The side of the plasma membrane that faces the cytoplasm.

The chemical reactions involving any member of a large group of derivatives or analogs of porphyrin. Porphyrins consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group.

Catalysis of the reaction: a phosphatidylcholine + H2O = choline + a phosphatidate.

The formation from simpler components of any member of a large group of derivatives or analogs of porphyrin. Porphyrin consists of a ring of four pyrrole nuclei linked each to the next at their alpha positions through a methine group.

Catalysis of the reaction: H2O + acylglycerol = a fatty acid + glycerol.

Enables the directed movement of organic acids, any acidic compound containing carbon in covalent linkage, into, out of, within or between cells.

Catalysis of the reaction: organic acid(out) + Na+(out) = organic acid(in) + Na+(in).

Enables the directed movement of oxygen into, out of, within or between cells.

Catalysis of the reaction: 2-phospho-D-glycerate = phosphoenolpyruvate + H2O.

Catalysis of the reaction: ATP + 5-phospho-D-ribosylamine + glycine = ADP + phosphate + N1-(5-phospho-D-ribosyl)glycinamide.

The chemical reactions involving isoprenoid compounds, isoprene (2-methylbuta-1,3-diene) or compounds containing or derived from linked isoprene (3-methyl-2-butenylene) residues.

The chemical reactions involving terpenoids, any member of a class of compounds characterized by an isoprenoid chemical structure and including derivatives with various functional groups.

The chemical reactions involving aromatic compounds, any organic compound characterized by one or more planar rings, each of which contains conjugated double bonds and delocalized pi electrons.

A generic term for parts of cells prepared by disruptive biochemical techniques.

Combining with gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms, to initiate a change in cell activity.

Catalysis of the reaction: dopamine(out) + Na+(out) = dopamine(in) + Na+(in).
