Add to ORKGMore than two centuries have elapsed since the first isolation of cholesterol, yet its structure was elucidated only twenty-two years ago and its total synthesis was achieved in 1951. The first steroid hormone to be isolated in pure state was estrone in 1929. Within a short period of time the various sex hormones, estrogens, androgens and progestins were isolated, characterized and synthesized. The compounds elaborated by the adrenal cortex were the last type of steroid hormones to be investigated. Experiments initiated in 1935 led to the isolation and characterization of twenty-eight crystalline steroids, six of which exhibit activity in prolonging the life of adrenalectomized animals
