Carbohydrates vs. Starch — What's the Difference?
By Tayyaba Rehman — Published on January 14, 2024
Carbohydrates are a broad class of biomolecules including sugars, starches, and fibers, while starch is a specific type of complex carbohydrate composed of long glucose chains.

Key Differences
Carbohydrates are a major class of biomolecules that include sugars, starches, and fibers, essential for energy in living organisms. Starch, specifically, is a type of carbohydrate that is a polysaccharide composed of long chains of glucose molecules.
Carbohydrates can be simple (like glucose and fructose) or complex (like starch and cellulose). Starch is a complex carbohydrate, typically found in plants, serving as an energy reserve.
The body breaks down carbohydrates into glucose for energy. Starch, being a complex carbohydrate, is digested and broken down into glucose over time, providing a sustained energy source.
Dietary sources of carbohydrates include fruits, vegetables, grains, and dairy products. Starch is abundant in foods like potatoes, rice, and wheat.
Carbohydrates play various roles in the body, including energy storage, structural functions, and being part of cell membranes. Starch, specifically, is mainly involved in energy storage in plants.

Starch
(uncountable) A widely diffused vegetable substance, found especially in seeds, bulbs and tubers, as extracted (e.g. from potatoes, corn, rice, etc.) in the form of a white, glistening, granular or powdery substance, without taste or smell, and giving a very peculiar creaking sound when rubbed between the fingers.
