1. Rat liver glycogen was separated into fractions of relatively uniform particle sizes by large volume rate-zonal centrifugation of tissue homogenates with the use of sucrose density gradients. 2. After centrifugation, the distribution curve obtained by plotting the glycogen content of all collected fractions exhibited its maximum a short centrifugal(More)
Both single and multigrain U-Pb zircon thermal ionization mass spectrometry (TIMS) as well as sensitive high resolution ion microprobe (SHRIMP ll) dating of two suites of Adirondack granites have yielded ages constraining the principal tectonomagmatic events of the Ottawan Orogeny to the interval ca 1090–1035 Ma. The earliest of these consists of mildly(More)
1. A differential incorporation of 14C-glucose into two distinct molecular weight fractions of glycogen from the tapeworm Hymenolepis diminuta has been observed. Changes in these labeling patterns as a function of the glycogen level have been examined. 2. After incubation of Hymenolepis diminuta in media containing 14C-glucose under steady state conditions(More)
Extraction of glycogen from rabbit liver and from Ascaris muscle at low temperatures and without the use of alkali or acid yields a product, the sedimentation characteristics of which differ considerably from those of glycogen isolated by more drastic procedures (1). Glycogen extracted with cold water not only exhibits a markedly higher weight average(More)
