The scientific study of the chemistry of living matter.

Contributors in Biochemistry

Biochemistry

The fractionation of subcellular components according to their sedimentation behavior; separation into nuclei, mitochondria, lysosomes, microsomes (endoplasmic reticulum), ribosomes, cytosol, etc. by ...

Blood group substances

Biology; Biochemistry

The oligosaccharide moieties of glycoproteins that appear in many biological fluids (saliva, urine, milk) as well as on the surface of erythrocytes. These antigens, upon reaction with specific ...

Molecular clock hypothesis

Biology; Biochemistry

The proposal, so far experimentally unverified, that mutations have occurred at random and at a constant frequency in all species throughout the billions of years of biochemical evolution. Successful ...

Secondary metabolism

Biology; Biochemistry

Those metabolic pathways, other than those for energy production and for biosynthesis of nucleic acids, proteins, structural components, etc., that are unique to an organism; especially those ...

Expressed sequence tag (EST)

Biology; Biochemistry

A partial coding sequence isolated at random from a cDNA library; like a sequence-tagged site for mapping genomic DNA, used as a landmark for identification and mapping of coding sequences, for ...

Wood-Werkman reaction

Biology; Biochemistry

The proposed reaction, derived from the observed incorporation of isotopic CO 2 into succinate, by which CO 2 condenses with the 3-carbon compound pyruvate to form a 4-carbon compound, ...

Humanised antibody

Biology; Biochemistry

A chimaeric immunoglobulin of human and non-human origin. In order to minimise the possibility of the chimaera being antigenic in humans, only the hypervariable regions of a non-human monoclonal ...
