Molecular interaction of AAS with androgen receptors
Anabolic steroids influence cellular differentiation while favoring the development of muscle cells over fat-storage cells. Research in this field has shown that structural modifications in anabolic steroids are critical in determining their binding affinity to ARs and their resulting anabolic and androgenic activities. These modifications affect a steroid's ability to influence gene expression and cellular processes, highlighting the complex biophysical interactions of anabolic steroids at the cellular level.
