Opis ogólny
The Serum Triglyceride Determination Kit is for the quantitative enzymatic measurement of glycerol, true triglycerides, and total triglycerides in serum or plasma at 540 nm. Triglycerides, esters of fatty acids and glycerol,1 do not circulate freely in plasma, but are bound to proteins and transported as macromolecular complexes called lipoproteins.2 Methods for triglyceride determination generally involve enzymatic3 or alkaline4 hydrolysis of triglycerides to glycerol and free fatty acids, followed by either chemical or enzymatic measurement of the glycerol released.
Zastosowanie
A Serum Triglyceride Determination Kit was used to determine the level of triglycerides in whole-body homogenates of Drosophila melanogaster.
The Serum Triglyceride Determination Kit can be used for the measurement of glycerol, true triglycerides, or total triglycerides in serum or plasma. The procedure involves enzymatic hydrolysis by lipase of the triglycerides to glycerol and free fatty acids. The glycerol produced is then measured by coupled enzyme reactions. Many of the triglyceride reagents which are commercially available, do not differentiate between endogenous glycerol and glycerol derived by hydrolytic action of lipase on glycerides.
Triglycerides are first hydrolyzed by lipoprotein lipase to glycerol and free fatty acids. Glycerol is then phosphorylated by adenosine-5′-triphosphate (ATP) forming glycerol-1-phosphate (G-1-P) and adenosine-5′-diphosphate (ADP) in the reaction catalyzed by glycerol kinase (GK). G-1-P is then oxidized by glycerol phosphate oxidase (GPO) to dihydroxy-acetone phosphate (DAP) and hydrogen peroxide (H2O2). Peroxidase (POD) catalyzes the coupling of H2O2 with 4-aminoantipyrine (4-AAP) and sodium
N-ethyl-N-(3-sulfopropyl) m-anisidine (ESPA) to produce a quinoneimine dye that shows an absorbance maximum at 540 nm. The increase in absorbance at 540 nm is directly proportional to triglyceride concentration of the sample.

The triglyceride and free glycerol kits are for the quantitative determination of glycerol, total triglycerides or free triglycerides.
Opakowanie
The kit also includes sufficient reagent for an additional 250 free glyceride tests for true triglyceride determination.

Several inherited metabolic disorders are associated with an accumulation of reactive acyl-CoA metabolites that can non-enzymatically react with lysine residues to modify proteins. While the role of acetylation is well-studied, the pathophysiological relevance of more recently discovered acyl modifications, including

Understanding mechanisms underlying adipogenic differentiation may lead to the discovery of novel therapeutic targets for obesity. Wnt signalling pathway activation leads to repressed adipogenic differentiation while certain microRNAs may regulate pre-adipocyte proliferation and differentiation. We show here that in mouse
