Study Notes
Amino Acid Structure
- Amino acids consist of a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain (R group)
Protein Composition
- The specific protein composition is determined by the sequence of amino acids, which is encoded by the genetic code
Digestion of Peptides and Amino Acids
- Digestion of peptides and amino acids starts in the stomach, where gastric enzymes such as pepsin break down proteins into smaller peptides and amino acids
Regulation of Digestion
- The digestion process is regulated by hormones, such as gastrin, secretin, and cholecystokinin, which stimulate the release of digestive enzymes
Absorption and Transport
- Absorbed peptides and amino acids travel to the liver via the hepatic portal vein after digestion
- The liver then distributes them to the rest of the body for protein synthesis and other cellular functions
