Modes of Fatty Acid Desaturation in Cyanobacteria: An Update
نویسندگان
چکیده
Fatty acid composition of individual species of cyanobacteria is conserved and it may be used as a phylogenetic marker. The previously proposed classification system was based solely on biochemical data. Today, new genomic data are available, which support a need to update a previously postulated FA-based classification of cyanobacteria. These changes are necessary in order to adjust and synchronize biochemical, physiological and genomic data, which may help to establish an adequate comprehensive taxonomic system for cyanobacteria in the future. Here, we propose an update to the classification system of cyanobacteria based on their fatty acid composition.

Evaluation of the nutritive value of wild almond seed (Amygdalus scoparia) and its effect on performance, milk fatty acid composition and antioxidant activity in lactating goats
A total of 21 dairy goats in mid lactation were randomly assigned to three experimental diets in a completely randomized design. The diets contained 0, 3, or 6% WAS, and consisted of 45% forage and 55% concentrates. Milk fat and the ratio of milk fat to milk protein were significantly lower in goats fed diets containing 6% WAS (P≤0.01). Digestibility of crude fat was higher, and that of neutral...
متن کاملComparative Analysis of Fatty Acid Desaturases in Cyanobacterial Genomes
Fatty acid desaturases are enzymes that introduce double bonds into the hydrocarbon chains of fatty acids. The fatty acid desaturases from 37 cyanobacterial genomes were identified and classified based upon their conserved histidine-rich motifs and phylogenetic analysis, which help to determine the amounts and distributions of desaturases in cyanobacterial species. The filamentous or N(2)-fixin...

Objective(s): Weight gain and metabolic disturbances such as dyslipidemia, are frequent side effects of second-generation antipsychotics, including olanzapine. This study examined the metabolic effects of chronic olanzapine exposure. In addition, we investigated the hepatic fatty acid effects of olanzapine in female C57BL/6J mice fed a normal diet.Materials and Methods: Female C57BL/6J mice ora...

Global warming due to fossil fuel, price increases, environmental pollution resulting from their use and production green house gases caused scientists trying to produce proper fuel, renewable of replacing fossil fuels. The purpose of this study was to determine the conditions of survival, growth, pigments and fatty acid profiles to biodiesel production from cyanobacteria Synechococcus ISC 106 ...
متن کاملSelenium compounds for fish health: An update
Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.
