Anwendung

L-Homocysteic acid has been used to study hydrogen peroxide-mediated changes in physiological and pathological conditions in the nervous system.

Biochem./physiol. Wirkung

L-Homocysteic acid (L-HCA) is an endogenous neurotransmitter ligand of NMDA (N-methyl-D-aspartate) receptors. It is an analog of glutamate and competitively suppresses glutamate-cystine (xc-) antiporter function in neurons, causing decrease in cysteine uptake.

Fast photochemical oxidation of proteins (FPOP) is a MS-based method that has proved useful in studies of protein structures, interactions, conformations, and protein folding. The success of this method relies on the irreversible labeling of solvent-exposed amino acid side chains

The effects of ionophoretically applied L-homocysteate (L-HCA), L-glutamate (L-Glu) and N-methyl-D-aspartate (NMDA) were compared in rat neocortical neurons recorded intracellularly in vitro. The firing pattern and the time course of membrane depolarization induced by L-HCA resembled those of NMDA responses.

L-Homocysteic acid (L-HCA) has been proposed as a natural transmitter at the N-methyl-D-aspartate (NMDA) subtype of excitatory amino acid receptor based on recent evidence that L-HCA occurs L-HCA occurs naturally in the mammalian CNS, is released from K+ stimulated brain

Changes in cardiorespiratory control accompany the expression of complex emotions, indicative of limbic brain inputs onto bulbar autonomic pathways. Previous studies have focussed on the role of the prefrontal cortex in autonomic regulation. However, the role of the hippocampus, also

The role of homocysteic acid (HCA) in severe diseases like Alzheimer's disease is under discussion and some recent studies correlate elevated HCA concentrations with the diagnosis of Alzheimer's. However, non-selective and insufficiently sensitive methods have been used to quantitate HCA
