RE: Random vs. Form-wound stator coils for IFDs. Simply buy a motor that is rated for the service it is to perform. In North America, that would be a motor with an MG1 Part 31 endorsement on the nameplate. I'm not familiar with similar endorsements in the IEC world but there may well be one or more.
5a-Reductase (5AR) is the enzyme that catalyzes the conversion of (among others): 1  Testosterone â 5a-DHT. 2  Androstenedioneâ androsterone. 3  Cortisol â allo-tetrahydrocortisol.s early as 1986, it was suspected by some that 5a-DHT might be a primary contributing factor to prostate cancer growth. 15 5a-Reductase (5AR) is responsible for conversion of testosterone to 5a-dihydrotestosterone (5a-DHT).
Human ecto-5'-nucleotidase (CD73): crystal form I (open) in complex with adenosine. 5'-nucleotidase (EC 3.1.3.5) is an enzyme which catalyzes the phosphorylytic cleavage of 5'nucleotides. Although originally found in snake venom, the activity of 5'nucleotidase has been described for bacteria and plant cells, and is widely distributed in vertebrate tissue.
