The Absorption of Ultra-violet Radiation by Crystalline Pepsin
Determination of the absorption spectra of pure preparations of Northrop's crystalline pepsin inactivated by irradiation with ultra-violet light shows that the total absorption in the ultra-violet region of the spectrum increases with the degree of inactivation. This increase is especially marked between 2400 and 2750 A.u. The rate of photoinactivation is shown to be sensitive to changes in pH,...

times that needed to denature egg albumin, using the estimate given by Mirskyl2 or fifty times the energy needed for the inactivation of certain ionic forms of pepsin according to Steinhardt's determinations."3 The denaturation of egg albumin by ultra-violet light is a first order reaction,'4 i.e., the survival curve is a straight line similar to that obtained for chromosome abnormalities. It s...
متن کاملSimultaneous Determination of Six Benzodiazepines in Spiked Soft Drinks by High Performance Liquid Chromatography with Ultra Violet Detection (HPLC-UV)
A high performance liquid chromatographic method with ultra violet detection for simultaneous analysis of six benzodiazepines (BZDs) (chlordiazepoxide, diazepam, clonazepam, midazolam , flurazpam and lorazepam) has been developed for forensic screening of adulterated non-alcoholic drinks. Samples were analyzed after a simple procedure for preparation using pH adjustment and filtering. Isocratic...

متن کاملThe Effect of Radiations from a Mercury Arc in Quartz on Enzymes
Amylase in solution is inactivated by the radiations from a mercury arc in quartz, in a manner similar to that previously reported for pepsin. The reaction was followed to a point where more than 88 per cent change had taken place, the course being that of mono-molecular radiochemical change. Apparently, this reaction is due to the influence of ultra-violet radiation alone.
