Study Notes
Protein Digestion
- Trypsin targets neutral nonpolar amino acids during protein digestion.
- Chymotrypsin targets aromatic amino acids during protein digestion.
- Carboxypeptidase targets basic amino acids during protein digestion.
- Peptidases break down dipeptides and tripeptides during protein digestion.
Protein Absorption
- The PepT1 transporter is responsible for the absorption of dipeptides and tripeptides.
- Proline, hydroxyproline, and glycine have the slowest transporter affinity during protein absorption.
- Basic and neutral amino acids have the quickest transporter affinity during protein absorption.
Protein Catabolism
- Deamination is the process of removing the amino group from an amino acid.
- The end product of deamination is ammonia.
- The main purpose of protein catabolism is to produce energy.
- The liver is responsible for ammonia excretion during urea synthesis.
- Transamination involves the transfer of the amino group from one amino acid to another.
- The end product of transamination is a different amino acid, often an α-keto acid.
