1‐Pyrroline: The Odor Component of Strecker‐Degraded Proline and Ornithine

Abstract
SUMMARY: The odor component of proline and ornithine degraded by periodate, isatin, or ninhydrin was identified as 1‐pyrroline by means of gas chromatography on three columns, mass spectra, and infrared analysis. Free γ‐amino‐butanal also yields the same odor component via formation of an internal Schiff base.
