Colors as Catalysts in Enzymatic Reactions

We studied the effects of visible range irradiation (in vitro) on the enzyme solutions (glucose oxidase, cholesterol oxidase + cholesterol esterase and lipase) in order to infer the changes produced in the human body after chromotherapy. The glucose oxidase showed enhanced activity to the color purple (464 nm), while the activity of the other enzymes, cholesterol esterase + cholesterol oxidase and lipase, increased when exposed to dark violet (400 nm). Purple is being used in conventional chromotherapy for diabetes, as supported by the experimental observation in which purple enhanced the activity of enzymes responsible for the oxidation of glucose. Specific wavelengths regulate living processes by acting as catalysts in enzyme activity, while some wavelengths may reduce enzyme activity. The irradiation of specific wavelengths effect enzymatic processes, which as a consequence, accelerated biochemical reactions. This particular frequency when provided to the enzymes (in vitro) lead to changes which may well be occurring in vivo.

The toxic and carcinogenic organic compounds discharge from industries, contaminate the natural reservoirsof water and air which eventually pose a global threat not only to the aquatic life but also to thehumanity. Herein, ternary nanocomposites of silver-nanoparticle (AgNPs)-decorated on polyaniline(Pani)-wrapped zinc oxide nanorods (AgNPs@Pani/ZnO) were prepared via a facile approach. Thenanocomposite degraded 97.91% phenol with an optimized dosage and concentration of H2O2. Moreover, the apparent rate constant for phenol degradation was 3.69 times higher than for pure ZnOnanorods. The hydrogen production from AgNPs@Pani/ZnO was 1.58 and 2.74 times higher than Pani/ZnO and ZnO, respectively. The enhanced phenol degradation and hydrogen production is attributed tothe transfer of holes to the Pani, from which the electrons were transferred to the conduction band ofZnO and eventually to the conduction band of the AgNPs, where they accelerated the redox reactionsfor rapid photolysis of water and phenol. The concentration of the catalyst dosage affected the rate ofphenol degradation. Further, response surface methodology was also applied in order to design 13 setsof random experiments in which the catalyst dosage and degradation time were varied to predict thephenol degradation.
