Excess glycogen is converted into triglycerides or fats by the liver, which are stored in different boy tissues. Fats can also be ingested from foods (Houston, 2006). They are broken into non-esterified fatty acids, which are carried by albumin into the cells.
The cells can use these fatty acids as source of energy or convert them back to triglycerides that will be deposited to different tissues for later use. The fats are especially stored in certain fat cells called adipocytes though they may also be present in muscle cells (Houston 2006). Fats are water insoluble. They are made of glycerol and three fatty acids (Martin and Coe 1997).
