The chemical reactions and pathways resulting in the formation of 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.

Any process that modulates the frequency, rate, or extent of metaxylem development. Metaxylem development is the process whose specific outcome is the progression of the metaxylem over time, from its formation to the mature structure. The metaxylem is the part of the primary xylem that differentiates after the protoxylem and before the secondary xylem, if any of the latter is formed.

OBSOLETE. (Was not defined before being made obsolete).

The chemical reactions and pathways resulting in the breakdown of 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.

The chemical reactions and pathways resulting in the formation of hydrocarbons that make up the cuticle, the outer layer of some animals and plants, which acts to prevent water loss.

The chemical reactions and pathways resulting in the formation of ommochromes, any of a large group of natural polycyclic pigments commonly found in the Arthropoda, particularly in the ommatidia of the compound eye.

The chemical reactions and pathways resulting in the formation of ocellus pigments, general or particular coloring matter in living organisms, found or utilized in the ocellus, a minute simple eye found in many invertebrates.

The chemical reactions and pathways resulting in the formation of eye pigments, any general or particular coloring matter in living organisms, found or utilized in the eye.

The chemical reactions and pathways resulting in the formation 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 chemical reactions and pathways resulting in the formation of pteridine, pyrazino(2,3-dipyrimidine), the parent structure of pterins and the pteroyl group.

OBSOLETE. The chemical reactions and pathways involving coenzymes, any of various nonprotein organic cofactors that are required, in addition to an enzyme and a substrate, for an enzymatic reaction to proceed.

OBSOLETE. The chemical reactions and pathways involving coenzymes and prosthetic groups.

OBSOLETE. The chemical reactions and pathways involving coenzymes that are required, in addition to an enzyme and a substrate, for an oxidoreductase reaction to proceed.

The chemical reactions and pathways resulting in the breakdown of nicotinamide riboside, the product of the formation of a glycosidic bond between ribose and nicotinamide.

The chemical reactions and pathways resulting in the formation 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.

The chemical reactions and pathways resulting in the breakdown of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions; catabolism may be of either the oxidized form, NADP, or the reduced form, NADPH.
