test) with the oxidation of aromatic protein residues. The Lowry method is best used with protein concentrations of 0.01–1.0 mg/mL and is based on the reaction of Cu+‚ produced by the oxidation of peptide bonds‚ with Folin–Ciocalteu reagent (a mixture of phosphotungstic acid and phosphomolybdic acid in the Folin–Ciocalteu reaction). The reaction mechanism is not well understood‚ but involves reduction of the Folin reagent and oxidation of aromatic residues (mainly tryptophan‚ also tyrosine). Experiments

and expressed it within Escherichia coli as a soluble holoprotein. UV-visible and resonance Raman spectra of gCYTb5-I resemble those of microsomal cytochrome b5‚ and homology modelling supports a structure in which a pair of invariant histidine residues act as axial ligands to the haem iron. The reduction potential of gCYTb5-I is 165 mV vs. SHE and is relatively low compared to most values (110 to +80 mV) for this class of protein. The amino- and carboxy-terminal sequences that flank the central

experiment was to look for the percentage composition of the elements present in the decomposition of potassium chlorate (KClO3) and to find out what the residue after heating was. After performing the experiment the researchers found out that there were about 66.14% of potassium chloride (KCl) in KClO3‚ and they also deducted that the residue was actually KCl. _____________________________________________________________________________________ Introduction Total mass of the Element/Compound
