role of carbohydrates
Carbs Store Energy for Later. This form of carbohydrate plays an important role in keeping your energy levels up between meals. Since blood sugar levels must remain constant, the body converts glycogen to glucose when blood sugar levels dip. This brings blood sugar back up to normal and keeps it within a tightly controlled range.
Physiology textbooks refer to this so-called role or function of carbohydrate in the body as “its protein-sparing action.” However, it is incorrect to attribute action (other than chemical action) to carbohydrates or other inanimate substances. Besides, “sparing protein” is not a function or role of carbohydrates at all.
Functions of Carbohydrates. This blood sugar, or blood glucose, is transported through your bloodstream to supply energy to your muscles and other tissues. This is an important process; in fact, we could say that of the different functions of carbohydrates, supplying energy to the body is the main role.
Carbs are controversial, but no matter where you fall in the debate, it’s hard to deny that they play an important role in the human body. This article highlights the key functions of carbohydrates.
Carbohydrates play a role in the production of B complex vitamins made by beneficial bacteria in the body. The beneficial bacteria live off the carbohydrates consumed by the GI tract and can then help us in return by producing valuable vitamins we need to function.
Energy Production. The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.
Carbohydrates can be either simple or complex. Simple carbs are both sugars and some forms of starch, such as white rice. Simple carbs are both sugars and some forms of starch, such as white rice.
Carbohydrates play an especially important role as they provide the quick energy needed for exercise. Carbohydrates, found in foods like grains, fruits, vegetables, beans, and dairy products, are your body’s favorite source of energy, but this is not the only role that carbs play.
