This is module 11 of the NeoPeptidos Professional Certification in Peptide Science. It has 3 lessons; each one can be read on its own and all of them are part of the syllabus assessed at the end of the module.
Lesson 1. Chemical degradation: the weak points of the sequence
A peptide does not «go bad» at random: it degrades through specific chemical reactions that occur at specific residues. Knowing them makes it possible to predict which peptides are fragile and why they are stored the way they are.
Read the lesson →Lesson 2. Physical degradation: aggregation and adsorption
A peptide can lose activity without any covalent bond breaking: it is enough for its physical state to change.
Read the lesson →Lesson 3. Lyophilization and excipients
Lyophilization is the reason a peptide can travel at room temperature and keep for years. Understanding the process explains what a vial actually contains.
