Content Methods of study overlap both of the above areas, emphasizing analytical methods to determining if a steroid is current in a combination and determining its quantity. Progestogens are the precursors of all other human steroids, and all human tissues which produce steroids must first convert cholesterol to pregnenolone. This conversion is the rate-limiting step of steroid synthesis, which occurs inside the mitochondrion of the respective tissue. In subsequent steps DMAPP and IPP conjugate to type farnesyl diphosphate , which…
