The physical properties, such as melting points, specific heat, viscosity, density, and refractive index depend on the type of fatty acids present in the triglyceride and their location, chain length of fatty acids, number and location of cis and trans double bonds on the fatty acid chains as well as compatibility of the different triglycerides in the mixture and the type of crystal present. 

The Codex Alimentarius standard includes limits for acidity, volatile matter, insoluble impurities, peroxide value, colour, odour, taste, iron, copper, K27o, AK, permitted additives, contaminants (lead, arsenic, halogenated solvents), refractive index, saponification value, iodine value and unsaponifiable matter. Physical and chemical constants, such as iodine value and saponification value, are not found in the EU regulation. This is explained by the fact that more definite information is obtained by determining fatty acid composition, sterol and wax composition, trans fatty acid content, stigmastadiene, and so on. 

Hundreds of retinoids have been synthesized over a period spanning almost 15 years. Several firms, research institutes, and academic institutions have dedicated efforts to synthesize retinoids with an improved therapeutic index (ratio of potency to toxicity) relative to the standards, all-trans-retinoic acid (1) and 13 -ciy-retinoic acid. The strategies have varied significantly. Two tendencies are observed (a) to synthesize retinoids with improved anti-cancer activity relative to RA with the expectancy of minimal difference in toxicity relative to RA, and (b) to synthesize retinoids with improved toxicity profiles relative to RA with the expectancy of altered but not diminished anti-cancer activity relative to RA.

Analytical chain to monitor vegetable oil hydrogenation , in which the progress of the hydrogenation reaction is followed by on-line trans-ds A measurement by infra-red attenuated total reflectance and off-line measurements of refractive index and fatty acid composition by gas chromatography (1982). 

It is even possible to estimate that a mixture consists of a% fat A, b% fat B, etc. on the basis of the fatty acid composition according to method 6.2.16. Usually it is also in this case necessary to include other constants such as refractive index and trans content... 

Composition of oil/fat. To study the composition of oil/fat it is essential to test the purity of an oil/ fat for adulteration, accidentally or voluntarily. The specific fatty acid in fat can be determined by GC by preparing methyl esters with sodium methoxide. Mass spectrometry coupled to GC (GC-MS) is the most powerful tool for identification of fatty acids separated by GC. Free fatty acids in oil (index of rancidity) can be determined by titration against standard alkali. Infrared (IR) spectroscopy, Raman spectroscopy, and ultraviolet (UV) spectroscopy (200—400 nm) are used to detect isomers (trans and cis) of unsaturated fatty acids and conjugated double bonds. It is important to study saponification value (depict fatty acid chain length), iodine value (give the degree of unsaturation), and hydroxyl value (free fatty acids present in fats).

Monodispersed (polydispersity index = 1,04) polystyrene and polyisoprene with a molecular weight in the range of 2 x 10 were used as the carrier polymers by Bates and Baker [18,51]. The isoprene polymer was synthesized anionically at -78°C using toluene as the solvent. It was composed of approximately 80% cis 1,4, 15% trans-, A and 15% 3,4-disubstitutedrepeating units. A few percent (3%) of butadiene were randomly copolymerized with styrene anionically at 25°C in order to provide unsaturated moieties for the next modification step. Electrophilic sites were then introduced into the respective carrier polymers by either oxidation or epoxidation. It was expected that the sites consist mainly of aldehydes, ketones, and/or epoxides. ffj-Chloroperbenzoic acid (m-CPBA) was found to be effective in epoxidation of the unsaturated moieties in...
