Li, Solid-Liquid-Gas Equilibrium of the Ternaries Ibuprofen + Myristic Acid + CO 2 and Ibuprofen + Tripalmitin
+ CO2, J.
coremiiforme V3 producing two types of LipA and LipB lipases exhibited an elevated activity with p-nitrophenyl laurate and LCFA glycerides such as trioleate (C18:1) tripalmitin
(C16:0) where hydrolysis of ester bonds occurred at 1,3-positions .
Glyceryl tripalmitate (tripalmitin
) (Sigma-Aldrich, Milan, Italy) was used as a standard for lipid extraction (Holland, Gabbott 1971).
Increasing the percentage of vegetable oil in the butter gradually increased the difference between the relative areas of the peaks and specifically decreased the ratio of peak 3 (corresponding to tripalmitin
) and peak 4 (corresponding to triolein), depending on the degree of adulteration.
Lipids like glyceryl tripalmitate (tripalmitin
), glyceryl monostearate, glyceryl tristearate, and surfactants--poloxamers (Pluronic F68 and Pluronic F127)-were purchased from Sigma Aldrich.
The lipid classes and respective standards were phospholipid (PL; 1-[alpha]-phosphatidylcholine), free sterol (ST; cholesterol), free fatty acid (FFA; palmitic acid), acetone-mobile phospholipid (AMPL; 1-monopalmitoylglycerol), TAG (tripalmitin
), diacylglycerol (DAG; 1, 2-Dipalmitoyl-rac-glycerol (C16:0)), ketone (KET; 3-Hexadecanone), aliphatic hydrocarbon (AH; Nonadecane), wax ester (WE; lauric acid myristyl ester), methyl ester (ME; methyl palmitate), and fatty alcohol (FALC; 1-hexadecanol).
Later, among various lipids and non-lipids tested, it was found that in addition to the above two phospholipids, cardiolipin was the most effective activating lipids, and tripalmitin
and tristearin were less effective.
Effects on phase transitions in tripalmitin
due to the presence of dipalmitin, sorbitan-monopalmitate or sorbitan-tripalmitate.
 on nanoparticles produced by tripalmitin
could be mentioned.
