WebMar 7, 2024 · Homocysteine (Hcy) is an important intermediate product produced during the metabolism of methionine, known as the methionine cycle. As shown in Figure 1, Hcy and methionine can be converted into each other. This conversion mechanism depends on folate and vitamin B12 (VB12). WebDec 9, 2024 · Glutamate and homocysteine are both differentially expressed metabolites in the studies of metabolomics, and they can both induce inflammatory responses in the retina.

Astaxanthin Protects PC12 Cells against Homocysteine
WebL-Homocysteine and its alpha-keto acid analog were shown to be substrates of glutamate dehydrogenase and kidney glutamine transaminase. DL-Homocysteine reacts readily with alpha-keto acids to form stable hemithioketals, which were found to be substrates of L- and D-amino acid oxidases. WebHomocysteine is further processed via the transsulfuration pathway into the amino acid cysteine. Two more reactions are required to produce the GSH tripeptide from cysteine. First, the enzyme γ-glutamylcysteine synthetase (γGSC) combines cysteine with glutamate to form γ-glutamylcysteine. WebThus, the two substrates of this enzyme are 5-methyltetrahydropteroyltri-L-glutamate and L-homocysteine, whereas its two products are tetrahydropteroyltri-L-glutamate and L … todai buffet in chicago
