Pterins, as a group, are
compounds related to
pterin with
additional substituents.
Pterin itself is of no
biological significance.
Pterins were first...

tetrahydrobiopterin (BH4) is the
endogenous cofactor for AAAH enzymes. As with
pterins in general,
biopterins exhibit tautomerism. In

generating this
color are
pterins and carotenoids.
These two
pigments are the most
easily seen
through the anole's eyes.

Pterins have a role in
