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.

∙ 10y agoBecause starch is insoluble, it can more easily be stored by living organisms, whether plant or animal. Soluble substances are harder to control; they go into solution in blood, sap, lymph, or whatever, and then they are subject to osmotic pressure and wind up being excreted in the urine, and so forth. Insoluble compounds stay where they are put.

When Glucose made in photosynthesis is turned into an insoluble compound what is this compound?
Starch
What is an amylopectin?
An mylopectin is a variety of highly branched, insoluble form of starch.
What is the significance of starch polysacchride?
Storage of food in plants. As starch is insoluble and compact, it is the most ideal form for storage in plants. For animals, starch is a source of carbohydrate. Therefore source of energy.
What converts insoluble starch to insoluble sugar?
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).
Why does a plant need starch?
Glucose is soluble in water and starch is insoluble in water. So for storage in a rather wet medium such as a plant cell, glucose is changed to insoluble starch. When the plant needs glucose for respiration or other processes it changes the starch back to soluble glucose for transportation in solution through the phloem system.
Why starch is a good storage compound in plant?
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.
Is starch more soluble in water or sugar?
Starch is insoluble in water.Sugar reedily soluble
What is the Solubility difference between starch and glucose?
starch is insoluble whereas glucose is soluble
What is the solubility of corn starch in water?
corn starch is insoluble in water. Cornstarch is not an element!
What is the name of an insoluble carbohydrate used for storage?
Starch
Why starch is a good compound in plant?
Because it is insoluble in water.
What is the insoluble carbohydrate with big molecules?
Glycogen, starch, and cellulose are all large carbohydrate molecules.
Why is the digestion of starch to glucose necessary?
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.
What is insoluable starch?
Well, Starch is a storable carbohydrate and the fact that it's insoluble just means it will not dissolve in water.
When Glucose made in photosynthesis is turned into an insoluble compound what is this compound?
Starch
What is an amylopectin?
An mylopectin is a variety of highly branched, insoluble form of starch.
