Histamine: is a heterocyclic primary amine derived from the decarboxylation of the amino acid histidine. Histamine is the primary inflammatory response mediator that is released from either mast cells, or basophilic leukocytes. The amount of histamine released or maintained in the body can vary on factors such as anaphylaxis or diseases. Under normal physiological conditions, the amount of histamine is within a range of 0.3- 1.0ng/mL. The amount of histamine that an individual with stable coronary artery disease may have can be in the range of 90-120ng/mL. Histamine increases smooth muscle cell proliferation which results in intimal thickening and atherogenesis. Component: Histamine C5H9N3 O Calculate the molar mass of Histamine O If a molecule of histamine contains 1.86X 1015 atoms of nitrogen per ml of blood, how many ng of histamine are needed for an individual with stable coronary artery disease? Write something you learned about Histamine Molar Mass Work NH2 Solution
