Why can the complex sugars cellulose store more energy than the sugar glucose?
Cellulose has more chemical bonds.
How does the derivatization of cellulose alter its physical properties?
Derivatization of cellulose involves chemically modifying its hydroxyl groups, which can significantly alter its physical properties. This process can improve solubility, thermal stability, and mechanical strength, making cellulose more versatile for various applications. For instance, introducing hydrophobic groups can enhance water resistance, while forming esters or ethers can increase flexibility and reduce brittleness. Overall, these modifications enable tailored materials with specific performance characteristics for industrial and biomedical uses.
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.
Is hydrophobic unsaturated?
Hydrophobic refers to molecules that repel water, while unsaturated refers to molecules that contain one or more double bonds in their structure. These terms are not directly related, as a molecule can be either hydrophobic or hydrophilic regardless of its saturation level. However, many hydrophobic molecules tend to be nonpolar and contain a higher proportion of saturated bonds.
What molecules form cellulose which gives structure?
Cellulose is a polymere of �-1,4 glucosidical bonded glucose units (more than 1000).
What is the difference between viscose and cellulose acetate?
Viscose is a type of rayon made from regenerated cellulose, while cellulose acetate is a synthetic fiber made from wood pulp or cotton fibers chemically treated with acetic acid. Viscose tends to be more breathable and drapes well, while cellulose acetate is more resistant to shrinking and wrinkling.
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.
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.
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.
Is a hydrophobic molecule more likely to be polar or nonpolar?
A hydrophobic molecule is more likely to be nonpolar.
Who has more hydrogen atoms hydroxide or acetate?
Hydroxide is OH. Acetate is C2H3O2. So Acetate has three while Hydroxide has one.
Is silica more polar than ethyl acetate?
Yes silica is more polar then ethyl acetate . Deepak
Why can the complex cellulose store more energy than the sugar glucose?
Cellulose has more chemical bonds.
Why can sugar cellulose store more energy than the sugar glucose?
Cellulose has more chemical bonds.
Is ethyl acetate more polar than toluene?
Yes, ethyl acetate is more polar than toluene.
