                                Approximately 180–220 grams of glucose are produced daily in the liver of an adult. For most practical purposes, when people refer to "glucose," they are referring to D-glucose, the form used by nearly all living organisms. However, the two terms are not technically identical, as the 'D' is a specific chemical descriptor.
