12 Questions
What is the primary function of starch in plants?
To store energy for the plant
What is the chemical formula of the starch molecule?
(C6 H10O5)
What is the difference between amylose and amylopectin, the two polymers that make up starch?
Amylose is linear, while amylopectin is branched
How does the human body utilize the starch obtained from plant sources?
The body breaks down the starch molecules into glucose, which is the body's primary fuel source
What is the role of the enzyme amylase in the digestion of starch?
Amylase breaks down the 1,4 glycosidic bonds in amylose and amylopectin, converting starch to glucose
What is the primary source of starch in the human diet?
Plant sources, such as grains, vegetables, and tubers
What is the main difference between amylose and amylopectin in terms of structure?
Amylose has a linear structure, while amylopectin is branched.
Why does amylopectin have more accessible ends compared to amylose?
Due to the presence of occasional 1,6 glycosidic bonds.
What distinguishes waxy starches from regular starches?
Waxy starches contain 100% amylopectin.
How does the size of starch granules affect their thickening ability?
Larger granules can swell more and therefore thicken more effectively.
What factor influences the gelatinization temperature range for starches?
The percentage of amylopectin and amylose in the starch composition.
How does stirring affect the gelatinization process of starch?
Agitation during stirring can cause premature rupture of starch granules.
Learn about the complex carbohydrates starches and glycogen, their role in providing energy, and how they are synthesized in plants and animals. Understand the composition of starch, including amylose and amylopectin, as well as the structure of glycogen.
