Editing Glycogen (section)

==History==
Glycogen was discovered by [[Claude Bernard]]. His experiments showed that the liver contained a substance that could give rise to reducing sugar by the action of a "ferment" in the liver. By 1857, he described the isolation of a substance he called "''la matière glycogène''", or "sugar-forming substance". Soon after the discovery of glycogen in the liver, M.A.&nbsp;Sanson found that muscular tissue also contains glycogen. The empirical formula for glycogen of ({{chem|C|6|H|10|O|5}})<sub>n</sub> was established by [[August Kekulé]] in 1858.<ref>{{cite journal |first=F.G. |last=Young |date=22 June 1957 |title=Claude Bernard and the discovery of glycogen |journal=British Medical Journal |volume=1 |issue=5033 |pages=1431–1437 |jstor=25382898 |doi=10.1136/bmj.1.5033.1431 |pmid=13436813 |pmc=1973429}}</ref>
