Study Notes
Amino Acid Metabolism
- Ornithine plays a crucial role in amino acid metabolism, particularly in the urea cycle.
Peptide Antibiotics
- Gramicidin is an example of a peptide antibiotic produced by Bacillus brevis.
Post-Translational Modification of Proteins
- Hydrolysis is not a post-translational modification of proteins.
Signaling Molecules
- Amino acids, such as tyrosine and tryptophan, serve as precursors to some signaling molecules.
Organ Roles in Amino Acid Metabolism
- Various organs, including the liver, kidneys, and brain, play distinct roles in amino acid metabolism, such as synthesis, degradation, and regulation.
