highly likely that, for example, 34-carbon acyl chain groups represent phospholipids with mismatched side chains, while 36-carbon acyl chain groups represent phospholipids with two 18-carbon (matched) side chains.
For lipase catalysed transesterification of (Z)-3-hexene-1-ol with vinyl acetate under conditions of irreversible acyl transfer produces a chromatogram of product mixtures along with their retention times is shown in Fig.
VERO cell cytotoxicity assay was also done for the most active compound (6) bearing C6 acyl chain which showed CC50 10.216 ug/mL and selective index (SI), defined as VERO CC50/IC90, 3.394.
The acylated chitosans (LChA) were labeled based on the acyl chain length and mole ratio, for example, LChC4-M.8 was chitosan acylated with butyryl group at a mole ratio of 1:0.8.
Second, the grafting process is carried out via an amidation reaction occurred between the amine and acyl chloride groups formed on GO and carbon fibers, respectively.
Finally, the acyl chain binds in a hydrophobic channel formed by the C-terminal domain insertion with the chain terminus extending into solvent, suggesting that, while presence of the chain is critical for activity, LpxC has little specificity for chain length (Figure 4) [31, 35, 36].
Peaks at 2922 [cm.sup.-1] and 2852 [cm.sup.-1] are attributable to aliphatic stretching vibrations of the acyl side chain in triacylglycerols [30].
Recently, we have studied the liquid phase of hydrated DMPC and POPC bilayers [25] by means of quasi-elastic incoherent neutron scattering measurements and have identified three dominant dynamical processes on the ns-ps time scale, ascribed to three different motions of phospholipid molecules: (i) a fast uniaxial rotational diffusion, (ii) conformational, jump-like dynamics of the acyl chain along with threefold rotation of methyl groups, and (iii) overall diffusion dynamics confined within the first-neighbours cages.
Figure 5 showed the changes in the conversion with time for the direct esterification and transesterification in tert-butanol at 50[degrees]C with molar ratio of acyl donor to ascorbic acid of 5 : 1.
