title: ORIGIN OF PALMITIC ACID CARBON IN PALMITATES FORMED FROM HEXADECANE-1-C-14 AND TETRADECANE-1-C-14 BY MICROCOCCUS CERIFICANS.
abstract: Finnerty, W. R. (University of Iowa, Iowa City), and R. E. Kallio. Origin of palmitic acid carbon in palmitates formed from hexadecane-1-C(14) and tetradecane-1-C(14) by Micrococcus cerificans. J. Bacteriol. 87:1261-1265. 1964.-Degradation of the palmitic acid moiety of cetyl palmitate and myristyl palmitate formed from hexadecane-1-C(14) and tetradecane-1-C(14) by Micrococcus cerificans was carried out. The patterns of C(14) labeling in palmitic acid from cetyl palmitate showed that hexadecane is oxidized at the C(1) position, and cetyl alcohol and palmitic acid thus formed are directly esterified. Palmitic acid arising from tetradecane and esterified to tetradecanol appeared to have been synthesized by the addition of two carbon atoms to an existing 14-carbon atom skeleton. Considerable mixing of C(14) occurred in the C(1) and C(2) positions of palmitic acid thus synthesized.
