Contributors in Biochemistry

Biochemistry

A simple carbohydrate that consists of a chain of carbon atoms, one of which is a carbonyl carbon (aldehyde or ketone), while the others bear hydroxy groups to give it the basic formula (CH 2 O) n , ...

Nomogram

Biology; Biochemistry

The presentation of three parallel linear or non-linear scales of related values aligned so that a straight line between desired points on two of the scales also crosses the third scale at the ...

Myosin

Biology; Biochemistry

A family of actin-dependent motor proteins. Classical myosins assemble to form bipolar filaments that bridge actin filaments. Motor activity causes sliding of the myosin along the filaments. Sliding ...

Hydroxyl radical footprinting

Biology; Biochemistry

The use of pulses of X-rays from a synchrotron to generate hydroxyl radicals, which will quickly react with, and thus label exposed residues of, a macromolecule as time intervals as short as 10 msec. ...

Beta (β)-pleated sheet

Biology; Biochemistry

A form of secondary structure of a protein in which the amide hydrogens of a peptide bond of one extended polypeptide sequence are shared with the carbonyl oxygens of a peptide bond on a second ...

Flux-generating step

Biology; Biochemistry

An enzymic reaction that limits the rate of subsequent steps in its metabolic pathway. In a steady state the flux of metabolites, expressed as mmol/min, is the same for all steps. The step is usually ...

Crossover experiment

Biology; Biochemistry

A method to detect the control point in a metabolic pathway by observation of the effect on metabolite levels as new steady-state levels are established after sudden creation or relieving of an ...
