Sulphur-containing Amino-Acids and Jaundice

The biochemistry and pharmacology of excitatory sulphur-containing amino acids.

1,-Glutamate is now well established as the predominant transmitter at fast-acting excitatory synapses in the mammalian central nervous system. Other amino acids such as L-aspartate and several acidic sulphur-containing amino acids (SAAs) which exhibit potent depolarizing actions similar to that of Lglutamate [I-31 are known to exist in the brain and/or are present in the brain under pathologic...

The nitrogen-sparing effect of methionine sulphoxide and some other sulphur-containing amino acids.

The nitrogen-sparing effect of methionine, methionine sulphoxide, homocystine, cystine and choline was studied in rats by determining dialy N excretions during 5 d after changing from a high-protein diet to a protein-free diet, L-glutamic acid was used as a negative control. 2. L-, D- and DL-methionine were equally active in sparing N. L-methionine sulphoxide, DL-homocystine and L-cystine were ...

Effect of aliphatic, monocarboxylic, dicarboxylic, heterocyclic and sulphur-containing amino acids on Leishmania spp. chemotaxis.

In the sand-fly mid gut, Leishmania promastigotes are exposed to acute changes in nutrients, e.g. amino acids (AAs). These metabolites are the main energy sources for the parasite, crucial for its differentiation and motility. We analysed the migratory behaviour and morphological changes produced by aliphatic, monocarboxylic, dicarboxylic, heterocyclic and sulphur-containing AAs in Leishmania a...
