The breakdown into simpler components of formaldehyde (methanal, H2C=O), the simplest aldehyde.

The directed movement of acetylcholine into, out of, within or between cells. Acetylcholine is an acetic acid ester of the organic base choline and functions as a neurotransmitter, released at the synapses of parasympathetic nerves and at neuromuscular junctions.

The directed movement of choline into, out of, within or between cells. Choline (2-hydroxyethyltrimethylammonium) is an amino alcohol that occurs widely in living organisms as a constituent of certain types of phospholipids and in the neurotransmitter acetylcholine.

The directed movement of dopamine into, out of, within or between cells. Dopamine is a catecholamine neurotransmitter and a metabolic precursor of noradrenaline and adrenaline.

The directed movement of norepinephrine into, out of, within or between cells. Norepinephrine (3,4-dihydroxyphenyl-2-aminoethanol) is a hormone secreted by the adrenal medulla and a neurotransmitter in the sympathetic peripheral nervous system and in some tracts of the CNS. It is also the biosynthetic precursor of epinephrine.

The directed movement of biotin into, out of, within or between cells. Biotin is cis-tetrahydro-2-oxothieno(3,4-d)imidazoline-4-valeric acid; the (+) enantiomer is very widely distributed in cells and serves as a carrier in a number of enzymatic beta-carboxylation reactions.

The directed movement of carnitine into, out of, within or between cells. Carnitine is a compound that participates in the transfer of acyl groups across the inner mitochondrial membrane.

The directed movement of L-ornithine, the levorotatory isomer of 2,5-diaminopentanoic acid, into, out of, within or between cells.

The directed movement of L-proline, the levorotatory isomer of pyrrolidine-2-carboxylic acid, into, out of, within or between cells.

The directed movement of L-serine, the levorotatory isomer of 2-amino-3-hydroxypropanoic acid, into, out of, within or between cells.

The directed movement of L-aspartate, the levorotatory isomer of the anion of aspartic acid, into, out of, within or between cells.
