molecular function
    GO:0004032    alditol:NADP+ 1-oxidoreductase activity    Catalysis of the reaction: an alditol + NADP+ = an aldose + NADPH + H+.
    GO:0004033    aldo-keto reductase (NADP) activity    Catalysis of the reaction: an alcohol + NADP+ = an aldehyde or a ketone + NADPH + H+.
    GO:0047042    androsterone dehydrogenase (B-specific) activity    Catalysis of the reaction: NAD(P)+ + androsterone = NAD(P)H + H+ + 5-alpha-androstane-3,17-dione. The reaction is B-specific (i.e. the pro-S hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD(P)+.
    GO:0047023    androsterone dehydrogenase activity    Catalysis of the reaction: NAD(P)+ + androsterone = NAD(P)H + H+ + 5-alpha-androstane-3,17-dione.
    GO:0032052    bile acid binding    Interacting selectively and non-covalently with bile acids, any of a group of steroid carboxylic acids occurring in bile.
    GO:0031406    carboxylic acid binding    Interacting selectively and non-covalently with a carboxylic acid, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-).
    GO:0047086    ketosteroid monooxygenase activity    Catalysis of the reaction: O2 + NADPH + progesterone = H2O + NADP+ + testosterone acetate.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016655    oxidoreductase activity, acting on NAD(P)H, quinone or similar compound as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a quinone or a similar acceptor molecule.
    GO:0018636    phenanthrene 9,10-monooxygenase activity    Catalysis of the reaction: phenanthrene + O2 + NADH + H+ = H2O + NAD+ + phenanthrene-9,10-oxide.
    GO:0033764    steroid dehydrogenase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor    Catalysis of an oxidation-reduction (redox) reaction in which a CH-OH group acts as a hydrogen or electron donor and reduces NAD+ or NADP, and in which one substrate is a sterol derivative.
    GO:0047115    trans-1,2-dihydrobenzene-1,2-diol dehydrogenase activity    Catalysis of the reaction: NADP+ + trans-1,2-dihydrobenzene-1,2-diol = NADPH + catechol.
biological process
    GO:0006629    lipid metabolic process    The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0006694    steroid biosynthetic process    The chemical reactions and pathways resulting in the formation of steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus; includes de novo formation and steroid interconversion by modification.
    GO:0008202    steroid metabolic process    The chemical reactions and pathways involving steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
