Article Synopsis
- Nitration of tyrosine is a modification that occurs in proteins and peptides during oxidative stress, affecting various diseases but is challenging to monitor.*
-
- The study uses electron-vibration-vibration (EVV) two-dimensional infrared (2DIR) spectroscopy to analyze tyrosine nitration in peptides, successfully distinguishing different states of 3-nitrotyrosine.*
-
- Results show that EVV 2DIR spectroscopy can detect nitration levels as low as 1% in peptides, and a proposed resonant Raman probe could enhance sensitivity for even lower levels.*
