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.

(levocarnitine) is a carrier molecule in the transport of long-chain fatty acids. across the inner mitochondrial membrane. R. )-hydroxy-N,N,N-trimethyl-1Â­. propanaminium, inner salt. Levocarnitine is a white crystalline, hygroscopic powder. It is. readily soluble in water, hot alcohol, and insoluble in acetone. , calculated after correction for circulating endogenous plasma concentrations of levocarnitine, was 15.1 Â± 5.3% for CARNITOR Â® Tablets and 15.9 Â± 4.9% for CARNITOR Â® Oral Solution. Total body clearance of levocarnitine (Dose/AUC including endogenous baseline concentrations) was a mean of 4.00 L/h.
