The quantification of malonaldehyde in marine lipids with para-aminobenzoic acidFollett, Mark Samuel 10 August 1967 (has links)
Malonaldehyde, a very reactive member of the homologous
series of dialdehydes, is associated with the autoxidative deterioration
of lipids. Its measurement, in autoxidized lipid systems is an
expression of the extent of oxidation, in lipids. Malonaldehyde lends
itself well to such determinations because of the sensitivity and
specificity of its quantification in complex lipid systems. Complete
knowledge of the formation of malonaldehyde in autoxidized lipids. is
lacking. Such knowledge would undoubtedly promote a better understanding
of lipid autoxidation mechanisms.
In this investigation, a method for detecting malonaldehyde
through the use of its reaction with p-aminobenzoic acid was developed.
This was adapted for use in measuring malonaldehyde in
lipids and in tissue samples. The reaction between p-aminobenzoic
acid and malonaldehyde was partially characterized, and a mechanism
for the formation of the reaction product was postulated.
The quantification of malonaldehyde in lipid systems by the use
of p-aminobenzoic acid involves the use of a mild reducing agent such
as stannous chloride to prevent interference from hyd roperoxides
present in the system. The p-aminobenzoic acid reaction is highly
specific for malonaldehyde and proceeds smoothly and rapidly at
room temperature in a non-aqueous chloroform-methanol solvent
system to yield a highly colored compound having a maximum
absorbance at 406 mμ. and with a molar absorptivity of 73,500. The
absorbance value may be converted directly to parts-per-million
malonaldehyde through the use of a conversion factor in a simple
equation. The limits of detectability of themethod are on the order
of one ppm malonaldehyde. The measurement of malonaldehyde in
the lipid fraction of tissue samples involves the prior extraction of
the lipid with a non-aqueous chloroform-methanol solvent, by an
extraction method which was developed for this purpose.
The reaction of malonaldehyde with p-aminobenzoic acid
involves the condensation of two molecules of p-aminobenzoic acid
with one molecule of malonaldehyde. The reaction exhibits a rate
maximum at a hydrogen ion concentrations of about 0.1 molar, and
also exhibits rate dependencies upon the concentrations of both
malonaldehyde and p-aminobenzoic acid. This strongly suggests that
the reaction proceeds according to an S [subscript N] 2 mechanism. A postulated
mechanism involves nucleophilic 1,4-addition of the amino nitrogen of p-aminobenzoic acid to the enol of malonaldehyde followed by-loss
of water to form the enamine. The reaction with a second molecule
of p-aminobenzoic acid involves nucleophilic substitution of the
amino nitrogen at the carbonyl function of malonaldehyde followed
by loss of water to form an imine linkage. / Graduation date: 1968

The fatty acid composition of tissues from swine fed fresh and oxidized menhaden oil containing certain antioxidantsHuang, Anita Wong 27 February 1964 (has links)
The lipid composition of swine is characteristic of the species
and is also a reflection of their dietary history. Other investigators
have established that the physical properties and composition of
swine depot fat may be altered by variation of the dietary lipid.
Dietary regimens employing vegetable oil-bearing materials and
their effect on meat quality has received the attention of animal
nutritionists for a considerable period. Less is known about the
nutritive value of the more highly unsaturated lipids, such as fish
oils, and their effect on the lipid composition of swine tissues.
Even less is known about the fate of oxidized fish oil lipids in
swine rations.
This research had for its purpose the investigation of the fate
in swine of the dietary marine lipid, menhaden oil, and its effect on
composition of depot lipids. The state of autoxidation of the oil and
the effect of certain antioxidants on the fatty acid composition of
swine was determined.
Growth studies on swine were made using menhaden oil of
various oxidation states as the dietary lipid. The effect of antioxidants,
∝-tocopherol acetate and ethoxyquin, was also investigated.
At the conclusion of the diet trials, tissue samples, representing
the five dietary regimens, were removed for analysis. The fatty
tissues examined were outer back fat, inner back fat, and kidney
fat. Samples of liver tissue for lipid analysis were also taken. The
lipids from the respective tissues were extracted and interesterified
with methanol to yield the methyl esters of the fatty acids. Hydrogenation
of the unsaturated methyl esters for chain length confirmation
was carried out.
Qualitative and quantitative gas-liquid chromatographic analysis
of the unhydrogenated and hydrogenated methyl esters of the fatty
acids were performed on diethylene glycol succinate column.
The results of these investigations showed that a particular
dietary fatty acid can be selectively deposited in animal tissues.
Long chain polyunsaturated fatty acids of menhaden oil, such as
20:5, 22:5, 22:6 were sparsely deposited in adipose tissues. The
depot fat composition showed a mixture of characteristic menhaden
oil fatty acids with the typical fat synthesized by swine.
Fatty acid composition of tissue from swine fed oxidized menhaden
oil with and without antioxidants showed very similar fatty
acid composition as those fed fresh menhaden oil. The results of
this investigation supported the beneficial effect of vitamin E
(∝-tocopherol acetate) and ethoxyquin as in vivo antioxidants. / Graduation date: 1964
