Precursors of methyl ketones in butter

Butterfat, when treated with Girard-T reagent, yields a series of six pyrazolones, corresponding to six even-numbered β-ketoacids (C6 up to and including C16). This is in agreement with the formation of six odd-numbered methyl ketones (C5 up to and including C15) on subjecting butterfat to steam-deo...
