The iodine-staining properties and fine structure of some mammalian and invertebrate glycogens.
Glycogens from mammalian and invertebrate sources have been compared by measuring the iodine-staining spectra of the debranched polymers and the debranched beta-amylase limit dextrins. From the results, it is concluded that, whereas the interior chains of each group of glycogen are very similar, the exterior chains of the mammalian glycogens generally contain a small number of longer chains which are not found in the invertebrate glycogens.
