Chemical Information
FooDB Name19-oxo-testosterone
Description19-oxotestosterone, also known as 19-aldehyde-testosterone, belongs to androgens and derivatives class of compounds. Those are 3-hydroxylated C19 steroid hormones. They are known to favor the development of masculine characteristics. They also show profound effects on scalp and body hair in humans. 19-oxotestosterone is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 19-oxotestosterone can be found in a number of food items such as tree fern, italian sweet red pepper, anise, and atlantic herring, which makes 19-oxotestosterone a potential biomarker for the consumption of these food products. 19-oxotestosterone can be found primarily throughout most human tissues. In humans, 19-oxotestosterone is involved in the androgen and estrogen metabolism. 19-oxotestosterone is also involved in a couple of metabolic disorders, which include 17-beta hydroxysteroid dehydrogenase III deficiency and aromatase deficiency.
