( qaub ncaug thiab pancreatic amylase ) uas tag nrho qhia txog 97% homology.
