The scientific study of the chemistry of living matter.

Contributors in Biochemistry

Biochemistry

The internal movement possible in some proteins, in which domains show little internal movement but move relative to each other by flexion at the hinges that connect them, e.g. the wagging movement ...

Autophagocytosis

Biology; Biochemistry

The response of a cell to stress in which it forms an autophagosome, an organelle that contains parts of the cell's own cytoplasm. Later this will fuse with a lysosome to form an autolysosome; all ...

Carbon cycle

Biology; Biochemistry

The movement of carbon atoms through different chemical forms and locations, from dissolved CO 2 in equilibrium with atmospheric CO 2 through plant carbohydrate, fats and proteins of plants and ...

Genomic tag model

Biology; Biochemistry

The hypothesis that a tRNA-like loop (the tag) of the genomic RNA of some viruses that functions in copying a strand of RNA into a complementary RNA or DNA strand is a relic of the part of the RNA ...

Vitamin

Biology; Biochemistry

A compound required in the diet in minute amounts; fat-soluble if soluble in organic solvents (vitamins A, D and E); water-soluble if soluble in aqueous solutions (ascorbic acid, biotin, cobalamin, ...

Regulatory subunit

Biology; Biochemistry

A part of a multimeric enzyme; a protein that binds to and inhibits the catalytic subunit unless it is bound to a regulating molecule; e.g. in the case of cyclic AMP-dependent protein kinase, the ...

Microcluster

Biology; Biochemistry

An aggregate of several (2‒10) membrane receptors that forms in response to cell stimulation; such an aggregate is a transitory state between the receptors being dispersed in the membrane and their ...
