Various toxins can impact glycogen storage, including ethanol, which is known to affect liver function and glycogen metabolism. Similarly, aflatoxins, produced by certain molds, can cause liver damage, impeding glycogen storage. Certain heavy metals, such as lead and mercury, have also been implicated in disrupting glycogen metabolism. Additionally, some pharmaceutical drugs can alter glycogen storage as a side effect, highlighting the importance of understanding these interactions in clinical toxicology.
