Neutral
Definition:
(a.) Not engaged on either side; not taking part with or assisting either of two or more contending parties; neuter; indifferent.
(a.) Neither good nor bad; of medium quality; middling; not decided or pronounced.
(a.) Neuter. See Neuter, a., 3.
(a.) Having neither acid nor basic properties; unable to turn red litmus blue or blue litmus red; -- said of certain salts or other compounds. Contrasted with acid, and alkaline.
(n.) A person or a nation that takes no part in a contest between others; one who is neutral.
Example Sentences:
(1) F(420) is photolabile aerobically in neutral and basic solutions, whereas the acid-stable chromophore is not photolabile under these conditions.
(2) Further analysis with two other synthetic peptides (212Cys to 222Glu and Cys X 221Ile to 236Glu) indicated that the dodecapeptide Ile-Glu-Phe-Gln-Lys-Asn-Asn-Arg-Leu-Leu-Glu mimicked either the whole or a major part of the neutralization epitope.
(3) In addition to esophageal manometry, we also performed acid-clearance studies and examined salivary output, acid-neutralizing capacity, and bicarbonate concentration.
(4) The presence of the expected C19 neutral and C18 phenolic steroids was confirmed.
(5) The free nucleoside IV was obtained by removal of blocking groups by sodium methoxide catalyzed deacylation, deionization under reducing atmosphere, and chromatography on neutral alumina.
(6) The spikes likely correspond to VP3, a hemagglutinin, while the rest of the mass density in the outer shell represents 780 molecules of VP7, a neutralization antigen.
(7) Poly (8NH2G) does not interact with poly(C) in neutral solution because of the high stability of the hemiprotonated G-G self-structure.
(8) Interaction of viable macrophages with cationic particles at 37 degrees C resulted in their "internalization" within vesicles and coated pits and a closer apposition between many segments of plasmalemma than with neutral or anionic substances.
(9) Most of the antibodies had some degree of complement-independent neutralizing capacity, but in common was a large neutralization-resistant fraction of virus (range 13 to 78%).
(10) Neutral sucrose density sedimentation patterns indicate that neutron-induced double strand-breaks sometimes occur in clusters of more than 100 in the same phage and that the effeciency with which double strand-breaks form is about 50 times that of gamma-induced double strand-breaks.
