Glycogen metabolism in glycogen-rich erythrocytes.
High concentrations of red blood cell glycogen were visualized by el.ctron microscopy and demonstrated biochemically in amylo1 ,6-glucosidaseand phosphorylase-deficient red blood cells. Glycogen concentration decreased as a function of cell age. Similar incorporation rates of ‘4C-U-glucose into glycogen were observed in amylo-1 ,6-glucosidase-deflcient and normal erythrocytes, characterized by ...
متن کاملGlucose and glycogen metabolism in erythrocytes from normal and glycogen storage disease type III subjects.
Active glycogen metabolism has been demonstrated in both normal and glycogen-rich erythrocytes taken from patients with type III glycogen storage disease. Activity of all enzymes catalyzing the reactions required for the synthesis and degradation of glycogen have been demonstrated in the mature erythrocytes. Uniformly labeled glucose-(14)C is incorporated into glycogen in intact cells of both t...
متن کاملGlycogen metabolism in humans☆☆☆
In the human body, glycogen is a branched polymer of glucose stored mainly in the liver and the skeletal muscle that supplies glucose to the blood stream during fasting periods and to the muscle cells during muscle contraction. Glycogen has been identified in other tissues such as brain, heart, kidney, adipose tissue, and erythrocytes, but glycogen function in these tissues is mostly unknown. G...
متن کاملCytosolic & Lysosomal Glycogen Metabolism
It is now well established that the metabolism of glycogen in the l iver p roceeds h y d r o l y t i c a l l y through the lysosomal compar tment (Geddes & Taylor, 1985; Geddes et al .~ 1983; Geddes & Stratton~ 1977a,b; LCillman-Rauch 1981, 1982; Knecht & Hernandez, 1978; Brown et al., 1978; Rybicka, 1981) as well as through the well-established s y n t h e t i c phospho ry ly t i c pathways (C...
متن کاملGlycogen Metabolism and Meat Quality
pHu of meat is an index of high quality since it is associated with a bright red colour, increased tenderness, increased flavour and increased keeping and cooking qualities. Few studies have examined glycogen level and/or metabolism directly in meat producing animals. Instead most studies have examined the pHu of meat as an index of glycogen metabolism. This is unfortunate since the pHu of meat...
