[The fine structure of trout liver glycogen]. / La structure fine du glycogène hépatique de la truite arc-en-ciel.

1. The fine structure of trout liver glycogen has been investigated using an enzymatic method. 2. The total conversion of glycogen into glucose under the action of amyloglucosidase and the percentage of beta-amylolysis before (37.4%) and after (97.8%) isoamylase debranching are similar to the mammalian glycogen. 3. However, the resistance to beta-amylase of certain debranched material leads to an hypothesis during glycogenolysis.
