Glycerol trioleate

The reaction of condensed phosphoric acid with castor oil gave a poly-phosphoric acid ester, which after neutralization with ammonia shows a high wetting power [32]. Glycerol trioleate was reacted with octametaphosphoric acid at 40°C in the presence of acetic acid anhydride. The reaction product was neutralized with triethanolamine [32,33]. 

C] and 6% Cj g) was used as the anionic surfactant. Oleic Acid (Extra pure reagent, Kanto Chemical Co., Tokyo, Japan), Triolein (glycerol trioleate (Cj 2H33C00)3C3H5, Technical, BDH Chemicals, England) and n-decane (E. Merck, G.C., 95%) were used as oil. Sodium chloride (E. Merck, purity 100 0.05%) was used as electrolyte. 

Oleic acid may be obtained from glycerol trioleate, present in many liquid vegetable and animal nondrying oils, such as olive, cottonseed, lard, by hydrolysis. The crude oleic acid after separation of the water solution of glycerol is cooled to fractionally crystallize the stearic and palmitic acids, which are then separated by filtration, and fractional distillation under diminished pressure. Oleic acid reacts with lead oxide to form lead oleate, which is soluble in ether, whereas lead stearate or palmitaie is insoluble, prom lead oleate oleic add may be obtained by treatment with IL 5 (lead sulfide, insoluble solid, formed). With sodium oleate, a soap is formed. Most soaps are mixtures of sodium stearate, palmitate. and oleate.

After the diagnosis of X-ALD was established, the patient was placed on a regimen of 45 cc daily (qd) of Lorenzo s oil, 30 cc qd glycerol trioleate oil, and dietary restriction of VLCFA, which resulted in normalization of the plasma VLCFA. His family had decided to pursue bone...

My district hospital laboratory, serving a population of about 500,000, offers fecal microscopy and the C-glycerol trioleate ( C-triolein) fat absorption test. ... 

As for as the monoester selectivity is concerned. Figure 2 shows that the formation of monoester decreases with increasing conversion, which is what can be expected from a kinetic point of view. At the same time, the formation of diester increases but the selectivity to glycerol trioleate is still very low. 

Glycerol trioleate has been used in an attempt to simulate lipid membranes and to take into account some of the solvent associations plausibly occurring in biota an impressive direct correlation was observed between log Phv (Phv is the partition coefficient between glycerol trioleate and water) and BCF values in rainbow trout expressed on a lipid basis, and these results were used to support the view that the bioconcentration of nonpolar hydrophobic xenobiotics is significantly determined by their lipid solubility (Chiou 1985). This conclusion is further supported by the results of an extensive examination of a series of highly hydrophobic compounds which do not demonstrate a high potential for bioconcentration (Chessells et al. 1992). 

A lipase has been used to convert solid triolein (glycerol trioleate) to the monooleate by treatment with glycerol at 8°C.75 Other lipases have been used in the hydrolysis and transesterification of oils, as well as in the esterification of fatty acids without solvents.76 Peptides can be produced from eutectic mixtures of amino acid derivatives with the addition of a small amount of solvent.77 Immobilized sub-tilisin and thermolysin were used with 19-24% water or an alcohol to produce polypeptides. Subtilisin on celite (a di-atomaceous earth) was used to convert a mixture of L-phenylalanine ethyl ester and L-leucinamide containing 10% triethyleneglycol dimethyl ether to L-phenylala-nineleucinamide in 83% yield. Addition of 30% 2 1 ethanol/water reduced the time needed from 40 to 4 h. The enzyme could be used three more times. These reaction mixtures contained 0.13-0.75 g peptide per g reaction mixture compared with 0.015-0.035 when the reaction was...
