Biochemistry

Lipid peroxidation

Biology; Biochemistry

The oxidation of polyunsaturated fatty acid side chains, initiated by a free radical such as the hydroxyl radical (OH ), to form a relatively stable carbon free radical, which reacts further with ...

The translation product of an oncogene; a regulator of cellular processes, which if the gene is mutated, results in uncontrolled growth (cancer). Oncoproteins may be embedded in the plasma membrane ...

Hydropathy plot

Biology; Biochemistry

A graph that shows regions of hydrophobicity or polarity of a protein; a line graph that displays the hydropathy index against the position of each residue of the protein. Each residue is averaged ...

Antioxidant

Biology; Biochemistry

A scavenger of reactive oxygen free radical species (OH Â· , O 2 -Â· , etc.) and other oxidising compounds; of particular importance are those that act as antioxidants in vivo, e.g. ascorbate, ...

C-terminal

Biology; Biochemistry

In a polypeptide sequence, that unique residue which is connected to the linear sequence by its amino group, leaving it with a free carboxy group. In practice, the carboxy group of a C-terminal ...

Paralogous

Biology; Biochemistry

Descriptive of homologous genes that have duplicated and evolved divergently, e.g. those encoding trypsin, chymotrypsin, elastase and thrombin, which are all serine proteinases and occur together ...

Replication fork

Biology; Biochemistry

The site where the two polynucleotides of a parent DNA separate during replication. The daughter strands are attached to the two separated polynucleotides that trail away from the fork as it advances ...
