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.
The potato does not store sugar because there is no sugar in it. The plant has starch in it which is then turned into "sugar" when it is eaten and digested. -when starch is digested, it turns to glucose. The organelle holding the startch grains are called leucoplasts.
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.
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.
Sugar dissolves very well in water (>65%) while starch only 'absorbs' water (slimy starch or glue) whithout dissolving. Cellulose (paper, cotton) is insoluble.
Starch is more soluble in water than in sugar. Starch molecules can absorb water and swell, forming a colloidal suspension in water. On the other hand, sugar dissolves readily in water to form a homogeneous solution.
Germinating barley grain releases an enzyme that converts starch to maltose.
The digestion of starch begins in the mouth during mastication. The ptyalin enzyme (an amylase) converts the starch to sugar .
The simple sugars are most easily stored as starches, and the breaking down of these starches is what releases the energy the plant needs to survive. Actually, it is necessary to store the sugars in some insoluble forms, you know a soluble form of sugar cannot be stored in cells since it imbalances the osmoticum of cells. Starch is insoluble and more stable, so plants prefers to store the sugars in the form of starch converts to sucrose and other soluble sugars whenver needed.
Amylase in the mouth made by the salivary gland turns starch into sugar.I remember it withAmylaseStarchSugar
the enzyme ptylin or some amylase and it converts starch to maltose

no, starch is sugar fool
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.
Starch is a polysaccharide ie. a very complex carbohydrate. Enzymes break it down into a di-saccharide - maltose. Another enzymes then converts this into the monosaccharide (simple sugar), glucose.
