I'm just confused

    Glycogen is a polymer of glucose molecules used for energy storage. The liver is the organ primarily involved in glycogen synthesis (skeletal muscle also does this somewhat). Whenever there is too much glucose flowing through the blood, such as after a meal, this extra glucose is sent to the liver to be put together as glycogen. Whenever cells of your body need glucose, such as during exercise or stress, the liver breaks down the glycogen into glucose monomers to be sent to those cells in need.

    Glycerol is mainly used as the backbone for fats. The scientific term for fat is triacylglycerol or triglyceride. Whenever you add 3 fatty acids to a glycerol, you make triglyceride. This is the main job of the adipocytes (fat cells).

    So both glycogen and glycerol are involved with energy storage: glycogen stores energy in the form of carbohydrates while glycerol is a molecule involved in fat storage.

    Fats are broken down in the small intestines into fatty acids and glycerol.

    Glycogen is the storage form of glucose for animals.

    Glycogen is a polymer of glucose.

    Glycerol is a three-carbon compound(trihydric alcohol) which may be used for the synthesis of fat.

    Confusing because they both begin with "glyc", I presume.

    The prefix, glyc, always refers somehow to sugars.

    Glycogen is a chain of sugars (glucoses) that is stored in liver and muscle cells, for example.

    Glycerol is like a 3-carbon sugar, except that it has 3 alcohol groups (1 on each carbon),

    instead of 2 alcohol groups and an aldehyde.

    But the result is that they are totally different molecules, and play totally different roles in the body, indeed in all living cells - as described by several others above..

    they are two different things, glycogen is a polysaccharide, glycerol is C3O3H8
