| amino-terminal residue | <biochemistry> The only amino acid residue in a polypeptide chain that has a free alpha-amino group, it defines the amino terminus of the polypeptide. (09 Oct 1997) |
|---|---|
| carboxyl-terminal residue | This amino acid residue defines the carboxylterminus of the polypeptide, its the only residue with a free alpha-carboxyl group. (09 Oct 1997) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| reduced eye | A simplified design of the ocular optical system, represented as having a single refracting surface and a uniform index of refraction; a model based on this concept is used in retinoscopy and ophthalmoscopy. (05 Mar 2000) |
| reduced glutathione | Glutathione acting as a hydrogen donor. (05 Mar 2000) |
| reduced haematin | 1. <biochemistry> Compounds of iron complexed in a porphyrin (tetrapyrrole) ring that differ in side chain composition. Haems are the prosthetic groups of cytochromes and are found in most oxygen carrier proteins. 2. <prefix> haem-, eaning relating to blood. Origin: G. Haima (21 Jun 2000) |
| reduced haemoglobin | The form of Hb in red blood cells after the oxygen of oxyhemoglobin is released in the tissues. (05 Mar 2000) |
| reduced interarch distance | An occluding vertical dimension which results in an excessive interocclusal distance when the mandible is in rest position, and in a reduced interridge distance when the teeth are in contact. (05 Mar 2000) |
| residue | <biochemistry> A single unit within a polymer, such as an amino acid within a polypeptide or protein. This term reflects the fact that sugars, nucleotides, and amino acids usually lose a few atoms (usually hydrogen and oxygen) when they are polymerised into a larger molecule. (10 Mar 1998) |
| centre of rotation | A point or line around which all other points in a body move. See: axis. (05 Mar 2000) |
| rotation | <dentistry> A movement in which the tooth turned along the long axis of the tooth. (08 Jan 1998) |
| rotation flap | A pedicle flap that is rotated from the donor site to an adjacent recipient area, usually as a direct flap. (05 Mar 2000) |
| rotation therapy | Teletherapy in which a desirable radiation dose distribution is achieved by rotating the patient or machine about an axis passing through the centre of the tumour. (05 Mar 2000) |
| mill residue | Wood and bark residues produced in processing logs into lumber, plywood, and paper. (05 Dec 1998) |
| short rotation energy plantation | Plantings established and managed under short-rotation intensive culture practices. (05 Dec 1998) |
