Starch occurs in two forms, alpha-amylose and amylopectin. Each may be enzymatically hydrolyzed: a-amylose by a-amylase [a(1-4)-glucan 4-glucanohydrolase], present in saliva and pancreatic juice; or by beta-amylase [a(1-4)-glucan maltohydrolase.
The a- and b-amylases also 'attack' amylopectin. Polysaccharides of intermediate length thusly formed are called dextrins.

Why do you suppose that a chloroplast kept in darkeness for some time prior to being fixed for electron microscope does not contain starch?
Chloroplasts require light to perform photosynthesis and produce starch. In the absence of light, chloroplasts cannot convert carbon dioxide into glucose, so there would be no starch present. Starch is a storage form of glucose produced by photosynthesis.
In what form is the energy stored prior to use in respiration?
Energy is stored in the form of glucose molecules in carbohydrates such as starch and glycogen. This energy is then released during the process of respiration to produce ATP, the cell's main energy currency.
What Process in Cellular Respiration requires 2 ATP to be invested?
Glycolysis cannot begin without two ATP molecules to start the process. Glycolysis yields 4 ATP molecules. Therefore, since 2 ATP molecules had been used up prior to the creation of the 4 ATP molecules, glycolysis has a net gain of 2 ATP molecules.
Why is hamburger tested negative for starch?
A hamburger's main ingredient is ground beef, which has no starch. However, there are many methods to prepare the meat prior to cooking it as a hamburger. This can include use of breadcrumbs as a filler, and if these are not used, there most likely is no starch in the hamburger.
Will glucose or sucrose under go more fermentation?
Sucrose is a double sugar and one molecule of sucrose is broken into one molecule of glucose and one molecule of fructose by the yeast (with and enzyme called invertase) prior to fermentation. From a pure chemical reaction perspective 1kg of can produce slightly more alcohol than 1kg of glucose, but given the right environment yeast can fully ferment both. Most brewers yeast prefers glucose to fructose so the glucose will be tend to be consumed first. Glucose is more expensive than sucrose so sucrose is a more cost effective choice.
Why should legumes also be rinsed prior to use?
to remove starch so they stick together so much
What preparation is required prior to a glucose test?
Blood glucose tests require either whole blood, serum, or plasma collected by vein puncture or finger puncture. No special preparation is required for a casual blood glucose test.
Why is potato phosphorylase de-starched prior to its use?
well, its because too much starch in your diet makes you die a horribly painful death.
What checks are to be carried out to ensure all materials required are correct and complete prior to undertaking activity?
broken femur
Why is milk sweet in taste?
That's because the lactose is broken down into two other easily digested sugars which are sweeter: breaks into galactose and glucose... this occurs through hydrolysis in the milk prior to drinking it ( because lactase is found in the milk, which contains lactose), thus creating a sweeter milk).
