Homocysteine and Its Disulfide Derivatives

Homocysteine and its disulfide derivatives: a suggested consensus terminology.

In recent years, there has been an upsurge of interest in elevation of the plasma concentration of homocysteine and closely related metabolites as an independent risk factor for cardiovascular disease (reviewed, for example, in References 1 through 3). Homocysteine itself is a thiol(sulfhydryl-) containing amino acid, but in normal human plasma and other tissues, a variety of related disulfide ...

Cystinuria: Metabolism of the Disulfide of Cysteine and Homocysteine.

Are L-adenosine and its derivatives substrates for S-adenosyl-L-homocysteine hydrolase?

Moffatt oxidation of 2',3'-O-isopropylidene-L-adenosine and treatment of the resulting crude 5'-aldehyde with hydroxylamine followed by deprotection gave L-adenosine 5'-carboxaldehyde oximes, whose enantiomers are known to be potent inhibitors of S-adenosyl-L-homocysteine (AdoHcy) hydrolase. The L-adenosine and its 5'-aldehyde oxime derivatives were found to be inactive as inhibitors of AdoHcy ...

Theoretical Study of Acenaphthylene and its Derivatives

Polycyclic Aromatic Hydrocarbon (PAH) plays an important role in the formation of combustion-generatedparticles such as soot, and their presence in atmosphere aerosols has been widely shown. The formation of five-membered rings, detected in combustion effluent, is of great interest due to their genotoxic activity.The present study reports an investigation of the electronic structure of Acenapht...

Cubes polynomial and its derivatives

Let i (G) be the number of induced i-cubes of a graph G. Then the cubes polynomial c(G; x) of G is introduced as P i0 i (G)x i. It is shown that any function f with two related, natural properties, is up to the factor f(K 1 ; x) the cubes polynomial. The derivation @ G of a median graph G is also introduced and it is proved that the cubes polynomial is the only function f with the property f 0 ...
