title: Natural occurrence of free fatty aldehydes in bovine cardiac muscle.
abstract: Free fatty acids, aldehydes, alcohols, and 1-O-alkyl and alk-1-enyl glycerols were identified and quantified in lipid extracts from bovine cardiac muscle. Although a number of components present in the free fatty aldehydes were also noted in the fatty chains in the 1-O-alk-1-enyl glycerols, a direct qualitative similarity did not exist as would be expected if the free fatty aldehydes were artifactual in origin. Also, a qualitative similarity did not exist between the fatty chains of the 1-O-alkyl and alk-1-enyl glycerols. This latter observation would suggest a mechanism other than biodehydrogenation of the alkyl ethers for the origin of the alk-1-enyl glycerols. Free fatty aldehydes were distributed evenly between the 105,000 g supernatant and particulate fractions of cardiac muscle, while the 1-O-alk-1-enyl glycerols were associated primarily with the particulate fraction. Free fatty alcohols were noted only in the supernatant fraction, while the 1-O-alkyl glycerols were present in both fractions.
