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).
Denaturing of enzymes. The important part of an enzyme is called the active site. This is where specific molecules bind to the enzyme and the reaction occurs. Anything that changes the shape of the active site stops the enzyme from working.This is similar to a key that opens a door lock.he important part of an enzyme is called the active site.
