The chemical reactions involving leukotriene, a pharmacologically active substance derived from a polyunsaturated fatty acid, such as arachidonic acid.

Combining with histamine to initiate a change in cell activity. Histamine is a physiologically active amine, found in plant and animal tissue and released from mast cells as part of an allergic reaction in humans.

The chemical reactions involving prostanoids, any compound based on or derived from the prostanoate structure.

The chemical reactions involving prostaglandins, any of a group of biologically active metabolites which contain a cyclopentane ring due to the formation of a bond between two carbons of a fatty acid. They have a wide range of biological activities.

The formation from simpler components of steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus.

The formation from simpler components of cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

The process by which a toxin or poisonous compound or other is rendered harmless.

Catalysis of the reaction: alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3-N-acetyl-D-galactosaminyl-R + CMP-N-acetylneuraminate = alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3-(alpha-N-acetylneuraminyl-2,6)-N-acetyl-D-galactosaminyl-R + CMP.

Combining with chemokines, small chemoattractant molecules normally used to stimulate leukocytes, to initiate a change in cell activity.

cystic fibrosis transmembrane conductance regulator

Catalysis of the reaction: ATP + H2O = ADP + phosphate. An animal enzyme that is active in forming a chloride channel, the absence of which brings about cystic fibrosis. It is also involved in the functioning of other transmembrane channels.

Catalysis of the reaction: cytolipin-H + CMP-N-acetylneuraminate = GM3 + CMP.

The formation from simpler components of bile acids, any of a group of steroid carboxylic acids occurring in bile.

Combining with cholecystokinin, a 33-amino acid peptide secreted by the upper intestinal mucosa and also found in the central nervous system, to initiate a change in cell activity.
