It's because starch is a polysaccharide. A polysaccharide has thousands and thousands of monosaccharides bonded together. All those bonds make the starch hard to break apart and dissolve in water.
When glucose, made in photosynthesis, is turned into an insoluble compound, it is stored as starch in plants. Starch is a polysaccharide composed of glucose units linked together in a way that makes it insoluble in water and suitable for long-term storage of energy.
An mylopectin is a variety of highly branched, insoluble form of starch.
Firstly what the end products of the starch converting to glucose are soluble. Starch is converted to alpha glucose monomers by the addition of water to the glycosidic bonds which join the glucose molecules together. This addition of water is a hydrolysis reaction and seperates the glucose molocules form the starch polymer. The enzyme amalayse is responsible for catalysing the break down of starch into SOLUBLE glucose molecules (monomers).
Sugar dissolves very well in water (>65%) while starch only 'absorbs' water (slimy starch or glue) whithout dissolving. Cellulose (paper, cotton) is insoluble.
sugars and starch are both made only of carbon, hydrogen and oxygen that is insoluble in cold water or alcohol
Starch is insoluble in water and so can be used as a storage device for glucose; plants convert the spare glucose into starch then store it.
corn starch is insoluble in water. Cornstarch is not an element!
Starch
When glucose, made in photosynthesis, is turned into an insoluble compound, it is stored as starch in plants. Starch is a polysaccharide composed of glucose units linked together in a way that makes it insoluble in water and suitable for long-term storage of energy.
starch is insoluble whereas glucose is soluble
Glycogen, starch, and cellulose are all large carbohydrate molecules.
Because it is insoluble in water.
Well, Starch is a storable carbohydrate and the fact that it's insoluble just means it will not dissolve in water.
Starch is a complex carbohydrate therefore it cannot be used and is insoluble unless it is broken down. Also the body requires glucose for important metabolic functions (respiration) to provide energy for the body, starch cannot be used for this process.
