Starch is a polysaccharide, consisting of a long chain of simple sugars, which are also referred to as monosaccharides or disaccharides. Monosacharides are made up of a carbon ring, with all but one of the carbons in the ring being bonded to a hydroxyl (OH); the last carbon is doubled bonded to an oxygen. Disaccharides are simple sugars consisting of two adjoined monosaccharides.

As the prefix of the names suggest, a polysaccharide is made up of many (thousands) of monosacharides and/or disaccharides. Rather than maintaining the monosacharide's ring-like structure, polysaccharides--such as starch--form a chain of carbon rings. In actuality, there will be chains branching off of the theoretical chain. Starch will usually arrange its chains in a semi-crystalline structure.

Does a carbohydrate have to be both starch and sugar or can it be just starch or sugar?

Carbohydrates are made up of a large group of organic compounds which include both starch and sugar. Sugar is the simplest form, and they supply energy to living cells for respiration. Sugar can be stored as starch (which is insoluble). Starch can be broken down into sugar when it is needed for respiration. Both sugar and starch are carbohydrates.Carbohydrates are usually classified into 4 categories:monosaccharides (aka simple sugars) like glucose, fructose, galactose, ribose, and xylosedisaccharides like sucrose, lactose, and maltosedigestible polysaccharides like amylose (aka starch), and glycogenindigestible polysaccharides (aka fiber) like cellulose, chitin, and peptidoglycanAll are composed only of the elements carbon, hydrogen, and oxygen.


Is glucose starch?

No, glucose and starch are different molecules. Starch is a polysaccharide made up of multiple glucose molecules linked together. Glucose, on the other hand, is a simple sugar and the primary source of energy for living organisms.
