| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
|---|---|
| bitter peptides | Peptides that have a bitter taste and may spoil certain foods; often contain high proportions of leucyl, valyl, and aromatic amino acid residues. (05 Mar 2000) |
| peptides | Any member of a class of compounds of low molecular weight which yield two or more amino acids on hydrolysis. Formed by loss of water from the nh2 and cooh groups of adjacent amino acids, they are known as di-, tri-, tetra- (etc.) peptides, depending on the number of amino acids in the molecule. Peptides form the constituent parts of proteins. (12 Dec 1998) |
| signal peptides | Additional polypeptide sequence of 25 to 30 residues at the amino-terminal or carboxy-terminal end of proteins. The signal sequence signals the cellular fate or destination of a newly synthesised protein directing it to its ultimate destination in the cell. These leaders are recognised by the signal recognition particle and bound by specific receptor sites on the outer surface of the endoplasmic reticulum. They are then transported into the cisterna of the endoplasmic reticulum and from there directed to their ultimate destination in the cell. In prokaryotes, the signal peptides attach to the plasma membrane. These signal sequences are ultimately removed by specific peptidases. (12 Dec 1998) |
| opioid peptides | The endogenous peptides with opiate-like activity. The three major classes currently recognised are the enkephalins, the dynorphins, and the endorphins. Each of these families derives from different precursors, proenkephalin, prodynorphin, and pro-opiomelanocortin, respectively. There are also at least three classes of opioid receptors, but the peptide families do not map to the receptors in a simple way. (12 Dec 1998) |
| Buck's extension | Apparatus for applying longitudinal skin traction on the leg through contact between the skin and adhesive tape; friction between the tape and skin permits application of force, which is applied through a cord over a pulley, suspending a weight; elevation of the foot of the bed allows the body to act as a counterweight. Synonym: Buck's traction. (05 Mar 2000) |
| paraplegia in extension | Paralysis of the legs, maintained in an extended position by hypertonic extensor muscles. (05 Mar 2000) |
| ridge extension | An intraoral surgical operation for deepening the labial, buccal, and/or lingual sulci; it is performed to increase the intraoral height of the alveolar ridge in order to assist denture retention. (05 Mar 2000) |
| crossed extension reflex | Extension of the contralateral hind limb when the paw of an animal is painfully stimulated or the central cut end of an afferent nerve, e.g., the peroneal, is stimulated; sometimes occurs in humans upon tapping the skin. (05 Mar 2000) |
| primer extension | A technique for determining the 5'-untranslated region of a specific mRNA molecule. Uses an oligonucleotide complementary to the known RNA sequence as a primer for cDNA synthesis via reverse transcriptase. (05 Mar 2000) |
| skeletal extension | Traction pull on a bone structure mediated through pin or wire inserted into the bone to reduce a fracture of long bones. Synonym: skeletal extension. (05 Mar 2000) |
| nail extension | An obsolete method of extension, by a weight on a nail or pin in the distal fragment of a fracture. (05 Mar 2000) |
| extension | 1. <orthopaedics> The movement by which the two elements of any jointed part are drawn away from each other. 2. <anatomy> A movement which brings the members of a limb into or toward a straight relation. Origin: L. Extensio (18 Nov 1997) |
| extension bridge | A fixed partial bridge denture in which the pontic is retained only on one side by an abutment tooth. Synonym: extension bridge. (05 Mar 2000) |
| extension form | The extension of the cavity preparation outline form to include areas of incipient carious lesions; this extension provides a dental restoration with margins that are self-cleansing or easily cleaned. (05 Mar 2000) |
