Žaludeční enzymy
Betaine HCL
- Http://www.fichema.cz/betaine-hcl/1291-betaine-hcl-250-g-8592861066032.html
- Betain HCl dodávající do žaludku kyselinu chlorovodíkovou, která podporuje trávení bílkovin, ničí potenciálně škodlivé mikroorganismy v potravě.
- Nejedná se o tablety ale o prášek, který je nutné dávkovat například do želatinových tobolek.
- Balení: 250 g v PET
Pepsin
- Mr 34,500
- Acidic protease
- In the stomachs of almost all vertebrates
- Zymogen, i.e., pepsinogen
- Autocatalysis in the presence of hydrochloric acid [11]
- Pepsin is an aspartyl protease
- Resembles human immunodeficiency virus type 1 (HIV-1) protease
- Responsible for the maturation of HIV-1 [11]
- Optimal activity between pH 1 and 2
- Optimal pH of the stomach is 2 to 4
- Pepsin is inactivated above pH 6.0
- Catalyzes the hydrolysis of peptide bonds between two hydrophobic amino acids [11]
Gastric pH
Blokátory protonové pumpy
- Gastric acid suppression therapy
- Hampers protein assimilation
- Relative importance of gastric protein digestion - limited
- High proteolytic activity delivered by the pancreas [5]
- Decreased pancreatic protease secretion may partly be compensated by
- Gastric
- Small intestinal compensatory mechanisms [5]
- protein malabsorption in patients with chronic pancreatitis
- Usually occurs later
- Clinically less important than lipid malabsorption [5]
- Pepsin-like protease (rennin, chymosin; EC 3.4.23.4)
- Produced as an inactive precursor, prorennin, in the stomachs of all nursing mammals [11]
- Converted to active rennin (Mr 30,700) by
- The action of pepsin
- By its autocatalysis
- Extensively in the dairy industry to produce a stable curd with good flavor
- Specificity in cleaving a single peptide bond in ?-casein
- Generate insoluble para-?-casein and C-terminal glycopeptide [11]
