Spectral changes during metabolism of protocatechuic acid (PCA) by the cell-free extract of di-(2-ethylhexyl) phthalate (DEHP)-grown cells of strain MBM. The sample and reference cuvettes contained 50 mM potassium phosphate buffer (pH 7.0) in 1-mL volume. The sample cuvette contained 97 nmol...
A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indicat...
Figure 33.1.Molecular structure of alkyl sulfate salt. This structure shows sodium dodecyl sulfate. SDS has excellent foaming properties regardless of water hardness.7AS commonly includes small amounts of fatty alcohol, which is the raw material, as an impurity. This impure AS product actually has...
The effect of pH on the activity of CmER was determined by assaying the enzyme activity at various pH values (pH 4.0 - 9.0). The reactions were carried out at 37°C in the following buffer systems and pH values: sodium citrate buffer (pH 4.5 - 6.0), potassium phosphate buffer (pH ...
