It is the family of 50 powerful enzymes known as Cytochrome P450 that is responsible for converting cholesterol into the 'master' steroid hormone, pregnenolone. I choose to call pregnenolone a 'master hormone' because it is converted into numerous other vital hormones.
Mayweather has been arrested several times since 2002 in battery and violence cases in Las Vegas and in his hometown of Grand Rapids, Mich. He was convicted in 2002 of misdemeanor battery stemming from a fight with two women at a Las Vegas nightclub.
But before the biggest fight of his career another, darker aspect of his life outside the ring is resurfacing. Mayweather has a long history of domestic violence. Since 2002 Mayweather has been accused of violence against women with alarming frequency. He pleaded guilty in two of those incidents, and in another he was convicted only to have the charges dismissed four years later.
