Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

unit 4222- 265 1 1.1: identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria are living things that are neither plants nor animals‚ but belong to a group all by themselves. They are very small--individually not more than one single cell--however there are normally millions of them together‚ for they can multiply really fast.Bacteria are prokaryotes (single cells that do not contain a nucleus). Every species has a great ability to produce offspring and its population

2.1 Synthesis of p-Toulichydrazone and Resacetophenone Schiff base (RAPPTH): p-Toluic hydrazide (1.5018g) and Resacetophenone (2‚4Dihydroxyacetophenone)(1.5215g) were dissolved in methanol and Refluxed in the presence of few drops of acetic acid for 7 hours on water bath with constant stirring. The resultant mixture was transferred in a china dish and allowed to cool naturally. Light brown crystals were obtained. The compound was recrystalized from water. The % of yield was 80%

Alternative cancer therapies are an emotive subject. In this Summative assessment the main events in a hypothetical case history are recounted from a naturopathic point of view and an effective management plan for the final part of the nutritional treatment is described. To support the given treatment strategy an attempt is made to subjectively consider a critique of nutritional therapies in general and the Gerson cancer therapy in particular‚ written by Saul Green PhD‚ biochemist and science editor

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

C. partellus gut protease and protease inhibitor activity assays. C. partellus gut protease activity was estimated using chromogenic substrate BApNA [Manasi A et al.‚ 2005]. It was dissolved in the DMSO and a final concentration was made to 1mM in 1.0ml‚ Glycine-NaOH buffer (pH 9)‚ assays were carried at 38°C for 30min [Manasi A et al.‚ 2005]. The reaction was terminated by adding of acetic acid (30%) of 200µl [8‚ 9‚ Manasi A et al.‚ 2005 ]. Supernatant (0.5ml) was added to 1M NaOH (0.5ml) and the
