polyunsaturated fatty acid- an unsaturated fatty acid whose carbon chain has more than one double or triple valence bond per molecule; found chiefly in fish and corn and soybean oil and safflower oil ricinoleic acid- an oily fatty acid found in castor oil and used in soap ...
Gα subunit and GTP detached from the GPR40 and attached with effectors molecule PLC. PLC hydrolyzes PIP2 into two second messengers: IP3 and DAG. IP3 bind to the Ins3P receptor (Ins3PR) on a ligand-gated Ca2+ channel that is found on the surface of the ER. The binding of IP3...
saturated fat,any solid fat that is anesterofglyceroland a saturatedfatty acid. The molecules of a saturated fat have only single bonds between carbon atoms; if double bonds are present in the fatty acid portion of the molecule, the fat is said to be unsaturated. Unsaturated fats generally ...
Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are
In addition, treatment with this fatty acid markedly enhanced messenger RNA levels of tumor necrosis factor alpha, monocyte chemoattractant protein 1, vascular cell adhesion molecule 1, and intercellular adhesion molecule 1. Treatment with linolenic acid stimulated only a moderate induction of the genes...
In lipid: Unsaturated fatty acids Unsaturated fatty acids have one or more carbon-carbon double bonds. The term unsaturated indicates that fewer than the maximum possible number of hydrogen atoms are bonded to each carbon in the molecule. The number of double bonds is indicated by the generic…...
This process begins with an oxygen molecule (O2) in the air inserting into carbon-hydrogen (C-H) bonds adjacent to one of the double bonds within the unsaturated fatty acid. 这个过程开始于空气中的一个氧分子(O2)插入到与不饱和脂肪酸中的一个双键相邻的碳-氢(C-H)键中。 WikiMatrix A ...
5.Unsaturated transition metal thiocarbonyl complexes are building blocks for stable organometallic complexes and play important role in catalysis and biology.The CS molecule is isovalent with CO. 饱和过渡金属硫代羰基合物仅在催及生物上具有重要作用,而且这些合物是许多稳定的金属有机合物的结构单元。 声明...
Saturated fatty acids have a zigzag linear structure, which is more attractive and has a higher melting point (the temperature at which solids are converted from solid to liquid). The double bond in the unsaturated fatty acid is a cis structure, the molecule is curved, the structure is relati...
Highly unsaturated fatty acids (HUFAs) are fatty acids with more than three double bonds in the molecule. Mammalian testes contain very high levels of omega-6 HUFAs compared with other tissues. However, the metabolic and biological significance of these HUFAs in the mammalian testis is poorly ...
