Linkage between sugar and carbohydrates

Sugars are a type of carbohydrate, specifically classified as simple carbohydrates or simple sugars. They consist of one or two sugar units, such as glucose and sucrose. In contrast, complex carbohydrates are made up of longer chains of sugar molecules, including starches and fibers. Both types of carbohydrates serve as important energy sources for the body, but they differ in their structure and how quickly they are metabolized.
