Sugar, in easy terms, is a simple carbohydrate. Once you are categorizing simple carbohydrates, their names end with the ‘-ose’ suffix. For example, blood sugar is known as monosaccharide glucose in medical science. Similarly, medical experts call milk sugar as disaccharide lactose. Other examples include disaccharide sucrose, which is the medical term for the sugar which human beings consume in their daily regime. With a simple structure, sugar is easy to consume for the human body and that is why it does not take much time for the digestive system to absorb it.

Carbohydrates can be divided into four simple groups: Monosaccharide, Disaccharides, Oligosaccharides and Polysaccharides. Out of these four, the first two, Monosaccharide and Disaccharides, are considered to be simple carbohydrates. Sugar falls under the category of these two groups of carbohydrates. On the other hand, the other two groups, Oligosaccharides and Polysaccharides, can be referred as starches. The human body requires a lot of time in order to break these two complex groups down in order to convert them into energy. These two complex groups consist of more than three sugars at the same time.
