OPTICAL ISOMERS - DIFFERENCE isomers differ in their reaction to plane-polarised light plane polarised light vibrates in one direction only one isomer
{"Image DocumentName": "OPTICAL ISOMERS - DIFFERENCE", "Image ImageDescription": "isomers differ in their reaction to plane-polarised light. plane polarised light vibrates in one direction only. one isomer rotates light to the right, the other to the left. rotation of light is measured using a polarimeter. rotation is measured by observing the polarised light coming out towards the observer. If the light appears to have turned to the right turned to the left. DEXTROROTATORY LAEVOROTATORY. d or + form l or - form. Racemate a mixture of the two enantiomers (dl) or (\u00b1) is a racemic mixture. The opposite optical effects of each isomer cancel each other out. Examples Optical activity is common in biochemistry and pharmaceuticals. \u2022 Most amino acids exhibit optical activity. \u2022 many drugs must be made of one optical isomer to be effective. - need smaller doses (safer and cost effective) - get reduced side effects. - improved pharmacological activity.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
