The Structure of Octapeptin D (studies on Antibiotics from the Genus Bacillus. Xxviii)1)
Amino acid analysis of the acid hydrolyzate of octapeptin D revealed the amino acid composition. These amino acids were converted to r.-leucyl-derivatives and analyzed by high performance liquid chromatography to clarify their chiralities. These were determined to he: 2,4-diaminobutyric acid (4L), Ser (o), Leu (2L, 1D). Deacylation with polymyxin acylase afforded deacyl octapeptin D. EDMAN degr...

متن کاملLecture XXVIII: Horizons and the area theorem
We begin by reconsidering the nature of the horizon. As we found in the Schwarzschild case, when properly considered in terms of a set of coordinates that are nonsingular at the horizon (ũ, ṽ, θ, φ), the horizon (in that case, ũ = 0) is actually a 3-dimensional submanifold H of the overall 4D manifold M. This is not surprising since it represents a boundary between the region observable by an o...
متن کاملSTUDIES IN STEROID METABOLISM. XXVIII. THE a-KETO- STEROID EXCRETION PATTERN IN NORMAL FEMALES
An examination of the urinary a-ketosteroids has been made in normal women in order to provide information about this important group of hormone metabolites. These data establish limits of values for the major components of this group of steroids and thus provide not only a suitable comparison for studies in abnormal or altered hormonal physiology, but offer information about possible sex diffe...
متن کاملStudies on Analysis of Pesticide Residues in Foods (XXVIII) Determination of 33 Organophosphorus Pesticides in Agricultural Crops
A modified method for the simultaneous determination of 33 organophosphorus pesticides in agricultural crops was presented. After extraction of samples with acetonitrile, the pesticides are transfered into 20% dichloromethane in benzene, cleaned up by charcoal column chromatography, and then determined simultaneously by the gas liquid chromatography with a flame photometric detector using the c...
