Biotransformation of oral contraceptive ethynodiol diacetate with microbial and plant cell cultures

UNLABELLED BACKGROUND Biotransformation by using microbial and plant cell cultures has been applied effectively for the production of fine chemicals on large scale. Inspired by the wealth of literature available on the biotransformation of steroids, we decided to investigate the biotransformation of ethynodiol diacetate (1) by using plant and microbial cultures. RESULTS The biotransformati...

The Colorimetric Determination of Hexosey with Carbazole

The difficulty of applying classical procedures to the qualitative and quantitative determination of carbohydrate in certain biological materials has led to the development of calorimetric methods in which the carbohydrate-containing material is treated with strong mineral acids, causing t,he formation of substances which will react with compounds such as diphenylamine, resorcinol, orcinol, ind...

Colorimetric Determination of Serum

In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...
