ABSTRACT: Two new coloured mixed ligand complexes of transition metal Cobalt ( 27 Co) with 1,10 - phenanthroline and Sarcosine (N - methyl glycine - an amino acid) as ligand have been prepared, using Methanol or Ethanol as a solvent in mole ratio (1: 2: 1) respectively, at room temperature.
Effects of various metal ions and chemical reagents on amylase activity: The effects of metal ions (Ba2+, Co2+, Mn2+, Ni2+, Zn2+, Mg2+, Ca2+, Cu2+, Hg2+, Fe3+and K+) and the chemical reagents [1, 10 phenanthroline monohidrat, sodium sulfite (Na2SO3), sodium azide (NaN3), ethylenediaminetetraacetic acid (EDTA), phenylmethylsulfonyl fluoride (PMSF), urea, b-mercaptoethanol, Triton X-114, sodium dodecyl sulfate (SDS)] on the amylase activity were investigated by pre-incubating the enzyme in the presence of substances with final concentrations of 10 mM for 15 min at 45 C, and then performing the assay in the presence of the same substances at the optimum temperature (Aygan and Arikan, 2009).
Iron and manganese concentrations were determined by phenanthroline spectrophotometry (China MEP, 2007a) and formaldehyde oxime spectrophotometry, respectively (China MEP, 2007b).
