| biocytin | <protein> The amino acid residue formed when biotin links covalently via anamide linkage to a Lys residue. (09 Oct 1997) |
|---|---|
| biocytinase | <enzyme> An enzyme which converts biocytin into biotin (one of the B vitamins) and lysine (an amino acid). (09 Oct 1997) |
| biodegradable | A substance that can be chemically degraded via natural effectors such as soil bacteria, weather, plants or animals. (27 Sep 1997) |
| biodegradation | The series of processes by which living systems render chemicals less noxious to the environment. (18 Nov 1997) |
| biodiesel | A biofuel produced through transesterification, a process in which organically- derived oils are combined with alcohol (ethanol or methanol) in the presence of a catalyst to form ethyl or methyl ester. The biomass- derived ethyl or methyl esters can be blended with conventional diesel fuel or used as a neat fuel (100% biodiesel). Biodiesel can be made from soybean or rapeseed oils, animal fats, waste vegetable oils, or microalgae oils. (05 Dec 1998) |
| biodiversity | The existence of a wide range of different types of organisms in a givenplace at a given time. (09 Oct 1997) |
| biodynamic | Relating to biodynamics. (05 Mar 2000) |
| biodynamics | <biology> The doctrine of vital forces or energy. Origin: Gr. Life + E. Dynamics. Source: Websters Dictionary (01 Mar 1998) |
| bioecology | <study> The scientific study of the relationship of organisms to each other and to their environment. (09 Oct 1997) |
| bioelectric energy sources | Implantable devices which convert biological energy (chemical energy of the metabolism of continuously regenerating body fluids or mechanical energy of periodic movements) to electrical energy. The sources include biogalvanic cells, biofuel cells, and ionic concentration cells. (12 Dec 1998) |
| bioelectric potential | Electrical potential's occurring in living organisms. (05 Mar 2000) |
| bioelectricity | The naturally-occurring electrical currents which flow within nerves and muscles. (09 Oct 1997) |
| bioelectronics | The study of how electrons are transferred between molecules during biological regulation or biological defense. The movement of electrons is fairly important to the study of metabolism mechanisms. (09 Oct 1997) |
| bioelement | An element required by a living organism. (05 Mar 2000) |
| bioenergetics | <study> A scientific field that deals with the application of thermodynamicprinciples to organisms and biological systems. (09 Oct 1997) |
