Why can the complex sugars cellulose store more energy than the sugar glucose?
Cellulose has more chemical bonds.
What do hydrophobic molecules avoid?
Hydrophobic molecules avoid water. Strictly speaking, they do not attract water, and therefore water will avoid them, since it is more attracted to other molecules or to itself.
What molecules form cellulose which gives structure?
Cellulose is a polymere of �-1,4 glucosidical bonded glucose units (more than 1000).
Why are synthetic materials made?
Because you can design a synthetic polymer to exactly meet your needs. You can modify a natural polymer sometimes if it's not what you need, but at that point is it really a "natural" polymer? Take cellulose--a perfectly serviceable natural polymer, they build millions of homes every year out of it. But what if you need a polymer you can see through? Cellulose won't work for you there unless you dissolve it in acetic acid (cellulose acetate) or nitric acid (cellulose nitrate). By the time you're done, you have a polymer that's no longer really "natural."
What natural monomer contains 3000 or more glucose monomers?
Cellulose
Is cellulose acetate a plastic?
Cellulose is one of many polymers found in nature. Wood, paper, and cotton all contain cellulose. Cellulose is an excellent fiber. Wood, cotton, and hemp rope are all made of fibrous cellulose. Cellulose is made of repeat units of the monomer glucose. This is the same glucose which your body metabolizes in order to live, but you can't digest it in the form of cellulose. Because cellulose is built out of a sugar monomer, it is called a polysaccharide.Cellulose acetate was first prepared by Paul Schützenberger in 1865. Commercially, cellulose acetate is made from processed wood pulp. Cellulose acetate fibres are used for textiles and clothing by many of the top designers in the world. Early frames for spectacles were cut from sheets of cellulose acetate. While use of cellulose acetate has largely been superseded by injection moulding with more modern thermoplastics, some up-market spectacles are still made in this way.
Who invented cellulose acetate?
No-one invented this product exactly. Paul Schützenberger discovered it in 1865. Subsequently others found ways of dissolving it and otherwise processing it so that it would be commercially and industrially valuable. Please see the cellulose acetate article of wikipedia for more information.
What material is used to make x-ray film base?
the first ever base was the cellulose nitrate but it flammable that contribute to the severe hospital fires during 1920's. it was then replaced by the cellulose triacetate which was not as flammable as cellulose nitrate. in the early 1960's it base was introduced. it is more resistant to warping and is stronger than the two other bases.
Is epsom salt the same as aluminum acetate?
No, epsom salt, which is magnesium sulfate, or MgSO4 that is hydrated (MgSO4·7H2O), is chemically different from aluminum acetate. The latter has several forms, including aluminum monoacetate, (HO)2AlC2H3O2, aluminum diacetate, HOAl(C2H3O2)2, and aluminum triacetate, Al(C2H3O2)3.

Solubility of ethyl cellulose?
Practically insoluble in water, in glycerol, and in propane-1,2-diol, but soluble in varying proportions in certain organic solvents, depending upon the ethoxyl content. Ethyl cellulose containing less than 46-48% of ethoxyl groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform, and in aromatic hydrocarbon ethanol mixtures. Ethylcellulose containing 46- 48% or more of ethoxyl groups is freely soluble in ethanol, in methanol, in toluene, in chloroform, and in ethyl acetate.
What is the difference between ethyl acetate and n propyl acetate?
Propyl acetate has one more carbon atom.
Is silica more polar than ethyl acetate?
Yes silica is more polar then ethyl acetate . Deepak
Who has more hydrogen atoms hydroxide or acetate?
Hydroxide is OH. Acetate is C2H3O2. So Acetate has three while Hydroxide has one.
What is chaotropic salt?
A chaotropic salt is a salt that disrupts stabilizing intra-molecular forces such as hydrogen bonding. They the structures of biomolecules as proteins and nucleic acids. It will make hydrophobic proteins more soluble in water. Examples: magnesium chloride, lithium acetate, lithium perchlorate.
Why can more complex suger cellulose store more energy than the sugar glucose?
