How can you identify keratin from FTIR?
This page summarizes the recurring FTIR evidence reported for keratin, including the most frequent peaks, supporting functional groups, and literature-backed interpretation patterns. It is a structured evidence page, not a claim of automatic single-spectrum certainty.

Respuesta rápida
keratin is usually reported with a recurring pattern of peaks and functional-group evidence. The most useful approach is to cross-check at least two characteristic peaks before treating it as a match, then verify whether the full spectrum still fits the same material family.
Interpretación de picos
Materiales / grupos posibles
| Grupo funcional | Evidencia |
|---|---|
| Amide | 21 |
| Protein alpha helix | 8 |
| Hydroxyl (O-H) | 6 |
| N h | 5 |
| Carbonyl (C=O) | 4 |
| Methacrylate | 3 |
| Ester | 3 |
| Acetate | 3 |
Lógica de espectro
The logic here is evidence aggregation: repeated literature mentions of keratin, repeated peak positions, and repeated functional-group associations. A strong material hypothesis should still be supported by multiple peaks that agree with each other, not by one headline band alone.

Errores comunes
- Llamar a una coincidencia de material demasiado pronto porque está presente un pico famoso.
- Ignorando la preparación de la muestra, cargas, oxidación, agua o aditivos que pueden cambiar el patrón aparente.
- Usando evidencia de la literatura sin verificar si su propio modo de muestreo y calidad del espectro son comparables.
Consejo de verificación
Use DSC, GC-MS o TGA para validar la hipótesis del material cuando el patrón de picos sea ambiguo o mixto.
