Примери за amine

• It was early recognized that the alkaloids were complex amines or ammonia derivatives. 

• Strychnine has been found to be a tertiary amine. 

• In fact, there are specific postnatal critical periods and developmental sequences for the appearance of the biogenic amines dopamine and noradrenaline.

• The active compounds share a common structural motif : a protonatable amine moiety separated from an ionized sulfonate moiety by 2 or 3 methylene groups.

• In the other isomers, where the two groups are linked together, the carbonyl group attracts the electrons, which destabilizes the protonated amine.

• Biogenic amines were selected on the basis of their effects during frequency of movement assays.

• Table 2 depicts the data for the biogenic amines and their metabolites under basal and separation conditions.

• The major inactivation of biogenic amines is performed by monoamine oxidase, an enzyme located solely in mitochondria.

• Trace amines are endogenous amine compounds structurally related to the classical monoamine neurotransmitters.

• The effects of the fetal environment on the development of biogenic amine systems have received less attention than genetic or postnatal environmental factors.

• The primary aim was to determine whether prenatal stress persistently alters the activity of brain biogenic amine systems.

• Clinical treatment was instituted initially, using high doses of diuretics, peripheral vasopressor and vasodilator amines.

• But this problem would not hamper data collection on hydrogen bonds to amines, since amino protons exchange readily with solvent.

• A longitudinal study of the effects of different rearing environments on cerebrospinal fluid norepinephrine and biogenic amine metabolites in rhesus monkeys.

• Consequently, the same isomers were studied as before, first protonated on the acid group, then on the amine group.

• Red regions are around the carboxyl oxygens, and blue regions are around hydrogens and the amine group.

• Biotinylated dextran amine as an anterograde tracer for single- and double-label studies.
