The chemical reactions and pathways involving acetylene, a colorless, volatile, explosive gas, that occur in the absence of oxygen.

The chemical reactions and pathways resulting in the breakdown of a terminal acetylenic compound, a compound which contains a terminal alkyne moiety in which a carbon of the carbon-carbon triple bond (aka C#C) moiety is attached to a hydrogen atom.

The chemical reactions and pathways involving acetylene, formula CH2CH2, the simplest of the alkynes.

The chemical reactions and pathways resulting in the breakdown of an alkyne, any acyclic branched or unbranched hydrocarbon (compound composed only of carbon and hydrogen) having a carbon-carbon triple bond and the general formula CnH2n-2.

OBSOLETE. Any constituent part of an organelle, an organized structure of distinctive morphology and function. Includes constituent parts of the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, but excludes the plasma membrane.

The chemical reactions and pathways resulting in the breakdown of ribitol to form xylulose 5-phosphate. Ribitol is initially converted to D-ribulose, which is phosphorylated to form ribulose 5-phosphate, which is then converted into xylulose 5-phosphate.

The chemical reactions and pathways resulting in the breakdown of ribitol, a pentitol derived formally by reduction of the -CHO group of either D- or L-ribose.

Any constituent part of a virion, a complete fully infectious extracellular virus particle.

A location, relative to cellular compartments and structures, occupied by a macromolecular machine when it carries out a molecular function. There are two ways in which the gene ontology describes locations of gene products: (1) relative to cellular structures (e.g., cytoplasmic side of plasma membrane) or compartments (e.g., mitochondrion), and (2) the stable macromolecular complexes of which they are parts (e.g., the ribosome).

The chemical reactions and pathways involving methylgallate, trihydroxymethylbenzoate, the anion of methylgallic acid.

OBSOLETE. Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.

The aggregation, arrangement and bonding together of a set of components to form a motile cilium.

The assembly 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 membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

OBSOLETE. Any constituent part of the plasma membrane, the membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

OBSOLETE. Any constituent part of a microtubule organizing center, a region in a eukaryotic cell, such as a centrosome or basal body, from which microtubules grow.

OBSOLETE. Any constituent part of the nucleoplasm, that part of the nuclear content other than the chromosomes or the nucleolus.

The chemical reactions and pathways resulting in the breakdown of proline into other compounds, including 2-oxoglutarate.

The chemical reactions and pathways resulting in the breakdown of proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.

OBSOLETE. Any constituent part of a nucleolus, a small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis.
