Thus, despite the fact that Lpcat3 can catalyze the esterification of multiple unsaturated acyl chains into PC in vitro, and despite the fact that Lpcat3 is by far the most abundant Lpcat family member in the liver, the consequences of loss of Lpcat3 for PL composition were remarkably selective.
Binding could be favored by the presence of multiple cis double bonds in the fatty acyl chain because potential energy wells for rotation about C C bonds adjacent to a double bond are low.
A variety of ceramide species with acyl chain lengths of C16 C24 and multiple counterions (H+, Na+, or K+) were detected primarily in the homozygous Asah1P361R/P361R kidneys, relative to heterozygote and control kidneys, and varied in chain length for each species by 28 mass units.
In addition, AHL signal production is a consequence of sloppy active site selection for the acyl chain and hence a single synthase will often make multiple AHL types.
Other bacteria incorporate a cyclopropane ring near the centre of the acyl chain.
Therefore, we tested six acyl-CoA species of different acyl chain lengths.
Comparison of surfactin congeners differing by geometry, charge and acyl chain length indicated a strong dependence on acyl chain length.
For example, the acyl chain specification 16:0 corresponds to hexadecanoyl, and 20 4 7E,10E,13E,16E) implies 7E,10E,13E,16E-eicosatetraenoyl.
The mass fragmentation per lipid class is highly conserved among their acyl chain varieties.
The acyl chain lengths of fatty acid and sphingoid moieties ranged 12 36 and 14 30, respectively.
