Combined standard(SPPE) and inverse(IPPE) photopyroelectric configurations for measurement of dynamic thermal parameters of saturated and unsaturated fatty acids
نویسندگان
چکیده
Combined SPPE-IPPE method is proposed to obtain thermal parameters (thermal effusivity, diffusivity, conductivity and volume specific heat) of saturated (caproic C1O:O) and monoenoic unsaturated (oleic C18: 1, cis) fatty acids. The method was also used to investigate temperature behaviour of thermal parameters (around the melting point) for lauric acid (C12:O). The combined SPPE-IPPE approach eliminates problems associated with sample's transparency and thickness control.

Background: Cardiovascular diseases are the main cause of mortality in the world. Diets containing saturated fatty acids, industrial trans fatty acids and unsaturated Cis fatty acids, have different effects on blood lipids, insulin resistance, thrombosis and impaired endothelial cell function. Accordingly, this study aims at measuring the amount of fatty acids in some food products that are com...

Marine diatoms are important sources of fat and fatty acids that are considered for aquaculture and alternative energy sources, and under varying environmental conditions in algae. In order to influence the nitrogen deficiency and light intensity of the medium culture on the C.calcitrans fatty acid composition, algae was exposed to 4 nitrogen treatments (25,50,75 and 100% nitrogen) and light in...
متن کاملDetermination and study the fatty acid contents and their seasonal variations by temperature of a dominant bivalve(Callista umbonella) of Haleh Creek
In this study fatty acid contents, because of the importance in human’s life, and their seasonal variations of a dominant bivalve of Haleh Creek were determined for the first time. Fatty acid identification was done by GC-MS (Gas Chromatography–Mass Spectrometry) method. After collecting and dissecting the species from the shells, samples weighed and frozen for further experiments. All the samp...

The aim of this research was to identify and isolate the fatty acids composition of Nerita textiles in intertidal area of Chabahar Bay, and also to explore the seasonal changes of fatty acid content in Nerita textiles. GC/MS resulted thirteen fatty acids, that saturated fatty acids (SFA) of palmitic acid (16:0) was the most abundant category of fatty acid obtained in total lipids. There were no...
