dextrorotatory

Thân thiện

A scientist observes a dextrorotatory crystal under polarized light.

Definition

1. Adjective:
   • Rotating to the right: In chemistry and physics, "dextrorotatory" describes a substance that rotates the plane of polarized light to the right (clockwise) when viewed in the direction of the light source. It is often abbreviated as d- or (+).

Usage

• The term is used almost exclusively in scientific contexts, particularly in optics, chemistry, and biochemistry, to describe the optical activity of chiral molecules like sugars and amino acids.
• It is the opposite of "levorotatory."

Examples

• Adjective:
  • Dextrorotatory sugars, such as D-glucose, are commonly found in nature.
  • The compound was identified as dextrorotatory because it rotated the plane of polarized light clockwise.

Advanced Usage

• "Dextrorotatory isomer": Refers to one of the two enantiomers (mirror-image forms) of a chiral molecule that exhibits this specific right-handed rotation.
  • The pharmacological activity often differs between the dextrorotatory and levorotatory isomers of a drug.

Variants and Related Words

• Dextrorotation (n): The act or property of rotating to the right.
  • The dextrorotation of the solution was measured with a polarimeter.
• Dextrorotary (adj): A less common synonym for "dextrorotatory."

Synonyms

• Right-handed (in the context of optical rotation).
• d- (chemical prefix).
• (+)- (symbol used in chemical nomenclature).

Antonyms

• Levorotatory (adj): Rotating to the left (counter-clockwise).
• l- (chemical prefix).
• (-)- (symbol used in chemical nomenclature).
