Catalysis of the reaction: CMP-N-acetylneuraminate + beta-D-galactosyl-1,3-N-acetyl-alpha-D-galactosaminyl-R = CMP + alpha-N-acetylneuraminyl-2,3-beta-D-galactosyl-1,3-N-acetyl-alpha-D-galactosaminyl-R.

Catalysis of the reaction: homocysteine + betaine = L-methionine + dimethylglycine.

The chemical reactions involving L-phenylalanine, the levorotatory isomer of 2-amino-3-phenylpropanoic acid.

The breakdown into simpler components of phenylalanine, 2-amino-3-phenylpropanoic acid.

The chemical reactions involving melanins, pigments largely of animal origin. High molecular weight polymers of indole quinone, they are irregular polymeric structures and are divided into three groups: allomelanins in the plant kingdom and eumelanins and phaeomelanins in the animal kingdom.

The formation of melanin from simpler components, including tyrosine.

The chemical reactions involving any of a group of physiologically important biogenic amines that possess a catechol (3,4-dihydroxyphenyl) nucleus and are derivatives of 3,4-dihydroxyphenylethylamine.

A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

A series of molecular signals that leads to the upregulation of calcium-dependent phospholipase A2 activity in response to the signal.
