title: [Manifold reflection infrared spectroscopy of the hair of mice with an experimental amino acid metabolism disease (L-acetidin-2-carboxylic acid incorporation instead of proline). A model for the use of infrared spectroscopy as a screening method for metabolic diseases].
abstract: 8 mice were given L-acetidin-2-carboxylic acid orally over a period of 5 weeks. Another 8 mice served as control animals. Finally, the mice were sacrificed, their hair samples were hydrolized and applied to thin layer chromatography which revealed the incorporation of L-acetidin-2-carboxylic acid into mouse hair expressed by an additional spot. This experimental amino acid metabolic disorder served as a model for the application of infrared spectroscopy for screening hair in order to check metabolic disorders. As the multiinternal reflection-infrared spectra showed significant differences we suggest that infrared spectroscopy can be used as a noninvasive screening technique.
