- LDL is a complex composed of cholesterol, - LDL is taken into cells via LDL receptors, and, The amount of free cholesterol in the cell is, The first enzymatic step in steroid synthesis is, The enzyme that catalyzes this reaction is, The cholesterol precursor comes from cholesterol, Lipoproteins taken up from plasma are most, 1,25-dihydroxy Vitamin D3 is also derived from, Not really a vitamin as it can be synthesized, Cholesterol is lipid soluble, and mostly located, The conversion of cholesterol to steroids occurs, Now, to see if you have been paying attention, How does cholesterol get from the external, Answer Steroidogenic acute regulatory protein, The adrenal glands are located immediately, There are three classes of adrenal steroids, The first enzymatic step is the conversion of.

In the adrenal, you do NOT have to learn the, In the male, there is peripheral conversion of, The testis is organized into two main parts, - seminiferous tubules production of sperm, Leydig cells respond to luteinizing hormone (LH), Leydig cells are unusual in that they rely on de, The production of androgens from cholesterol is, Testosterone can then be converted (mostly in, - DHT (dihydrotestosterone) by 5a-reductase, or, -estradiol (E2) by cytochrome P450 aromatase, Also, know that LH stimulates Leydig cell, Ovarian steroids are secreted primarily from, The follicle is the basic functional unit of the, It is composed of an oocyte, granulosa cells, and, In the ovary, estradiol is formed from the, However, granulosa cells do not have the enzyme, Where do the androgens required for estrogen, After ovulation, the corpus luteum produces, Progesterone is also produced from theca cells, The rate of estradiol production from follicles, Estradiol production is regulated by the effects, Similarly, LH and FSH influence the expression of, Are made from cholesterol, are lipophilic can, Interact with cytoplasmic or nuclear receptors, Are slower acting and have longer half-life than, Examples cortisol, estrogen testosterone.

The mechanism by which the corpus luteum regulates steroid secretion is not completely understood. These enzymes are located in the smooth ER. This requires the loss of the 19-methyl; thus estrogens are 18-carbon (estrane) steroids.

Steroid hormones - bind to receptors within target cell and influence cell activity by acting on specific genes. Other factors which may or may not fit the definition of a hormone may also be produced locally and act locally, sometimes within the same cell. endstream
