- Meats are good sources of proteins and fats and oil.
- The fat and oil is processes by the bear in the digestive system into fatty acids.
- Fatty acid are essential materials that are used in making the cell membrane.
- The cell membrane is rich a phospholipid layer that keeps the shape of the cell intact.
- When fatty acid is lacking, the cell will suffer and the cell membrane can collapse.
