Zogulitsa

1. Makhalidwe: White kapena chikasu pang'ono, crystalline kapena amorphous ufa.

2. M'zigawo Source: Porcine chapamimba mucosa.

3. Njira: Pepsin imasiyanitsidwa ndi mucosa ya m'mimba ya nkhumba pogwiritsa ntchito njira yapadera yochotsera.

4. Zizindikiro ndi ntchito: Amagwiritsidwa ntchito kwambiri chifukwa cha dyspepsia yomwe imayamba chifukwa chomwa zakudya zama protein, kuchepa kwa m'mimba mu nthawi yochira komanso kusowa kwa proteinase ya m'mimba chifukwa cha matenda a atrophic gastritis, khansa ya m'mimba komanso kuchepa kwa magazi m'thupi.Pepsin ndi puloteni yomwe imatulutsidwa m'chimbudzi cha nyama zoyamwitsa.Zimagwira ntchito yophwanya mapuloteni kukhala ma peptide ang'onoang'ono omwe amatha kuyamwa mosavuta ndi matumbo aang'ono.

5. Zochita za Biochem / physiol: Mosiyana ndi ma peptidase ena ambiri, pepsin hydrolyzes ma peptide okha, osati amide kapena ester linkages.Maonekedwe a cleavage amaphatikizapo ma peptides okhala ndi asidi onunkhira kumbali zonse za peptide chomangira, makamaka ngati zotsalirazo zilinso zonunkhira kapena dicarboxylic amino acid.Kuchuluka kwa chiwopsezo cha hydrolysis kumachitika ngati pali amino acid wokhala ndi sulfure pafupi ndi chomangira cha peptide, chomwe chili ndi amino acid onunkhira.Pepsin adzatsikanso kumbali ya carboxyl ya phenylalanine ndi leucine, komanso pang'ono mbali ya carboxyl ya zotsalira za glutamic acid.Simalumikizana ndi valine, alanine, kapena glycine.ZL-tyrosyl-L-phenylalanine, ZL-glutamyl-L-tyrosine, kapena ZL-methionyl-L-tyrosine angagwiritsidwe ntchito ngati magawo a pepsin digestion.Pepsin amaletsedwa ndi ma peptide angapo okhala ndi phenylalanine.
