Post-translational modifications (PTMs) are biochemical changes that occur during or after protein synthesis and regulate protein structure, activity, stability, localization, interactions, and degradation. This overview introduces the major types of PTMs, their biological functions, mechanisms, role in disease, and methods used to study protein modifications.

Peptides are short chains of amino acids that act as essential messengers, regulators, and structural molecules in living organisms. This article explores how peptides are formed, how they function, and why they are vital in biology and modern medicine.
