The formation from simpler components of icosanoids, any of a group of C20 polyunsaturated fatty acids.

The formation from simpler components of prostanoids, any compound based on or derived from the prostanoate structure.

Enables the directed movement of heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring, into, out of, within or between cells.

Enables the directed movement of pantothenate into, out of, within or between cells. Pantothenate is the anion of pantothenic acid, the amide of beta-alanine and pantoic acid; it is a B complex vitamin that is a constituent of coenzyme A and is distributed ubiquitously in foods.

The chemical reactions involving fatty acids with a chain length of less than 8 carbons.

Enables the directed movement of thiamin into, out of, within or between cells. Thiamin is vitamin B1, a water soluble vitamin present in fresh vegetables and meats, especially liver.

Enables the directed movement of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom, into, out of or within a cell.

Enables the directed movement of a drug into, out of, within or between cells. A drug is any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.

Enables the directed movement of drugs into, out of, within or between cells.

The chemical reactions involving para-aminobenzoic acid, an intermediate in the synthesis of folic acid, a compound which some organisms, e.g. prokaryotes, eukaryotic microbes, and plants, can synthesize de novo. Others, notably mammals, cannot. In yeast, it is present as a factor in the B complex of vitamins.

The chemical reactions involving heterocyclic compounds, those with a cyclic molecular structure and at least two different atoms in the ring (or rings).
