Differentiate between a sugar and a starch?

Answer 1

Plants store glucose in the form of starch.Starch can be separated into two fractions-amylose and amylopectin. Natural starches are mixtures of amylose (10-20%) and amylopectin (80-90%) Starch is a polymer of glucose molecules. It consists of a mixture of 2 polysaccharides:
25% amylose - about 2000 glucose residues are linked by the alpha 1-4 glycosidic linkage. It is unbranched and forms a helix.
75% amylopectin - branched chains about 100000 glucose units. Glucose is joined by the alpha 1-4 glycosidic linkage and at branched points the alpha 1-6 glycosidic linkages occur.

Answer 2

Sugars are simple carbohydrates made of one or two sugar molecules, while starch is a complex carbohydrate made of multiple sugar molecules linked together. Sugars provide quick energy, while starch is a longer-lasting source of energy, as it takes longer to break down. Examples of sugars include glucose and fructose, while examples of starches include potatoes and grains.

Answer 4

Glycogens are a macromolecules composed carbon (C) hydrogen (H) and oxygen (O). The molecular formula of glycogen is C24H42O21. A Glycogen is two carbon rings bonded to others in repeating chains.

Answer 5

A simple sugar is only one or two molecules. Starch is a complex sugar that is made of thousands of glucose molecules bonded together. Glucose is the simple sugar that is the main fuel for living things. Starch molecules store glucose for when it is needed.

Answer 6

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.

Answer 7

a structural formula depend upon it's corban, hydrogen and oxygen atom's bonds.

Answer 8

Sugar: a sweet substance obtained from various plants.

Starch: An odorless, tasteless white substance.

Answer 9

A long chain of glucose, maltose, fructose etc.. molecules joined together by glycosidic bonds that are made in condensation reactions (the removal of water)

Answer 10

Starch is a polymer formed from glucose monomers linked by glycosidic bonds.
