Digestão da PROTEÍNA | PROTEIN Digestion
Caminho percorrido:
1 - O pH ácido do estômago desnatura as moléculas de proteína e a enzima pepsina inicia a digestão dos aminoácidos.
2 - No duodeno, as células intestinais liberam a enteroquinase, enzima que estimula o pâncreas a liberar suas enzimas.
3 - O pâncreas libera as enzimas proteolíticas que completam a digestão de proteínas transformando-as em aminoácidos.
4 - Os aminoácidos são absorvidos pelas células intestinais.
Principais enzimas que participam na digestão de PTN:
- pepsina e renina (no estômago pelo suco gástrico);
- quimotripsina (no intestino delgado pelo suco duodenal ou entérico);
- tripsina (no intestino delgado pelo suco pancreático).

Digestion is a little more difficult, it doesn't start in the mouth like carbohydrates, but in the stomach through the gastric juice that activates the enzymes pepsin and renin, it goes to the intestine where it is received by the small intestine - duodenum where most of the digestion takes place. and all the absorption of nutrients.
Path taken:
1 - The acidic pH of the stomach denatures the protein molecules and the pepsin enzyme starts the digestion of amino acids.
2 - In the duodenum, intestinal cells release enterokinase, an enzyme that stimulates the pancreas to release its enzymes.
3 - The pancreas releases proteolytic enzymes that complete the digestion of proteins, transforming them into amino acids.
4 - Amino acids are absorbed by intestinal cells.
Main enzymes that participate in the digestion of PTN:
- pepsin and renin (in the stomach by gastric juice);
- chymotrypsin (in the small intestine by duodenal or enteric juice);
- trypsin (in the small intestine by pancreatic juice).
