5-alpha Reductase - Function

Function

5α-reductases convert testosterone, the male sex hormone, into the more potent dihydrotestosterone:

  • Testosterone.

  • Dihydrotestosterone

Note the major difference — the Δ4,5 double-bond on the A (leftmost) ring. (The other differences between the diagrams are unrelated to chemical structure.)

These enzymes also participate in the creation of such neurosteroids as allopregnanolone and THDOC.

Famous quotes containing the word function:

    “Nobody seriously questions the principle that it is the function of mass culture to maintain public morale, and certainly nobody in the mass audience objects to having his morale maintained.”
    —Robert Warshow (1917–1955)

    “The function of comedy is to dispel ... unconsciousness by turning the searchlight of the keenest moral and intellectual analysis right on to it.”
    —George Bernard Shaw (1856–1950)

    “Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
    —Frank Smith (b. 1928)
