Glycogen metabolism
, Glycogen metabolism
Excess glucose is converted to polymeric form known as glycogen in vertebrate
and starch in plants.
Glycogen is stored in large granules in the cytosol.
Glycogen storage occurs mainly in
Muscles:
− For energy for either aerobic or anaerobic.
− Can be depleted in <1 hour
Liver
− Maintain blood glucose levels
− Only adequate for 12 to 24 hours
Glycogen metabolism is generally the same in both liver and muscles.
Nevertheless, subtle difference do exist in liver and muscles.
