Family Betulaceae â Alder, Birch, Hornbeam. The birches have long been popular ornamental trees in North America, chiefly in the northern United States and Canada. Several are native Americans, but many species have been introduced from Europe and Asia.
Carbohydrates-Simple sugars are sent to the liver where they are converted to glucose. The glucose then travels to the blood or is converted to glycogen and fat (triglyceride). The glycogen and fat will be stored in the liver and adipose tissue, respectively, as reserves for the post-absorptive state.
Glycogen is found in the form of granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle. Glycogen forms an energy reserve that can be quickly mobilized to meet a sudden need for glucose, but one that is less compact than the energy reserves of triglycerides (lipids). In the liver, glycogen can make up from 5â6% of the organ's fresh weight (100â120 g in an adult).
