This is module 1 of the NeoPeptidos Professional Certification in Peptide Science. It has 4 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. From amino acid to peptide
A peptide is a polymer of amino acids joined by peptide bonds. It shares its raw material with proteins; the difference is length and, with it, functional specificity.
Read the lesson →Lesson 2. Levels of structure and structure-activity relationship
Biological activity emerges from conformation, which is described in hierarchical levels:
Read the lesson →Lesson 3. Classification and solid-phase synthesis
Peptides are classified by several simultaneous criteria:
Read the lesson →Lesson 4. Chemical modifications: from the natural sequence to the analog
Almost no peptide of pharmacological interest is an untouched natural sequence. Between the endogenous peptide and the analog being studied there is a set of chemical modifications with a specific purpose: resisting enzymes, locking in the active conformation or changing the pharmacokinetics.
