Steroid Conjugates and Their Physiological Role
Original language description
While there are hundreds of synthetic steroids conjugates with acids, sugars, proteins and other molecules, only two types of conjugates occur in living organisms, namely sulfates and glucuronides. Steroid glucuronidation in the human liver is the main mechanism controlling the levels and biological activity of unconjugated hormones, and glucuronides are their main excretion products. This process is generally irreversible. On the other hand, sulfates possess their own biological activity that differs from that of the unconjugated steroid, emphasizing the importance of steroid sulfatases and sulfotransferases. Due to their negative charge, steroid sulfates cannot cross the blood-cell barrier and have to use transporters. Their efflux is mediated by specific transporters of the ATP binding cassette protein group, which thus are further factors controlling their physiological as allosteric modulators of some neurotransmitter receptors, functioning as ion channels, such as gamma-aminobutyric acid, type A (GABAA) receptors or N-methyl-D-aspartate (NMDA) coupled receptors (GPCR), which we believe show the way of genomic effect.
