      Cis-Trans Isomeric Carotenoids, Vitamins A, and Arylpolyenes focuses on the reactions, characteristics, and properties of cis-trans isomeric carotenoids, vitamins A, and arylpolyenes. The publication first takes a look at carotenoids, number, types, and properties of cis carotenoids, and cis-trans isomerism and UV spectra. Discussions focus on simple theoretical interpretation of spectral phenomena, spectra at extremely low temperatures, relative stabilities, melting points, rotatory power, and historical remarks on the stereoisomerism of polyenes. The text then ponders on the preparation of cis carotenoids by direct rearrangement of the all-trans form and total synthesis and naturally occurring cis and polycis carotenoids. The manuscript examines some general remarks on configurational assignments, configurational assignments in certain stereoisomeric sets, and lower-molecular weight carotenoid-carboxyli... acids. Topics include bixin set, stereoisomeric sets with two aromatic terminal groups, stereoisomeric sets with one hydroaromatic and one aliphatic terminal group, configuration and infrared spectrum, and stereoisomeric types. The manuscript also elaborates on vitamins A and retinenes, cumulenes with aromatic terminal groups, and polyene azines. The publication is a dependable source of information for researchers interested in cis-trans isomeric carotenoids, vitamins A, and arylpolyenes.

      Advances in Steroid Biochemistry and Pharmacology, Volume 4 provides information pertinent to the fundamental aspects of steroid biochemistry and pharmacology. This book covers a variety of topics, including cellular biochemistry, pituitary hormones, corticosteroids, and steroid hormones. Organized into seven chapters, this volume begins with an overview of the potential effects of steroids on cellular biochemistry. This text then examines the development of sleep-monitoring methods, together with methods of plasma sampling that enable very frequent specimen to be taken without disturbing the subject. Other chapters consider the usefulness of sleep-related growth hormone release in diagnosis in both children and adult. This book discusses as well the versatile effect of corticosteroids on the cellular components of the connective tissue. The final chapter deals with the functioning of the adrenal cortex and its control by adrenocorticotropic hormone (ACTH). This book is a valuable resource for biochemists, histochemists, biologists, pharmacologists, clinicians, and experimental endocrinologists.
