Ammonium linoleate

Figure 10 is a ternary diagram for the systems Triolein/S/ Methanol, where S is respectively 4/1 molar ratios of 2-octanol to bis(2-ethylhexyl) sodium sulfosuccinate, triethylammonium linoleate or tetradecyldimethyl ammonium linoleate at 25°C. Not much difference is noted between phase areas for the triethylammonium linoleate and bis(2-ethylhexyl) sodium sulfosuccinate systems. Both are definitely inferior to the tetradecyldimethylammonium linoleate which shows the greatest solubilized area of methanol in triolein at 25°C.

An HPLC chromatograph was used together with a mass detector (when required, a stream splitter (app. 10 1) was inserted between the column and the detector). A column (250 X 4.6-mm ID) of NUCLEOSIL 5SA was flushed with 1% aqueous ammonium nitrate solution at a flow rate of 0.5 ml/min for 1 h, then with distilled water at 1 ml/min for 1 h. Silver nitrate (0.2 g) in water (1 ml) was injected onto the column in 50-/zl aliquots at 1-min intervals silver began to elute from the column after about 10 min. Twenty minutes after the last injection, the column was washed with methanol for 1 h, then with 1,2-dichloroethane-dichloromethane (1 1) for another hour. The three solvent reservoirs contained the following (A) 1,2-dichloroethane-dichloromethane (1 1) (B) acetone and (C) acetone-acetonitrile (9 1). For linoleic acid-rich seed oils, gradients of A were employed to 50% A-50% B over 15 min, then to 50% B-50% C over a further 25 min and held there for 5 min. For linolenic acid-rich seed oils, C was changed to acetone-acetonitrile (4 1), and the flow rate was increased to 1 ml/min gradients of A were utilized to 50% A-50% B over 10 min, then to 70% B-30% C over 20 more min, and finally to 100% C over another 30 min. 

Phosphatidylcholines, or lecithins, are zwitterionic over a wide pH range because of the presence of a quaternary ammonium group and a phosphate moiety. Phosphatidylcholines are the most abundant phospholipids in animal tissues and typically contain palmitic, stearic, oleic, linoleic, or arachidonic acid, usually with saturated fatty acids in the sn- position and unsaturated fatty acids at sn-2.

The antioxidant activity of phenols used and standards was determined according to die ferric thiocyanate method with minor modifications. Each sample of treated wool (200 mg) was mixed with 2 mL distiUed water and 5 mL linoleic acid emulsion (0.02 M, pH 7.0) and 5 mL phosphate bufier (0.2 M, pH 7.0). Linoleic acid emulsion was prepared by mixing 0.5608 g of linoleic acid with 0.5608 g of Tween 20 as emulsifier, and 100 mL phosphate buffer (0.2 M, pH 7.0), and then the mixture was homogenised. The reaction mixture was incubated at 37 C. Aliquots of 0.1 mL wm taken at different intervals during incubation. The degree of oxidation was measured by sequentiaUy adding 4.7 mL ethanol (75%), 0.1 mL ammonium diiocyanate (30 %), 0.1 mL sample solution and 0.1 mL ferrous chloride (0.02 mg, in 3.5% HCl). The mixture was... 

Ammonium soaps n. Soaps formed by reaction of ammonia with the higher molecular weight fatty acids, such as ammonium ole-ate, linoleate, stearate, etc., used as wetting or emulsifying agents. 

A major problem in LOX assays is adequate dispersion of the fatty acid substrates. Although the usual substrate, linoleic or linolenic acid, forms soluble soaps at pH 9 (optimal for the soybean type-1 enzyme), most LOXs require a pH between 5.5 and 7.0, and in this range fatty acid dispersions are unstable. Ammonium or K" " salts, with or without added emulsifiers (Tween-20, Triton X-100, etc.) are normally used. However, reproducibility of substrate preparations is difficult to achieve, and some variation in apparent substrate concentration may be experienced. In the authors laboratories 5 X 10 M linoleic acid and Triton X-100 (250 /xg/ml) have normally been used in the assay medium. Oxygen consumption (in moles per/minute) is calculated from initial rates, assuming a dissolved oxygen concentration of 240 fiM at 25°C in air-saturated solutions. 

Production of singlet oxygen (both Eg and Ag) by selfreaction of s-butylperoxy radicals and the peroxy radicals derived from linoleic acid has very recently been confirmed by analysis of the emission spectra observed during ceric ammonium nitrate oxidation of the. appropriate hydroperoxide ( 8).
