Protein alpha helix — FTIR absorption peaks and assignments
These are the characteristic FTIR wavenumbers where Protein alpha helix tends to absorb, compiled from published literature and ranked by supporting evidence. Each assignment is traceable to a source (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.
