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/SMP0124742MetabolicHartnup disease is an autosomal recessive metabolic disorder affecting the absorption of nonpolar amino acids (particularly tryptophan), which leads to excessive bacterial fermentation of tryptophan (to … 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.
Enzymes: Y+L amino acid transporter 1Intracellular Signalling Through Adenosine Receptor A2b and Adenosine
smpdb.ca/view/SMP0000321SignalingAdenosine is thought to play a role in the pathophysiology of asthma. Stimulation of A2B can induce production of interleukin-8 mast cells. The adenosine receptor A2b activates G(s) proteins which lead to the activation of adenylyl cycla...
