Identifying and Measuring Endogenous Peptides through Peptidomics

Area of Science:

• Biochemistry
• Proteomics
• Physiology

Background:

• Endogenous peptides, including neuropeptides and peptide hormones, are crucial for intercellular communication and physiological regulation.
• These peptides hold potential as biomarkers for various health conditions.
• Current methods for studying endogenous peptides are often targeted, limiting comprehensive analysis.

Purpose of the Study:

• To introduce the field of peptidomics to researchers.
• To highlight mass spectrometry-based peptidomics as a powerful, relatively nontargeted approach.
• To encourage the application of peptidomics for endogenous peptide research.

Main Methods:

• Mass spectrometry-based peptidomics.
