Biochemistry

In β-oxidation, cleavage of the bond between the β- and γ-carbons by coenzyme A to form acetyl-coenzyme A from carbons α and β and a coenzyme A thioester from the alkyl-carbonyl moiety, i.e. carbons ...

Human artificial chromosome (HAC)

Biology; Biochemistry

An artificial assembly of chromosome features, telomere, centromere, etc., that is used to test the minimum features required for replication in transfected cells. The mammalian artificial chromosome ...

Nitrogen fixation

Biology; Biochemistry

The reduction of molecular nitrogen to ammonia and nitrogen-containing metabolites that is carried out synthetically, or naturally by blue-green algae or bacteria, e.g. Rhizobium species that inhabit ...

Anaplerotic pathway

Biology; Biochemistry

Metabolic reactions that replenish the pools of intermediates of the tricarboxylic acid cycle. These pools may become depleted, as they also serve as precursors for amino acid synthesis, ...

Ascus

Biology; Biochemistry

A spore-like form through which yeast cells pass during their life cycle; an outer wall surrounds a diploid cell that undergoes meiosis to form four haploid cells (ascospores) which eventually ...

Chloride shift

Biology; Biochemistry

The movement of chloride ions into erythrocytes as bicarbonate exits, due to the generation by carbonic anhydrase of bicarbonate from carbonic acid inside the cells as they pass through peripheral ...

Antigen presentation

Biology; Biochemistry

The appearance on the surface of a cell of a foreign protein, e.g. one that arises from viral infection, in a complex with a class I major histocompatibility complex protein. It is this complex that ...
