The formation from simpler components of tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.

The breakdown into simpler components of androgens, C19 steroid hormones that can stimulate the development of male sexual characteristics.

The breakdown into simpler components of estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants.

The breakdown into simpler components of glucocorticoids, hormonal C21 corticosteroids synthesized from cholesterol.

The chemical reactions involving sesquiterpenoid compounds, terpenoids with three isoprene units.

The chemical reactions involving juvenile hormones, the three sesquiterpenoid derivatives that function to maintain the larval state of insects at molting and that may be required for other processes, e.g. oogenesis.

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 X-ray radiation. An X-ray is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz).

The chemical reactions involving wax, a compound containing C16 and C18 fatty acids.

reduced nicotinamide adenine dinucleotide phosphate regeneration

reduced nicotinamide adenine dinucleotide phosphate biosynthesis

The formation from simpler components of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; biosynthesis may be of either the oxidized form, NADP, or the reduced form, NADPH.
