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

Explain why soluble starch does not conduct electricity?

Starch is an chain of sugar molecules, and the chain separates to its individual sugars when dissolved. Because sugars are made of C, H, and O, there are no metals and no ionic bonds in the molecule, so it does not conduct electricity when dissolved in water.


Do isomers boiling points increase or decrease with more branching?

Straight chain isomers have higher boiling points, so the more branched the isomer the lower the boiling point.


What molecule is larger starch or sugar?

Starch is a storage polysaccharide and is therefore much larger than sugar, which is merely carbohydrate molecules. Starch is composed of long chains of glucose monomers linked to one another through different types of linkages. Starch shows a branched structure composed of two components: amylose and amylopectin, both of which are basically chains of glucose units. They way in which they are linked to one another decides their properties.


How many reducing ends are in a molecule of glycogen that contains 10000 residues with a branch every 10 residues?

The question cannot be answered unambigously based on the information given, since the number depends on how long the chains at each branching point are. If there is one glucose substituent per branching point, the no. of glucose molecules used for the substitution is found by iteration starting by 60000/12 = 5000, but 55000/12 = 4583. Hence the average is where the ends meet: That is about 4791 substituents (depending on how numbers are rounded up or down), which gives 4791 non-reducing ends + 1 from the "backbone = 4792. If there are two glucose substituents per branching point, the no. of branching points, and hence the no. of reducing ends will decrease to about a little less than half of this number because more glucose monomers are "consumed" in the branching chains and the backbone chain will in turn be shorter resulting in fewer possible branching points. However, each branching chain will only have one non-reducing end, and the backbone will stil have only one non-reducing end! :-) Nice question though - I can add that if there is only one large molecule containing all these 60000 glucose monomers there will be only one reducing end no matter how many branching points there are.

Why does viscosity go on increasing with increasing chain length of straight-chain alkanes but for isomeric alkanes viscosity increase with branching?

Viscosity increases with increasing chain length of straight-chain alkanes while that for isomeric alkanes increase with branching because of the difference in the number of rings contained within their hydrocarbons.


Does a molecule of starch have more stored energy than a glucose molecule and why?

yes - starch is a larger molecule (with more bonds holding atoms together, so it has more energy) because it is a polymer of glucose. Glucose is one ring of carbons and starch is a chain of these.


Does cellulose have branched chains?

Cellulose is a polymer of 3000-5000 non-branched molecules of glucose.


How does boiling and melting points vary as branching in a hydrocarbon chain increase?

As branching increases, the size of the molecule is more (when compared to its unbranched isomer). Hence there are more number of molecules per unit area / volume. Hence the melting point increases, as branching increases.


What is the simplest form of starch?

The two components of starch are amylose and amylopectin. Amylose is a straight chain molecule made of glucose molecules joined by alpha 1-4 links. Amylopectin is a branched molecule made of glucose joined by alpha 1-4 links, with branches joined by alpha 1-6 links.


Is it true that cellulose is composed of beta glucose molecules and starch is composed of a chain of alpha glucose molecule?

True.


What monosaccharides make up glycogen and starch?

Sucrose is a disaccharide made of glucose and fructose. Starch is a polysaccharide that is simply a chain of glucose.

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.....


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


Do isomers boiling points increase or decrease with more branching?

Straight chain isomers have higher boiling points, so the more branched the isomer the lower the boiling point.
