Protein Digestion
Definition
Protein digestion is the process by which the body breaks down dietary proteins into amino acids that can be absorbed and used for various bodily functions.
Scientific / Technical Definition
Protein digestion begins in the stomach, where the acidic environment and enzyme pepsin initiate the breakdown of protein molecules into smaller peptides. As the food bolus enters the small intestine, further enzymes such as trypsin, chymotrypsin, and carboxypeptidase from the pancreas continue the process, ultimately resulting in the release of amino acids which are absorbed through the intestinal wall into the bloodstream.
Benefits
- Facilitates the growth and repair of tissues
- Supports immune function
- Provides body with essential amino acids
- Contributes to enzyme and hormone production
Examples
- Lean meats like chicken and turkey
- Fish and seafood
- Eggs
- Dairy products like milk, cheese, and yogurt
- Beans and legumes
Additional Information
- Importance: Protein digestion is crucial for making amino acids available for various physiological processes, including muscle building, repair of tissues, and synthesis of enzymes and hormones.
