Biochemistry

The scientific study of the chemistry of living matter.

Contributors in Biochemistry

Biochemistry

The homing of cells or viruses to specific tissues or organs, which is facilitated by organ-selective address molecules on the target tissue surface that tightly bind to cell-specific markers on the ...

homology

Biology; Biochemistry

The similarity in base sequences of genes or amino acid sequences of proteins that denotes a common evolutionary origin; also the similarity of structure or function of proteins that is due to a ...

transfer RNA (tRNA)

Biology; Biochemistry

The RNA that serves in protein synthesis as an interface between mRNA and amino acids. It carries an anticodon sequence that pairs bases with a codon of mRNA, and it binds an amino acid at its 3'-end ...

pyrophosphorylation

Biology; Biochemistry

A post-transcriptional modification of a protein, e.g. the transfer of a phosphate group from pentaphosphatyl-inositol-pyrophosphate to a phopsphoprotein, resulting in a pyrophosphoryl protein and a ...

mitochondrion

Biology; Biochemistry

An organelle of eukaryotic cells that is the site of oxidative phosphorylation, the tricarboxylic acid cycle, β-oxidation, etc., and is composed of a relatively permeable outer membrane and a deeply ...

electron sink

Biology; Biochemistry

In discussions of enzyme mechanisms, a group that can pull electrons from a reactive center and thus stabilize an electron-deficient intermediate or transition state, e.g. pyridoxal phosphate ...

RNA interference (RNAi)

Biology; Biochemistry

The phenomenon of gene silencing effected by the interaction of a double-stranded RNA, approx. 22 bp long, with the cognate genomic DNA sequence. The RNA-DNA complex is subject to hydrolysis by a ...
