Protein digestion occurs mainly in the stomach and also in the small intestine.
When protein food is eaten and enters the stomach, the hydrochloric acid in the stomach "denatures" the protein. This means it starts to break the protein down into short chains of amino acids joined together (peptide chains).
This is also when the the hydrochloric acid (HCl) also activates an enzyme called pepsin to participate in the break-down of the protein.
After this, the broken down protein enters into the small intestine where it is further broken down into the di-peptides (2 amino acids joined together) by pancreatic enzymes and then into its individual amino acids by other pancreatic enzymes.
The amino acids are absorbed through the small intestine and travel in the blood stream into the liver.
proteins are the only food molecule that are digested in the stomach
Proteins are broken down into amino acids, and most of this happens in the stomach and small intestines...
man i need a life...
In the stomache it secretes an acid and something named Pepsin
the mouth, stomach and small intestine
oxidation
Protein is digested by resting
Protein is digested to form amino acids. Lipids are digested to fatty acids. Carbohydrates are digested to glucose and other simple sugars.
Protein is digested in the stomach and small intestine.
Protein is digested by resting
Protein is digested both in the stomach (by pepsin and trypsin) and in the small intestine.
Amino acids
The body breaks digested proteins into amino acids
Protein
amylases
When you chew, you activate the salivary glands which breakdown protein in the food.
Amino Acids
Carbohydrates are more easily digested than protein.
