All terms in NCIT

Label	Id	Description
Mass-to-Charge Ratio	NCIT_C48049	[The abbreviation m/z is used to denote the dimensionless quantity formed by dividing the mass number of an ion by its charge number. It has long been called the mass-to-charge ratio although m is not the ionic mass nor is z a multiple or the elementary (electronic) charge e. (from IUPAC Compendium)]
Precursor	NCIT_C48044	[A substance from which another substance is formed.]
Precision	NCIT_C48045	[A quantitative representation of the degree of accuracy necessary for or associated with a particular action.]
Pair	NCIT_C48046	[A set of two similar things considered as a unit.]
Byte	NCIT_C48047	[A sequence of 8 bits processed as a single unit of information.]
Matrix-Assisted Laser Desorption Ionization Mass Spectrometry	NCIT_C48040	[A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample- matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis. (CHI)]
Mass Spectrometry	NCIT_C17156	[An analytical technique wherein ions are separated according to their ratio of charge to mass. From the mass spectrum produced, the atomic weight of the particle can be deduced.]
Plate	NCIT_C48041	[A sheet of metal or wood or glass or plastic.]
Dead Volume	NCIT_C48042	[Any volume which a component introduces to a system that is not cleanly swept and relies on diffusion to clear the space; a dead-end passageway or cavity that can retain materials to contaminate subsequent samples or flow media.]
Triampyzine	NCIT_C87650
Protein Helix	NCIT_C48043	[A protein secondary structure motif. Amino acids are arranged in a right-handed rod like structure stabilized by hydrogen bonds between the C=O and the N-H groups of the main chain. Types include:alpha-helix, 3.10 helix and pi-helix.]
Secondary Protein Structure	NCIT_C13302	[The specific 3-dimensional folded protein structure that is determined by the hydrogen bonds formed between amino acids in the polypeptide chain.]
N-Acetylcysteine Amide	NCIT_C87651
Piperaquine	NCIT_C87634
m-Cresyl Acetate	NCIT_C87635	[The acetic acid ester of metacresol, an agent with antiseptic and analgesic properties. m-Cresyl acetate is used in an otic solution to treat bacterial and fungal infections of the outer ear, and in endodontic procedures.]
Telavancin Hydrochloride	NCIT_C87636	[The hydrochloride salt form of telavancin, a lipoglycopeptide and a semisynthetic derivative of vancomycin with antibacterial activity against gram-positive bacteria. Like vancomycin, telavancin binds tightly to the D-alanyl-D-alanine residue of cell wall precursors, thereby interfering with bacterial cell wall synthesis. In addition, the lipophilic moiety of telavancin may interact with the lipid bilayer in the bacterial cell membrane, thereby compromising the integrity of cell membrane and causing cell membrane depolarization. This novel mechanism of action may contribute to telavancin's rapid bactericidal activity and its improved activity over vancomycin against some antibiotic resistance gram-positive bacteria.]
Glycopeptide Antibiotic	NCIT_C61101	[One of a class of antibiotics originally isolated from plant and soil bacteria with structures containing either a glycosylated cyclic or polycyclic nonribosomal peptide. These antibiotics inhibit the cell wall structure of susceptible organisms (principally Gram-positive cocci) by inhibiting peptidoglycan synthesis. First-generation glycopeptide antibiotics include vancomycin, teicoplanin, and ramoplanin; second-generation semi-synthetic glycopeptide antibiotics include oritavancin, dalbavancin, and telavancin.]
Etipirium	NCIT_C87637
Nebidrazine	NCIT_C87630
Quinuclium	NCIT_C87631
