A rapid and simple method for the determination of esterified fatty acids and for total fatty acids in blood.
Carboxylic acid esters react with hydroxylamine in alkaline solution to form hydroxamic acids. These acids produce a red to violet reaction with ferric chloride which has been utilized by Feigl (1949) for the microchemical detection of carboxylic acid derivatives. Lipmann and Tuttle (1945) developed a method for the quantitative assay of acylphosphates by allowing hydroxylamine to react with th...
متن کاملA method for analysis of fatty acids in coral
A method using gas-liquid chromatography was developed to analyze the total fatty acid composition of animals having carbonate skeletons and used to determine the fatty acids in a scleractinian coral and a milleporine coral. The major acid in both samples is palmitic acid, and marine-type polyunsaturated fatty acids were not detectable in either type of coral. We have developed a method to meas...
متن کاملFast and Simple Free Fatty Acids Analysis Using UPC2/MS
The common fatty acids of animal and plant origin have even-numbered chains of 16 to 24 carbon atoms with 0 to 6 double bonds. Nature provides countless exceptions, however, and oddand even-numbered fatty acids with up to nearly 100 carbon atoms exist. In addition, double bonds can be of the cis (Z) and trans (E) configuration and there can be innumerable other structural features, including br...
متن کاملUltrasound Assisted Emulsification Microextraction as a Simple Preconcentration Method for Determination of Atrazine in Environmental Samples
We represent an environmentally friendly sample of pre-treatment method, ultrasound assisted emulsification microextraction (USAEME) followed by gas chromatography nitrogen phosphorous detector (GC-NPD), to specify atrazine residues in environmental samples. Some parameters affecting the extraction efficiency such as the type and volume of the extraction solvent, emulsification time and additio...
متن کاملStudying the amount of fatty acids and aflatoxin in traditional sweet samples of Yazd in 2018
Background & Aim: The consumption of food materials containing aflatoxin and saturated and trans fats can cause the occurrence of disease in human. The present study was done to evaluate the frequency of B1, B2, G1 and G2 aflatoxins and fatty acids in traditional sweet samples of Yazd city. Methods: 108 sweet samples including Louz, Baghlava and Ghotab were purchased from the shopping centers ...
