Synthesis of Adenylyl Sulfate and Adenylyl Sulfate 3'-phosphate.
The implication of adenylyl sulfate 3’.phosphate in the synthesis of the sulfated acid mucopolysaccharides has been well documented (l-6). However, the nature of the sulfation step, although studied extensively, is still obscure. Although the introduction of new techniques in nucleotide chemistry has resulted in the synthesis of many of the possible precursors of the acid mucopolysaccharides (7...
متن کاملSynthesis, structure and conductivity of sulfate and phosphate doped SrCoO3
In this paper we report the successful incorporation of sulfate and phosphate into SrCoO3 leading to a change from a 2H– to a 3C–perovskite polymorph. Structural characterization by neutron diffraction showed extra weak peaks related to oxygen vacancy ordering, and these could be indexed on an expanded tetragonal cell, containing two inequivalent Co sites, similar to previously reported for Sb ...
متن کاملDetermination of magnesium by the Titan yellow and ammonium phosphate methods.
The ammonium phosphate and Titan yellow methods for determining magnesium have been investigated, and improvements to both techniques are presented. The Titan yellow method is shown to be subject to interference which makes it unsuitable for the analysis of blood cells, food, and faecal materials, and may also affect its reliability with pathological samples of serum and urine. The relative ins...

2 Abstract In this paper we report the successful incorporation of sulfate and phosphate into SrCoO 3 leading to a change from a 2H– to a 3C–perovskite polymorph.

متن کاملAccumulation of phosphate, sulfate and sucrose by excised Phloem tissues.
Excised petiolar vascular bundles and excised phloem tissues have been shown to take up phosphate, sulfate and sucrose by a true accumulation process and against high concentration ratios. Phosphate was accumulated principally as inorganic phosphate, and sucrose principally as sucrose. The rates of accumulation of the 3 solutes into the phloem-containing tissues were from 4 to 35 times higher t...
