Beschreibung
Isoamyl propionate has an apricot-pineapple odor. The taste is somewhat harsh when freshly distilled but subsequently yields apleasant apricot-plum bittersweet flavor. May be prepared by esterification of propionic acid with the isomeric amyl alcohols obtained from fusel oil and other sources.

Stoffwechsel
Esters such as propionates are hydrolysed to materials that are normally in the diet or are readily converted to such materials (Fassett, 1963a). The lower toxicities of the higher propionate esters (isoamyl < n-butyl < n-propyl < ethyl) and of the higher isoamyl esters (isovalerate < n-butyrate < propionate < acetate) were attributed to their slower rates of hydrolysis, which made less free alcohol available (Selisko, Ackermann & Kupke, 1962). The metabolism of propionic acid is known to proceed by conversion to succinic acid and oxidation through the citric acid cycle(Fassett, 1963b).
