Summary Summary. Acute intermittent porphyria (AIP) is one of the liver (hepatic) porphyrias. AIP is caused by low levels of porphobilinogen deaminase (PBGD), an enzyme also often called hydroxymethylbilane synthase.
Pyridine-N-oxide is the heterocyclic compound with the formula C 5 H 5 NO. This colourless, hygroscopic solid is the product of the oxidation of pyridine. It was originally prepared using peracids as the oxidising agent. The molecule is planar.yridine-N-oxide is the heterocyclic compound with the formula C 5 H 5 NO.

The chemical formula for Pyrite is FeS2 (Iron sulphide). It is a naturally occurring mineral; it is the most abundant Sulphide mineral on the earth. Pyrite or iron pyrite is also used to name Iron sulphide.Also, Foolâs gold is another name for Pyrite. The word Pyrite is a Greek word; the word pyr means fire. In early days, this had been used to make fire by striking against metal or any other hard material.owever, when you closely monitor the color of these two materials, gold and pyrite, the difference between gold and pyrite can be understood easily. It is the first simple method of distinguishing one from another.
