A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. Mechanical...

The process called biohydrogenation occurs mainly in ruminant animals and during it, unsaturated fatty acids, and particularly poly-unsaturated ones (linoleic and linolenic) coverts to a saturated form of stearic acid. For many years, the beneficial effects of biohydrogenation intermediate fatty acids like cis-9 trans-11 linoleic acid, the main natural isomer of conjugated linoleic acids (CLA),...

The use of poly unsaturated fatty acids has pronounced significant effects on the efficiency of male reproductive system. Poly unsaturated fatty acids like docosahexaenoic acid, omega 3, Omega 6, oleic and linolinic acid are rich in diets like flaxseed oil, soybean oil, fish oil, sunflower oil. These diets have the capability to increase serum testosterone level, fertility rate, ejaculation per...

The present study was conducted to evaluate the effect of low-dose gamma irradiation (0, 1, 3 and 5 kGy) on fatty acid composition of Rainbow trout (Oncorhynchus mykiss) fillet. Among all of the fatty acids, oleic acid (C18:1) (with mean 33.50±3.02 g/100 g fatty acids) and myristoleic acid (C14:1) (with mean 0.41±0.26 g/100 g fatty acids) were the most predominant and the lowest fatty acids in ...

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...

Unsaturated polyesters have several applications in organic chemistry such as click reaction, radical reaction, etc. In this research, in the first step, a new and inert type of unsaturated binder containing internal alkyne groups was synthesized. For this purpose, condensation polymerization of 2-butyne-1,‌4-diol, and DL-malic acid was performed at 130 °‌C without solvent. Thermal properties w...
