D Vs L Sugars In Ring Form - A d sugar can be either dextrorotatory or levorotatory. This concept is most easily seen with glyceraldehyde. Web thus, an l sugar is the mirror image (enantiomer) of the corresponding d sugar and has the opposite configuration from the d sugar at all chirality centers. Web the confusion about d and l arises because the l sugars of a given name (glucose, for example) are mirror images of the d sugars of the same name.
