Question

2 main function of carbohydrates

Answer 1

Introduction. Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.

Answer 2

Answer:-  FUNCTIONS OF CHARBOHYDRATES:

1.   Provide Us with Energy

The main thing carbohydrates give us is the energy for metabolism. This is why dieticians recommend that more than half of our calories should be supplied in the form of carbs. Some carbs are used immediately for cellular processes, while excess carbs are stored in the form of glycogen, which is present in the liver. Some carbs turn into fat and are stored in our fat cells.

2.   Use Protein in Other Beneficial Ways

Without the functions of carbohydrates, our body would have to use protein for fuel. Protein, however, is necessary for other cellular processes and when it is wasted as fuel, we have less protein for the repair of tissues and for the production of enzymes. Carbs allow our body to use protein for what its primary purpose is and not just for fuel.

3.   Are Necessary for Fat Oxidation

The body needs carbs in order to burn fat. A breakdown product of carbohydrates is called oxaloacetic acid, which is necessary to metabolize fats. Without this breakdown product, fats get turned into ketones, which can be toxic to the bodies. This is why we need carbs in order to allow fats to be metabolized correctly by the body.
