Nonphosphatide aldehydogenic lipids in milk fat, beef tallow, and ox heart

Gas Chromatographic and Mass Spectral Identification of Some Volatile Components of Gamma-Irradiated Milk Fat

“…Tangier and Day (18) have suggested that methyl ketones are formed in heated milk fat as a result of hydrolysis. Also, long chain aldehydes occur in milk fat as bound aldehydes (9,24). Thus, irradiation-induced hydrolysis of ester and enol-ether linkages is probably a likely mechanism accounting for the production of ketones and long chain aldehydes in irradiated milk fat.…”

Intermediate steps in the incorporation of fatty acids into long-chain, nonisoprenoid hydrocarbons by lysates of Sarcina lutea

“…The precipitate was washed with water and acetone and the free aldehydes were regenerated by shaking with 0.5 n HC1 and again converted into the 2,4-dinitrophenylhydrazones. These had a Xmax at 258 µ; and using e2i8 22,500 (Schogt et al, 1960), the yield of aldehydes was 0.63 µ ß from 3 g dry weight of cells. This would be a minimum figure for cell content of fatty aldehydes since losses in the preparation were inevitable.…”
