Detailed Explanation
The complete set of all peptides present in a specific cell, tissue, organ, or organism at a given time under defined conditions. Peptidomics — the systematic study of the peptidome — uses mass spectrometry-based approaches to identify and quantify peptides, much as proteomics studies the complete protein complement.
Unlike proteomics, peptidomics focuses specifically on molecules under ~10 kDa and often requires specialized sample preparation to prevent post-mortem degradation. Peptidomics has revealed thousands of previously unknown bioactive peptides in brain tissue, blood, and other biological fluids, and is increasingly used in biomarker discovery for diseases like cancer, neurodegeneration, and cardiovascular disease.
