Hormoonproductie 1. A prepropeptide is synthesized and released into the rough ER. 2. Proteolytic enzymes in the RER cleave off some amino acids to yield propeptides. 3. In the smooth ER propeptides are packaged into transport vesicles. 4. The vesicles are transported to Golgi complexes. 5. Golgi complexes package the propeptide into secretory vesicles Either in the GA or secretory vesicles more amino acids are cleaved to yield the final peptide 6. The peptides are released by exocytosis Biology Notes, Cell Biology, Ap Biology, Teaching Biology, Molecular Biology, Peptide Synthesis, Endocrine System, Pearson, Physiology

A three-part diagram shows the generic chemical structure of an amino acid (top), the generic chemical structure of a polypeptide (middle), and the idealized structure of a polypeptide chain folded to form loops (bottom). A dotted line between amino acids on different loops represents their interaction.
