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.

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

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 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.

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

Combining with the neurotransmitter dopamine to initiate a change in cell activity.

Combining with an icosanoid to initiate a change in cell activity.

Combining with a prostanoid, any compound based on or derive4d from the prostanoate structure, to initiate a change in cell activity.

Combining with a prostaglandin (PG) to initiate a change in cell activity.

Combining with prostaglandin D (PGD(2)) to initiate a change in cell activity.

Combining with prostaglandin E (PGE(2)) to initiate a change in cell activity.

A proteinaceous core found between sister chromatids during meiotic prophase.

Combining with prostaglandin F (PGF (2-alpha)) to initiate a change in cell activity.

A structural unit of the synaptonemal complex found between the lateral elements.
