CHEMISTRY GLOSSARY
psychoactive drug → psihoaktivna droga
Psychoactive drugs are natural (mescaline) or synthetic substances (LSD) which take effect on central nervous system causing euphoria, and by lengthened use they also cause addiction, gradually destroying the nervous system.
refractory metal → vatrostalni metal
Refractory metal is a metal having an extremely high melting point, for example tungsten, molybdenum, niobium, tantalum, and rhenium
resonant frequency → rezonantna frekvencija
All vibrating systems have one or more resonant frequencies, which depend on system characteristics. If an external force is applied on the system at that frequency, the vibrations will be much greater than at slight different frequencies.
glycosidic bond → glikozidna veza
Glycosidic bond ia a bond between the glycosyl group, the structure obtained by removing the hydroxy group from the hemiacetal function of a monosaccharide, and the -OR group (which itself may be derived from a saccharide and chalcogen replacements thereof (RS–, RSe–). The terms N-glycosides and C-glycosides are misnomers and should not be used. The glycosidic bond can be α or β in orientation, depending on whether the anomeric hydroxyl group was α or β before the glycosidic bond was formed and on the specificity of the enzymatic reaction catalyzing their formation. Once the glycosidic bond is formed, the anomeric configuration of the ring is locked as either α or β. Specific glycosidic bonds therefore may be designated α(1→4), β(1→4), α(1→6), and so on. Cellulose is formed of glucose molecules linked by β(1→4)-glycosidic bonds, whereas starch is composed of α(1→4)-glycosidic bonds.
half-wave potential → poluvalni potencijal
Half-wave potential (E1/2) is a potential at which polarographic wave current is equal to one half of diffusion current (id). In a given supporting electrolyte, the half-wave potential is unique for each element and its different valence states and chemical forms. Observation of a current peak at a specific half-wave potential therefore identifies the chemical species producing the current.
secondary alcohol → sekundarni alkohol
Secondary alcohol is one in which the hydroxyl group (-OH) is attached to a secondary carbon atom (i.e. a carbon atom which has one hydrogen atom attached to it).
tertiary alcohol → tercijarni alkohol
Tertiary alcohols are aliphatic alcohols in which the hydroxyl group (-OH) is attached to a tertiary carbon atom.
