N-(Phenylsulfonyl)-l-asparagine
In the title compound, C(10)H(12)N(2)O(5)S, one of the sulfonyl O atoms is hydrogen bonded to the amido N atom of an adjacent mol-ecule. There is also a weak hydrogen-bonding inter-action between the other sulfonyl O atom and the secondary amino N atom. In addition, the amido O atom is also hydrogen bonded to a carboxyl O atom. These hydrogen-bonding inter-actions give rise to a layer structure...
متن کاملN-(p-Tolylsulfonyl)-l-asparagine
In the title compound, C(11)H(14)N(2)O(5)S, the amide O atom acts as a hydrogen-bond acceptor from a carboxyl-ate O atom and a secondary amino N atom. In addition, one of the sulfonyl O atoms and the carbonyl O atom of the carboxyl group also form hydrogen bonds with the primary amido N atom. These intermolecular hydrogen-bonding inter-actions give rise to a layer structure, with the layers par...
متن کاملl-Asparagine–l-tartaric acid (1/1)
In the title compound, C(4)H(8)N(2)O(3)·C(4)H(6)O(6), the amino acid mol-ecule exists as a zwitterion and the carb-oxy-lic acid in an un-ionized state. The tartaric acid mol-ecules are linked into layers parallel to the ab plane by O-H⋯O hydrogen bonds. The amino acid mol-ecules are also linked into layers parallel to the ab plane by N-H⋯O and C-H⋯O hydrogen bonds. The alternating tartaric acid...
متن کاملThe biochemical pathway for the breakdown of N4-ethyl-L-asparagine in the bacterium Pseudomonas stutzeri.
N4-Ethyl-L-[u-14C]asparagine and L-[U-14C]aspartate give identical metabolites, mainly intermediates of the tricarboxylic acid cycle and related amino acids, in whole cells of Pseudomonas stutzeri. The labelled asparagine derivative is converted into [14C]-aspartate by cell-free extracts, and this reaction, which has an optimum pH of 8.8 +/- 0.2, is neither inhibited by unlabelled asparagine no...
متن کاملHepatic regulation of plasma L-asparagine.
WOODS, JAMES S., AND ROBERT E. HANDSCHUMACHER. Hepatic regulation of plasma L-asparagine. Am. J. Physiol. 224(4): 74-O-745. 1973.-The hepatic regulation of plasma L-asparagine (Asn) was studied in isolated perfused rat livers. The Asn concentration in the perfusate is rigorously maintained by this organ at 20 PM. Attempts to deplete tissue Asn, normally 500 nmoles/g, by four 1 -hr perfusions wi...
