| ferredoxin-NADP reductase | <enzyme> An enzyme that catalyses the oxidation and reduction of ferredoxin or adrenodoxin in the presence of NADP. Chemical name: Ferredoxin:NADP+ oxidoreductase Registry number: EC 1.18.1.2 (12 Dec 1998) |
| ferredoxin-thioredoxin reductase | <enzyme> Found in chloroplasts Registry number: EC 1.18.- (26 Jun 1999) |
| formaldehyde | <chemical> Commonly used fixative and antibacterial agent. As a fixative it is cheap and tends to cause less denaturation of proteins than does glutaraldehyde, particularly if used in a well buffered solution (buffered formalin, formal saline). Old formaldehyde solutions usually contain cross linking contaminants and it is therefore often preferable to used a formaldehyde generating agent such as paraformaldehyde. Formalin fumes, particularly in conjunction with hydrochloric acid vapour, are potently carcinogenic. (20 Jun 2000) |
| formaldehyde dismutase | <enzyme> Contains noncovalently bound nad(h); forms equimolar amounts of corresponding alcohols and acids from various aldehydes Registry number: EC 1.1.1.- (26 Jun 1999) |
| formaldehyde fixative | A widely used fixing agent for pathologic histology; the commercial solution is 37-40% formaldehyde and is known as 100% formalin or formol; a common impurity is formic acid, which must be neutralised or the fixative made in buffer solution; tissues fixed may have a pigment artifact precipitated.
