They become active through hydroxylation processes first in the liver, and subsequently in the kidney.

Both Vitamin D2 and D3 are biologically inactive and are activated by two hydroxylation reactions, the first occurring in the liver to form 25(OH)D and the second occurring in the kidney to form the biologically active 1,25-dihydroxyvitamin D [1,25 (OH)2D] (see Figure 1).

Multicomponent aromatic monooxygenases contain at least two components[ 11,13] one responsible for hydroxylation (the oxygenase that binds substrate and oxygen), the other responsible for electron transfer from NAD(P)H to the oxygenase (the reductase that binds NAD(P)H).
Biopterin synthesis is a cofactor in phenylalanine and tryptophan hydroxylation, which is the rate-limiting step in the biosynthesis of dopamine and serotonin (21).
