Steroid Chemistry

Steroid immunoassay in clinical chemistry.

Steroid immunoassay is in a state of transition from being purely a research tool to being an indispensable aid in clinical diagnosis. Because immunochemical methods were first used for the assay of steroid hormones, this type of assay (in the form of radioimmunoassay) has been used extensively in clinical research. The results of this research have transformed the field of steroid endocrinolog...

Bismuth(III) reagents in steroid and terpene chemistry.

Steroid and terpene chemistry still have a great impact on medicinal chemistry. Therefore, the development of new reactions or "greener" processes in this field is a contemporaneous issue. In this review, the use of bismuth(III) salts, as "ecofriendly" reagents/catalysts, on new chemical processes involving steroids and terpenes as substrates will be focused. Special attention will be given to ...

Steroid Hormones: Membrane transporters of steroid hormones

The discovery of a plasma membrane ABC protein that exports steroids in yeast highlights the possibility that similar membrane sorting systems in mammalian cells may modulate the access of steroids to their receptors.

Microencapsulation in Food Chemistry

Encapsulation, invented in 1953 by B.K. Green & L. Schleicher employed in the laboratories of the National Cash Register Company, Dayton, USA, is defned as a technology of packaging solids, liquids, or gaseous materials in miniature, sealed capsules that can release their contents at controlled rates under specifc conditions. Encapsulation involves the incorporation of ...
