Reactions of Aldehydes and Ketones Introduction In this experiment, many tests were performed on an unknown to determine its identity. The tests that were used include: Tollens Test, Iodoform Test, and the preparation of solid derivatives with the use of both 2,4 – dinitrophenylhydrazone and semicarbazone1. The reactivity of the carbonyl group is utilized in this experiment. The structure of a carbonyl group and the […]

Abstract Nanotechnology is concerned with manipulating matter to near atomic scales between one and 100nm (nanometers-1 billionth of a meter). This technology has recently gained popularity due to its potential in altering the behaviour of individual molecules and has opened the door to new applications. Many researchers have pinpointed the potential risk of nanotechnology on the environment and on human health. This is due to […]
1. INTRODUCTION Surfactants are surface active compound that reduce the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants are organic compound that contain both hydrophobic (head part of the surfactant) and hydrophilic (tail part of the surfactant) moieties. Thus surfactant contains both water insoluble i.e. water repellent group as well as water soluble i.e. water loving group. Biosurfactants are […]
SIMULTANEOUS ESTIMATION OF SALBUTAMOL SULPHATE AND GUAIPHENESIN IN THEIR COMBINED LIQUID DOSAGE FORM BY HPTLC METHOD Kruti D. Bhalara, Ishwarsingh S. Rathod, Sindhu B. Ezhava, Dolarrai D. Bhalara, ABSTRACT A simple, specific, sensitive and validated high-performance thin layer chromatographic (HPTLC) method was developed for the simultaneous analysis of Salbutamol sulphate and Guaiphenesin. Spectro-densitometric scanning-integration was performed at an absorbance wavelength 280 nm. A TLC aluminium […]

Induced Change in Gene Expression of Mitochondrial Enzymes as a Result of Intense Exercise Abstract Exercise-induced changes in gene expression of mitochondrial enzymes has become a leading target for sports medicine research. Previous indirect testing of delayed-onset muscle soreness and changes in rotation of motion do not provide a sufficient explanation of the induced changes to the genome (Hubal, et al., 2010). Biomarker testing has […]
