How are starch and glycogen similar and how do they differ?
Startch have two types of polymer chain,one is amylose and another is amylopectin.Amylose is simple straight chain of glucose(1--->4 linkage),while amylopectin have branching.At branching point,there is 1--->6 linage and 1--->4 linkage in every subchain. So,in startch 1-6 linkage comes after 20 to 25 gucose monomer,while in gycogen this linkage comes very frequently.....
Why is there starch in water?
Starch in water may occur during cooking when starch-containing foods are rinsed or soaked in water. Starch granules can release into the water due to mechanical action or heat, resulting in a cloudy appearance to the water.
What best explains how the structure of starch molecule relates to its function?
The structure of the starch molecule, which is made up of long chains of glucose units, allows it to be easily broken down by enzymes in the body to provide a steady source of energy. The branching nature of starch molecules also makes them compact and easily stored in plant cells. This structure enables starch to efficiently store and release glucose molecules as needed for energy.
How does the structure of starch make it suitable for its function?
Starch is made up of repeating glucose units arranged in long chains, allowing for compact storage of energy. The branching in its structure provides more ends for enzyme action, aiding in the rapid breakdown of starch into glucose for energy release. This structure also allows starch to be insoluble in water, preventing osmotic issues in plant cells.
Why branching decay occur in thorium series?
Branching decay occurs in the thorium series because there are multiple pathways for the decay of thorium nuclei. Thorium can decay through alpha decay, beta decay, gamma decay, and other processes, leading to different end products with varying probabilities. These branching decay pathways contribute to the overall complexity of the thorium decay chain.
Why is starch phosphorylase not involved in vivo starch anabolism?
Starch phosphorylase is primarily involved in starch degradation by catalyzing the conversion of starch to glucose. In vivo starch anabolism involves the synthesis of starch molecules from glucose, which is carried out by enzymes like starch synthase and starch branching enzyme. Therefore, starch phosphorylase is not directly involved in the biosynthesis of starch in living systems.
Does gelatinisation occur in pancakes?
Yes gelatinisation does occur in pancakes. Gelatinisation is when granules absorb water and swell. It is when starch grain mix in with a liquid and heat the starch. Pancakes have starch in them and therefore gelatinisation does occur.
What is the different between animal and plant starch?
Animals do not store glucose in starch molecules, but rather in glycogen molecules. Starch molecules have infrequent branching of glucose chains and as such are not readily broken down into glucose monomers by the enzymes that catalyze the reaction. Glycogen molecules follow the same basic structure as starch molecules, but instead have more branching and consequently are broken down easier. This allows for quicker "burst" energy and is better suited to animals' mobility.
Is a starch molecule a straight chain or is it branching?
THERE ARE TWO POSSIBLE REASON 1)Animal require a high amount of energy so in glycogen there are many terminal ends ,due to high branching ,so in a given time more number of glucose can be detached and consequently used for energy while in plant high amount of energy at a given instant is not required so no or less branching is there in starch 2)in animal less space is presnt so glycogen is highly branched to occupy less space while in plants there is no limitation of space so starch is less branched

Is the difference between glycogen and starch?
Glycogen is the storage form of glucose in animals, while starch is the storage form of glucose in plants. Both glycogen and starch are polysaccharides made up of glucose units, but they differ in the branching pattern of their glucose chains and the enzymes involved in their synthesis and breakdown.
Why would hydrolysed starch test negative in iodine testing?
Hydrolysed starch would test negative in iodine testing because hydrolysis breaks down the starch into smaller sugar molecules like glucose, which no longer have the characteristic branching structure of starch that allows iodine to bind and form a blue-black complex. Therefore, with hydrolysed starch, there would be no starch molecules left to react with iodine and show a color change.
What digestive function can occur in the mouth?
Starch can be converted into sugars in the mouth.
What are the differences between the amylose and amylopectin structures in terms of their molecular composition and branching patterns?
Amylose and amylopectin are both polysaccharides found in starch. Amylose is a linear molecule made up of glucose units linked together in a straight chain, while amylopectin is a branched molecule with glucose units linked in a branched structure. Amylose has -1,4 glycosidic bonds, while amylopectin has both -1,4 and -1,6 glycosidic bonds, which create branching points in the molecule. This difference in branching patterns affects the overall structure and properties of these two starch components.
Glucose is to a starch as a. a steroid is to a lipid b. a nucleotide is to a nucleic acid c. an amino acid is to a protein d. a polypeptide is to an amino acid?
an amino acid is to a protein. ie starch is made of a chain of glucose with side branching. aa's combine to make a protein, to simplify things
Can Active transport help starch molecules through a membrane?
No, active transport is a process that requires energy to move molecules against their concentration gradient. Starch molecules are too large to be transported through a membrane using active transport. Starch molecules are typically broken down into simpler sugars before they can be transported across a membrane.
Why is there starch in water?
Starch in water may occur during cooking when starch-containing foods are rinsed or soaked in water. Starch granules can release into the water due to mechanical action or heat, resulting in a cloudy appearance to the water.
