The chemical reactions involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus.

The process whereby a relatively unspecialized cell acquires specialized features of a mechanoreceptor, a cell specialized to transduce mechanical stimuli and relay that information centrally in the nervous system.

The chemical reactions involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones. It is a component of the plasma membrane lipid bilayer and of plasma lipoproteins and can be found in all animal tissues.

The process whereby a relatively unspecialized cell acquires specialized features of an auditory hair cell.

The chemical reactions involving ergosterol, (22E)-ergosta-5,7,22-trien-3-beta-ol, a sterol found in ergot, yeast and moulds. It is the most important of the D provitamins and is converted to vitamin D2 on irradiation with UV light.

The process whereby a relatively unspecialized hemopoietic cell acquires specialized features of a gamma-delta T cell.

The chemical reactions involving ecdysone, (22R)-2-beta,3-beta,14,22,25-pentahydroxycholest-7-en-6-one, an ecdysteroid found in insects. It is the inactive prohormone of the moulting hormone ecdysterone and may have intrinsic hormonal activity at other stages of insect development.

A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

The chemical reactions involving bile acids, any of a group of steroid carboxylic acids occurring in bile, where they are present as the sodium salts of their amides with glycine or taurine.

The series of events in which a bacterial lipoprotein stimulus is received and converted into a molecular signal. Bacterial lipoproteins are lipoproteins characterized by the presence of conserved sequence motifs called pathogen-associated molecular patterns (PAMPs).
