Turning or rotating the plane of polarization of light towards the left; -- applied to crystals and compounds exhibiting optical activity, such as levulose, left-handed quartz crystals, etc. Opposite of dextrorotatory.

Describes compounds that rotate plane-polarized light to the left (counterclockwise) when viewed in the direction of the light source. See dextrorotatory.

Compare with dextrorotatory. Having the property of rotating plane-polarized light counterclockwise.

Having the ability to rotate the plane of vibration of plane-polarized light to the left

rotating to the left

A term applied to optically active compounds that rotate plane poloraized light counterclockwise or to the left.

Able to rotate plane-polarized light in a counterclockwise fashion.

A chiral molecule which rotates plane polarized light to the left

Refers to an optically active substance that rotates the plane of plane polarized light counterclockwise; also called levo.
