There are three common naming conventions for specifying one of the two enantiomers (the absolute configuration) of a given chiral molecule: the R/S system is based on the geometry of the molecule; the (+)- and (−)- system (also written using the obsolete equivalents d- and l-) is based on its optical rotation properties; and the D/L system is based on the molecule's relationship to ...
Glyceraldehyde (glyceral) is a triose monosaccharide with chemical formula C 3 H 6 O 3. It is the simplest of all common aldoses. It is a sweet, colorless, crystalline solid that is an intermediate compound in carbohydrate metabolism.
Two enantiomers of a generic amino acidthat is chiral. Chirality(/kaɪˈrælɪti/) is a property of asymmetryimportant in several branches of science. The word chiralityis derived from the Greekχείρ(kheir), "hand", a familiar chiral object. An object or a system is chiralif it is distinguishable from its mirror image; that is, it cannot be ...
Omeprazole, sold under the brand names Prilosec and Losec, among others, is a medication used in the treatment of gastroesophageal reflux disease (GERD), peptic ulcer disease, and Zollinger–Ellison syndrome. [ 1 ] It is also used to prevent upper gastrointestinal bleeding in people who are at high risk. [ 1 ]
Limonene (/ ˈlɪmənˌiːn /) is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the essential oil of citrus fruit peels. [1] The (+)- isomer, occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing. [1][2] It is also used in chemical ...
Dextroamphetamine is the dextrorotatory, or 'right-handed', enantiomer and exhibits more pronounced effects on the central nervous system than levoamphetamine. Pharmaceutical dextroamphetamine sulfate is available as both a brand name and generic drug in a variety of dosage forms.
Escitalopram is the (S)- enantiomer of citalopram (which exists as a racemate), hence the name es -citalopram. [ 9 ] Escitalopram was approved for medical use in the United States in 2002. [ 9 ] Escitalopram is rarely replaced by twice the dose of citalopram; escitalopram is safer and more effective. [ 11 ]
Infobox references. Linalool (/ lɪˈnæloʊɒl, laɪ -, - loʊoʊl, - ˈluːl /) refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. [1] Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). [2][3] A ...
