Glucagon works in a manner that is generally opposite to insulin. It will labor to increase blood glucose concentration, thereby returning it toward normal levels (see Blood Glucose and Hormone Table).To accomplish this, glucagon promotes the breakdown of liver glycogen to glucose, which is released into circulation.lucagon works in a manner that is generally opposite to insulin.

Sucrose, or table sugar, is just one type of carbohydrate. Sucrose, glucose and starch are related because they're all forms of carbohydrate. One of the essential macronutrients in foods along with protein and fat, carbohydrates supply energy to your body. Carbohydrates, which consist of carbon, hydrogen and oxygen, are classified according to their chemical makeup.
The three types of carbohydrates in your diet -- sugar, starch and fiber -- all consist of sugar. Simple sugars, such as sucrose, fructose and lactose, only have one or two molecules of sugar. Starch and fiber are complex carbohydrates because theyâre made from three to hundreds of sugar molecules.During digestion, simple sugars and complex starches break down into single molecules of glucose.imple sugars, such as sucrose, fructose and lactose, only have one or two molecules of sugar.
