Contributors in Biochemistry

Biochemistry

In kinetics and spectroscopy, the return to equilibrium of a macromolecule after a very brief perturbation of the environment, e.g. recovery of a protein from a sudden burst of energy that allows a ...

Peptidoglycan

Biology; Biochemistry

A polymer of bacterial cell walls that exhibits considerable species variation in structure. It is generally composed of a heterodisaccharide attached to a peptide; the carbohydrate moieties of ...

Opsonin

Biology; Biochemistry

An agent of the blood, especially of the complement system, which can react with by-products of cell damage and with foreign substances and particles, such as bacteria. Opsonization allows leukocytes ...

Beer-Lambert equation

Biology; Biochemistry

A=ε c ·l; a quantitative definition of the dependence of the absorbance of monochromatic light, A, on the molar absorption coefficient, ε, the concentration of the chromophore, c, and the length ...

Minimal molecular mass

Biology; Biochemistry

A value for the molecular mass of a macromolecule calculated from its content of a metal ion, end group or other feature present in an unknown stoichiometric ratio, e.g. the minimal molecular mass of ...

Bile acid

Biology; Biochemistry

One of the products of cholesterol hydroxylation and side-chain oxidation to the level of a carboxylic acid. The carboxylate is often conjugated through an amide bond to a glycine or a cysteic acid. ...

Hydrazinolysis

Biology; Biochemistry

In determination of the C-terminal amino acid of a protein, cleavage of a peptide bond by insertion across it of the elements of hydrazine; in the Maxam-Gilbert method for sequencing polynucleotides, ...
