The Present Status of Organic Elemental Microanalysis
The influence of instrumental analysis, i.e., physicochemical methods, has become increasingly important in organic chemistry, but organic elemental microanalysis is by no means an obsolete field. On the contrary, with the development of new methods, the organic chemist obtains the results that he needs for a first orientation on a compound, more quickly and more reliably than ever before. Toda...
متن کاملThe 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...
