Different chemical classes of hormones are made from different substrates and are soluble in different solvents. Steroid hormones are synthesized from cholesterol and include: testosterone, aldosterone, cortisol, estradiol and progesterone. They are soluble in lipids (fat-soluble) and can therefore be administered orally.
Other kinds of hormones, eg: tyrosine-based hormones and protein hormones, are made from different substances (eg: amino acids) and may be water soluble and therefore cannot be administered orally.
They simply pass through the cell membrane of the targeted cell. This is possible because steroid hormones are fat-soluble, and the fluid mosaic ( phospholipid bilayer ) prevents fat-insoluble molecules from diffusing into the cell.

Cartman pretends to be mentally handicapped in episode 2 of season 8, "Up the Down Steroid".
yes he did. they found prescription pills, some type of steroid, and cocaine residue. the story is he went to jail but got bailed out by Matt.
The difference between amine and peptide hormones are:Amine hormones are from amino acids. Peptide Hormones are peptide bonds between multiple amino acids.
Steroid Hormones
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
Peptide based hormones exert their effects on a cell by way of second messengers (cAMP or PIP) pathways. Steroid based hormones exert their effects on a target cell via direct gene activation.
No lysosomes do not make steroid hormones. Lysosomes are organelles that are found in the cells of animals. Steroid hormones are made by estrogen and testosterone.
Steroid Hormones only enter the bloodstream by diffusion. If you are a student taking anatomy/phyiso 2 and refering to this question: All steroid hormones are derived from (cholesterol). Which steroid hormone is produced is determined by the (enzymes) present in the cell. The common precursor molecule for all steroid hormones is (pregnenolone). Steroid hormones enter the blood stream by (diffusion) and (do) require a carrier. The rate of secretion of steroid hormones is (slower) then catecholemines because steroid hormones are not (stored). Hope that helps-
Some of the steroid hormones are produced by the adrenal cortex. Steroid hormones are soluble in lipids. Steroid hormones travel in the blood attached to the carrier proteins.

Bile acids - from liver cells. Steroid hormones _ from the adrenal glands.
