FIGURE 2 In 1976 Benson and Talalay discovered that the cytosolic fraction of rat liver catalyzes the same steroid isomerization of 5-androsten-3,17-dione, but in distinction from the bacterial enzyme the reaction included reduced glutathione as a designated coenzyme ( 1 mg 1 ) in comparison with the five orders of magnitude higher activity of the Pseudomonas enzyme ( In retrospect, it is clear that the ketosteroid isomerase activity of the GST in human liver ( 1 B 1 and B 1 B 2 in Mechanism of Ketosteroid Isomerase Catalyzed by Mammalian Glutathione Transferases The double-bond isomerization of ketosteroids has been investigated with 5-AD and 5-PD (Figure 2)

Mood balance : Plays a role in neurotransmitter regulation, reducing feelings of low mood
higher frailty with low IGF-1, potentially higher CVD risk, lesser cancer risk, but lower frailty with hi T, that are contrasting aspects at least partly
Epithalon is a tetrapeptide that works through the pineal gland to regulate melatonin and circadian rhythm
Studies have reported that the interaction of AFs and DNA causes significant damage to DNA and associated biological processes such as transcription and chromatin packaging (280)
