The structural difference between amylose and amylopectin?
Amylose is type of starch which is unbranched. Consisting 1-4 Alfa glycosidic linkage. It is not easy to digested and takes less space than amylopectin. Amylopectin is branched and consisting 1 alfa 1-6 linkage per 30 alfa 1-6 linkage. It is similar to glycogen expecting lower level of branching.
What is the difference between starch solution and iodine solution?
Starch is composed of amylose and amylopectin, and is not soluble in water due to the presence of amylopectinIodine (I₂) is somewhat soluble in water, but is more soluble in iodide (I⁻) solutions, such as potassium iodide solution (KI).Aqueous iodine molecules (I₂) and iodide ions (I⁻) together will form triiodide ions (I₃⁻), which can react with amylose found in starch to produce a deep-blue colour in the solution. So all of iodide (I⁻), iodine (I₂) and amylose (or starch) are required together to produce the colour.This can be used to test for:Amylose/Starch: Add iodine dissolved in potassium iodide solution to test solution, orIodine: Add starch and potassium iodide solutions to test solution.If the substance being tested for is present, then triiodide ions (I₃⁻) can react with amylose (in starch) to produce a deep-blue colour, that is, a positive result.
How do you distinguish between sugar solution and neem solution with eyes closed?
by tasting it simple
Why is the Benedict's test is positive when water starch and HCl keep for 30mins?
benedicts test is positive when water starch and HCL keep for 30 mins because glycosidic linkages between amylose and amylopectin breaks and free ends are available to react with Benedict reagent
What criteria is used to distinguish between a true solution and collide?
tyndall effect
What does amylopectins do to starch?
Starch is a mixture of two types of polymers (or macromolecules) namely: Amylose and Amylopectin. Both polymers have a fairly large distribution of sizes, but are still made of glucose units. The main distinguishing factor between amylose and amylopectin is the amount of branching. Amylopectin is more branched than amylose (long chain polymer). So amylopectin is actually refering to starch molecules which are branched.
Are starches with a relatively large amount of amylose digested more quickly than those with amylopectin?
Enzymes are often substrate-specific, meaning they will only catalyze a reaction with a certain molecule. The difference in structure between amylose and amylopectin causes amylase to catalyze one and not the other.

What is the difference between amylose and amylopectin?
Amylopectin is easer for enzymes to get around and break it down. Amylose is a long unbranced chain of glucose, it has a cylinder like structure wich makes it compact so its good for storage. Amylopectin is a long branched chain of glucose, its structure is a benifit because enzymes that break glycosidic bonds to break down the moleclue get to it faster. This means glucose is released faster.

Starch is a?
Starch is a polymer consisting of large numbers of alpha-glucose units joined together by glycosidic bonds. It is composed of amylose and amylopectin. In amylose, the glucoe is linked in a linear fashion by 1,4 glycosidic bonds. These bonds cause the chain to coil helically into a more compact shape due to the tetrahedral chemistry of carbon and the bond angles that result. Amylopectin is also compact and has a linear arrangement of glucose linked by 1,4 glycosidic bonds. However, at regular intervals, a 1,6 glycosidic bond forms between two adjacent glucose molecules. These bonds result in the formation of a highly branched structure. Starch has three times more amylopectin than amylose.

In a disaccharide two monosaccharides are joined by what kind of bond?
Junctions between saccharide molecules are called glycoside bonds. This not only includes mono saccharides to form disaccharides but also many to form polysaccharides like amylopectin and amylose found in the starch of plants and glycogen in animals.
Which Criteria used to distinguish between true solution and colloids as no residue is left on filter paper on filtration?
In true solution the molecules of the solute get equally distributed throughout the solvent in the atomic level i.e. at the distance of diameter of an atom. While in colloides the molecules are not mixed in such state. So, using this as a principal to distinguish between colloide & solution. We can centrifuge the two mixtures to distinguish the colooide & solution.
What is the difference between long and short grain rice?
The two main starches in rice are amylose and amylopectin. The grains tend to hold on the their amylose but amylopectin can leave the grain and move into the liquid being used for cooking. Long-grain rice has a lot of amylose and not much amylopectin. Short-grain rice has a good balance of both. So long grain rice will be lighter and fluffy because the grains will not get too sticky. Short grain rice will pour starch into the water it cooks in creating a sticky coating on all the grains which, if properly treated, can be made into an amazing, creamy sauce. Long-grain rices are great for dishes where rice is a base for something or playing second-fiddle to something else. Short-grain rice is superb for dishes where the rice is going to be the star, like a risotto.
