More energy for doing work. Eat energy for cooking food or for keeping us warm is supplied by burning wood, charcoal, gas, oil, coal, peat, and electricity. Mechanical energy for driving a motor car is produced from petrol.
The fire has to have more wood and the car more petrol to keep them going. The body too needs fuel regularly to provide the energy required for all the purposes.

Energy exists in the most important monosaccharides nutritionally which are the simple sugars. There are three different sugars such as free glucose which does not occur in any quantity in foods except in grapes.
Others are fructose which occurs in some fruits and in honey and galactose which is found in a combined form in milk sugar called lactose.
This is vital that when green plants make their own food from carbon dioxide and water, the first stage in the process is the formation of simple glucose. This shows that for a simple formula when carbon dioxide is added with water, it results in glucose and oxygen.
A more complex sugar can be formed from a combination of two monosaccharides. There are three disaccharides occurring in foods for instance sucrose is the sugar we use in the home.

It occurs naturally in cane and beet which are used to make commercial sugar. When one molecule of fructose and one molecule of glucose combine to make the disaccharide sucrose. Water is given off.
On the other hand, lactose is the sugar present in milk and is derived from the two monosaccharides consisting of glucose and galactose. This is important to know that sugars are soluble in water.
This is an important property as a substance must be soluble in water before it can be absorbed by the blood and used by the body for the supply of energy.
Starch is a source of energy. Starch is a polysaccharide present in all staple foods as the starch grain contains polysaccharides derived from very many glucose molecules.

Most foods rich in starches contains other food nutrients, such as proteins, vitamins, and minerals which are important to the body, but sugar is pure carbohydrate with no other nutrient.
The advantage that starches have over sugar is that a lot of sugar intake is capable of causing teeth decay while starches are the cheapest and most economical food for providing energy.
Other sources of starch are roots, tubers, and stems, such as cassava, potatoes, sweet potatoes, yams, arrowroot, and their products, tapioca, sago.
Legumes and pulses, such as beans, lentils, peas, and grams supply some carbohydrates, but they contain another nutrient, protein is a good source of carbohydrates.
Sugars are found naturally in fruits, honey, some vegetables, such as carrots and sweet potatoes, and in sugar-cane and sugar-beet, from which sugar is made commercially.

In conclusion, Fat is another nutrient that is a good source of energy. In fats, the proportion of hydrogen to oxygen is greater than in components of monosaccharides comprising glucose, fructose, and galactose disaccharides comprising sucrose, lactose, and maltose.
