Metabolism and Physiological Effects of N-Acetylhistidine
smpdb.ca/view/SMP0126711MetabolicTechnically, N-Acetylhistidine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-histidine. … The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G).
Drugs: HistidineMetabolism and Physiological Effects of Beta-Alanine
smpdb.ca/view/SMP0126732MetabolicUnder normal conditions, beta-alanine is metabolized into acetic acid. beta-Alanine can undergo a transanimation reaction with pyruvate to form malonate-semialdehyde and L-alanine. … Malonate is then converted into malonyl-CoA and enter fatty acid biosynthesis.
Metabolism and Physiological Effects of 1-Methylhistidine
smpdb.ca/view/SMP0126760Metabolicacid. … As a result, for several decades, many papers incorrectly identified 1MH as a specific marker for dietary consumption or various pathophysiological effects when they really are referring to 3MH – and vice
Intracellular Signalling Through Adenosine Receptor A2a and Adenosine
smpdb.ca/view/SMP0000320SignalingThe A2A receptor is also expressed in the brain, where it has important roles in the regulation of glutamate and dopamine release. … The A2A receptor is responsible for regulating myocardial blood flow by vasodilating the coronary arteries, which increases blood flow to the myocardium, but may lead to hypotension.
Drugs: ATP · Adenosine · Magnesium cation · Zinc · Cyclic adenosine monophosphate · Pyrophosphoric acidIntracellular Signalling Through Histamine H2 Receptor and Histamine
smpdb.ca/view/SMP0000335SignalingHistamine is an organic nitrogenous compound that is involved in local immune responses and it is a neurotransmitter for brain. … Histamine can mediate various actions by interacting with histamine receptors (H1, H2, H3 and H4).
Metabolism and Physiological Effects of Indoxyl glucoside (indican)
smpdb.ca/view/SMP0124742MetabolicAfter being transported into gut microbes, tryptophan undergoes a reaction with the enzyme tryptophanase to form indole. … It is also shown to cause vascular calcification and disrupt the electron transport chain and oxidative phosphorylation causing muscle atrophy.
Metabolism and Phsyiological Effects of Asymmetric dimethylarginine (ADMA)
smpdb.ca/view/SMP0124747MetabolicL-arginine is obtained from protein-rich foods like red meat, poultry, dairy and eggs. It is absorbed in the intestine to the blood. … This elevates blood pressure, causes vasoconstriction, impairs endothelium-dependent relaxation, and increases endothelial cell adhesiveness.
Enzymes: Y+L amino acid transporter 1, Low affinity cationic amino acid transporter 2Metabolism and Physiological Effects of Symmetric dimethylarginine (SDMA)
smpdb.ca/view/SMP0124764MetabolicL-arginine is obtained from protein-rich foods like red meat, poultry, dairy and eggs. It is absorbed in the intestine to the blood. … It enters cells in the body and is metabolized to SDMA via the enzyme protein arginine methyltransferase-5 or protein arginine methyltransferase-7.
