Carbohydrates vs. Starch: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 30, 2024
Carbohydrates are a broad class of biomolecules including sugars, starches, and fiber; starch is a complex carbohydrate consisting of glucose units.

Key Differences

Carbohydrates are a major class of biomolecules that include sugars, starches, and fibers, serving as a primary energy source in diets. Starch, specifically, is a type of complex carbohydrate made up of long chains of glucose molecules.

Carbohydrates encompass a wide range of molecules from simple sugars like glucose and fructose to complex forms like cellulose and starch, while starch is specifically a storage form of energy in plants and is composed of two types of molecules: amylose and amylopectin.

Carbohydrates can be divided into simple carbohydrates (sugars) and complex carbohydrates (starches and fibers), with the latter being more beneficial for sustained energy release. Starch, as a complex carbohydrate, is digested more slowly, providing a more gradual supply of energy.

In human nutrition, carbohydrates are essential for providing energy, supporting bodily functions, and dietary fiber. Starch is a key component of many staple foods like potatoes, rice, and wheat, and is a major source of energy.

Carbohydrates are also involved in various biological processes, including cellular communication and immune response. Starch, meanwhile, plays a crucial role in plant physiology as a way to store energy for later use.
