                          Bread has chemical energy

• Bread has chemical energy stored in it because of the chemicals or the nutrients stored in it.

• Made from wheat or other grains, it is a rich source of carbohydrate and various other nutrients like proteins, fat, vitamins and minerals.

• The carbohydrates in the bread can yield about 920 KJ or energy per 100 g of bread which is converted into ATP molecules in our body through metabolism.
• Baking of bread includes many chemical processes like yeast activity, gluten coagulation, amylase activity, Maillard reaction, and sugar caramelization all of which releases energy that is stored in the bread.
