What else can I help you with?
What would happen if you added water to a starch molecule?
Adding water to a starch molecule would lead to the hydrolysis of the starch molecule into smaller subunits such as glucose. This process involves breaking the glycosidic bonds between the glucose units in starch through the addition of water molecules. Ultimately, this results in the breakdown of the starch molecule into simpler sugar components.
What molecules are largest glucose starch water or salt?
Starch is the largest molecule among glucose, starch, water, and salt. Starch is a polymer made up of multiple glucose units linked together in a long chain, whereas glucose is a single sugar unit. Water and salt are much smaller molecules compared to glucose and starch.
What is the Solubility difference between starch and glucose?
starch is insoluble whereas glucose is soluble
How do you list these molecules from smallest to largest NaCl Sucrose Water Glucose Starch?
From smallest to largest: NaCl, Water, Glucose, Sucrose, Starch. They are ordered based on their molecular weight and size.
What type of chemical reaction is involved in the digestion of starch and cellulose?
The digestion of starch and cellulose involves hydrolysis, a type of chemical reaction where water is used to break down complex carbohydrates into simpler sugars. Enzymes such as amylase facilitate the hydrolysis of starch into maltose and glucose, while cellulase breaks down cellulose into glucose units. These reactions are essential for the body to convert these polysaccharides into usable energy sources.
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.
What do you add to starch to make glucose?
You would add water through a hydrolysis reaction to reverse the condensation reaction (dehydration synthesis) that you started with to form the starch into a polysaccharide. All in all, you would just add WATER.
Does glucose dissolve easier in water than starch does?
Yes, glucose dissolves much easier in water than starch. Glucose is a simple sugar that readily dissolves in water due to its smaller molecular size and structure. Starch, on the other hand, is a complex carbohydrate made up of many glucose units linked together, which makes it less soluble in water.
Explain in terms of dehydration synthesis and hydrolysis reactions the relationships between starch in an ingested potato liver glycogen and blood glucose?
Starch in an ingested potato is broken down into glucose molecules through hydrolysis reactions during digestion, where water is used to cleave the glycosidic bonds between glucose units. Once absorbed, glucose can be utilized for energy or stored as glycogen in the liver via dehydration synthesis, where glucose molecules are linked together, releasing water. When blood glucose levels drop, glycogen can be hydrolyzed back into glucose, maintaining glucose homeostasis in the bloodstream. Thus, starch, glycogen, and blood glucose are interconnected through these biochemical reactions.
What is the hydrolytic product of starch?
glucose maltose and maltotriose
How can you tell if glucose starch water and iodine passes through the cell membrane?
If the glucose, starch, and iodine pass through the cell membrane, you can perform a color change test. The presence of glucose will show a positive result with Benedict's reagent turning orange/red. The presence of starch will show a positive result with iodine turning blue/black.
How do you separate cellulose from a mixture of glucose starch and cellulose?
Cellulose can be separated from a mixture of glucose, starch, and cellulose through a process called filtration. Cellulose is insoluble in water, while glucose and starch are soluble. By mixing the mixture with water and filtering it, the cellulose will be left behind on the filter paper, while the glucose and starch pass through as a solution.
