Description

Analysis of Sterols and Other Biologically Significant Steroids provides the fundamental training for the analysis of selected sterols and steroids.

The book is composed of chapters that review the spectroscopic and chromatographic properties of certain sterols and steroids. The text also teaches how to isolate and characterize sterols and steroid metabolites of plant, fungal, and insect origin. Lipoprotein analysis and the utilization of physical-analytical techniques are likewise provided.

Biochemists, microbiologists, and medical physiologists will find the book useful.
