The alkanes generated from stearoyl-ACP and palmitoyl-ACP. Concept introduction: All cyanobacterial membranes contain alkanes at a concentration similar to that of the chlorophyll. The alkanes are produced from the fatty acids in three steps. The first step is the activation of the fatty acid by an acyl-carrier-protein followed by the reduction of the activated fatty acid to an aldehyde and the final step is the decarbonylation of the aldehyde. These steps result in an alkane that is one carbon short of the original fatty acids.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
