Biochemistry

A graphical method for determination of enzyme-inhibitor dissociation constants for non-competitive inhibitors, especially those that bind very tightly. Where I is the total inhibitor concentration, ...

Dixon plot

Biology; Biochemistry

A graphical method for determination of the type of enzyme inhibition and the dissociation constant (K i ) for an enzyme-inhibitor complex. The effect on the enzymic rate (v) is determined at two or ...

complexity

Biology; Biochemistry

In nucleic acid chemistry, a measure of the unique sequences in a DNA preparation; it increases with chain length and decreases with the extent to which the sequences are repetitive; evaluated as the ...

fluorescence-activated cell sorting (FACS)

Biology; Biochemistry

A technique for separation of cells according to their fluorescence after attachment of a fluorophore to specific cells, e.g. with a fluorescent antibody. Droplets that contain no more than one cell ...

Gortner and Grendel model

Biology; Biochemistry

A model in which erythrocyte membranes comprise only phosphoacylglycerols, i.e. no protein or sterol component is envisaged; the model presents a bilayer in which each leaflet is composed of lipids ...

apoptosis

Biology; Biochemistry

A morphologically characterized process of programmed cell-death, initiated by various physiological or pathological causes (e.g. cell turnover, hormone-induced atrophy, cell-mediated immune ...

glucose effect

Biology; Biochemistry

The repression of some bacterial enzymes by the presence of glucose in the growth medium. Depression of cyclic AMP levels due to the availability of glucose is mediated by inhibition of adenylate ...
