A one-carbon metabolic process in which acetyl-CoA is produced from formaldehyde and carbon dioxide.

The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.

OBSOLETE. Any constituent part of the nuclear membrane, the envelope that surrounds the nucleus of eukaryotic cells.

The chemical reactions and pathways involving hexachlorocyclohexane, a cyclohexane derivative with 6 chlorine atoms attached to the hexane ring. Hexachlorocyclohexane consists of a mixture of 8 different isomers and was used a commercial insecticide. It is persistent in the environment, causing serious soil pollution.

The chemical reactions and pathways involving chlorinated hydrocarbons, compounds derived from hydrocarbons by replacing one or more hydrogen atoms with chlorine atoms.

OBSOLETE. Any constituent part of a nuclear chromosome, a chromosome that encodes the nuclear genome and is found in the nucleus of a eukaryotic cell during the cell cycle phases when the nucleus is intact.

The chemical reactions and pathways resulting in the conversion of n-octane to octanoyl-CoA.

The chemical reactions and pathways involving n-octane, the 8 carbon straight chain alkane used in organic syntheses, calibrations, and azeotropic distillations. It is a common component of gasoline and other petroleum products and the engine fuel antiknocking properties of an isomer of n-octane are used as a comparative standard in the Octane Rating System.

OBSOLETE. Any constituent part of a mitochondrial membrane, either of the lipid bilayers that surround the mitochondrion and form the mitochondrial envelope.

OBSOLETE. Any constituent part of a synapse, the junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell.

OBSOLETE. Any constituent part of a cell septum, a structure composed of peptidoglycan and often chitin in addition to other materials. It usually forms perpendicular to the long axis of a cell or hypha and grows centripetally from the cell wall to the center of the cell and often functions in the compartmentalization of a cell into two daughter cells.

OBSOLETE. Any constituent part of an axoneme, the bundle of microtubules and associated proteins that forms the core of cilia (also called flagella) in eukaryotic cells and is responsible for their movements.

OBSOLETE. Any constituent part of the cell cortex, the region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

OBSOLETE. Any constituent part of a contractile fiber, a fiber composed of actin, myosin, and associated proteins, found in cells of smooth or striated muscle.

OBSOLETE. Any constituent part of an endosome, a membrane-bounded organelle to which materials ingested by endocytosis are delivered.

OBSOLETE. Any constituent part of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

OBSOLETE. Any constituent part of a pilus, a proteinaceous hair-like appendage on the surface of bacteria ranging from 2-8 nm in diameter.

OBSOLETE. Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

OBSOLETE. Any constituent part of cytosol, that part of the cytoplasm that does not contain membranous or particulate subcellular components.
