19-Noretiocholanolone
19-Noretiocholanolone (pronunciation: 19-noh-ree-oh-choh-lan-oh-lohn) is a steroid metabolite that is derived from testosterone. It is also known as 19-norandrosterone and is a major urinary metabolite of nandrolone.
Etymology
The term "19-Noretiocholanolone" is derived from the Greek words "nore" meaning "without", "etio" meaning "cause", "cholane" meaning "bile", and "olone" referring to the steroid structure. The "19" refers to the position of the carbon atom that is missing a methyl group compared to testosterone.
Chemistry
19-Noretiocholanolone is a C19 steroid and is structurally similar to testosterone, but lacks a methyl group at the 19th position. This structural difference results in a steroid with slightly different properties compared to testosterone.
Pharmacology
19-Noretiocholanolone is a metabolite of nandrolone, an anabolic steroid used in medicine to treat conditions like anemia and osteoporosis. The presence of 19-Noretiocholanolone in urine can be used as an indicator of nandrolone use.
