How are simple sugars and complex carbohydrates similar?

Simple sugars and complex carbohydrates are both types of carbohydrates that provide energy to the body. They share a common chemical structure, consisting of carbon, hydrogen, and oxygen atoms. Both forms can be broken down into glucose, which is used by the body for fuel. However, they differ in their structure and how quickly they are digested and absorbed, with simple sugars being quickly absorbed and complex carbohydrates taking longer to break down.
