Jamaican scientists added acetic anhydride to starch in order to substitute the hydrogen of a hydroxyl group on the starch molecule with an acyl group. This was done by controlling the pH at 8.0 to 8.3 with the periodic addition of 0.1M of sodium hydroxide.
The most abundant plasma LPA species are 18:2 > 18:1 [greater than or equal to] 18:0 [greater than or equal to] 16:0 [greater than or equal to] 20:4 with an acyl group [11, 12].
Indeed, enhanced LCAT activity (1.2-fold), its cofactor-activator apo A-I (2-fold) and its reaction product [HDL.sub.2]-CE (2.1-fold) were observed, whereas [HDL.sub.3]-PL (enzyme substrate) and [HDL.sub.3]-UC (acyl group acceptor) were 1.2- and 2.4-fold lower.
The following steps might occur sequentially in the hydrolysis of PC: (1) Binding of PC to Site I; (2) Transfer of the acyl group at sn-2 to the catalytic site and simultaneous binding of the resultant lysoPC to Site II; (3) Transfer of sn-2 acyl group to H2O; (4) Transfer of sn-1 acyl group to the catalytic site; (5) Transfer of sn-1 acyl group to H2O.

In addition to its essential role in permitting mitochondrial import and oxidation of long chain fatty acids, carnitine also functions as an acyl group acceptor that facilitates mitochondrial export of excess carbons in the form of acylcarnitines.
