What is the difference between a starch and a carbohydrate?

Question

Can someone explain to me the difference between a starch and a carbohydrate? I'm kinda confused on what the difference is between these foods. Starches are potatoes and corn....carbohydrates are pastas and breads.....yes..but what is the actual diffference between those types of foods. Why do they have their own seperate groups?

Answer 1

There are three basic types of carbs: (1) starchy carbohydrates (polysaccharides); (2) sugars (monosaccharides or disaccharides) and (3) dietary fiber (polysaccharides). Carbs are one of three main food nutrients: the others being protein and fat.

Starch is a type of carbohydrate. Carbohydrates are the broad term that covers mono and disaccharides, sugar alcohols, polysaccharides (starch) and dietary fiber. These are all digested, with the exception of fiber. Starch is comprised of long chains of the monosaccharide glucose. It can be a straight chain called amylose, or a branched chain called amylopectin. Actually cellulose and chitin dietary fiber not starches as they are resistant to digestion by human enzymes, thus cannot be starch.

Answer 4

Carbohydrates is a comprehensive term that covers six carbon saccharide units such as glucose or fructose (which chemically are aldehydes or ketones containing many hydroxyl groups) and all substances built from them. Starch is a polymer of glucose (many glucose molecules linked in a chain that can be straight or branched, ie glucose is the monomer that builds starch molecules) and in order to be absorbed it needs to be broken down to its constituent glucose units something achieved to an extend by the enzyme amylase secreted in the mouth but most starch digestion occurs in the small intestine with pancreatic amylase. The disaccharides sucrose (1 glucose + 1 fructose unit), maltose (2 glucose unit) and lactose (1 glucose + 1 galactose unit) are also broken down to their constituents before absorption can occur, by sucrase, maltase and lactase respectively.
