Are Polyols Laxative?
Polyols are laxative.
Are polyols the same as vinyl polymers?
No they are not. Polyols are polyalcohols. Vinyl polymers are polymers of monomers of the type CH2=CHX .
What products of pharmaceutical importance are obtained from corn?
glucose, starch and polyols

What is an alditol?
An alditol is any of a class of acyclic polyols formally derived from an aldose by reduction of a carbonyl functional group.

What kind of atom forms the backbone of monomer and a polymer?
The Carbon atom usually forms the backbone of polymers and quite often oxygen can do also as in polyether polyols etc.
What are the main polymers in gorilla glue?
Gorilla Glue is an unreacted polyurethane. There are diisocyanates and polyether polyols in it, and a chemical that only needs a little water to make the two bond together.
Why does sugar free jello melt faster than sugar jello?
It can be attributed to a number of factors: differing water temperatures (the hotter the liquid, the faster the "melting"), or the fact that the main sweetener used to replace sugar, aspartame, is considered a polyol. A polyol (or sugar alcohol) is derived from natural sugar (glucose), and are just "chopped down" versions of glucose. Polyols are smaller in molecular size than a regular glucose molecule. Simple chemistry notes the smaller the molecule, the faster it will be broken down in the presence of heat or enzymes. Furthermore, products with these sugar derivatives, while being made from actual sugar, can still be labeled as sugar-free, since polyols are not sugars..they are smaller sugar byproducts often with an alcohol group (CH2OH) attached. Because polyols are not found in nature, the body has no enzyme(s) to break down these molecular structures..therefore polyols are very low in calories because it passes through the digestive system unabsorbed. Keep in mind that the more sugar-free products are consumed, the greater the risk is for intestinal distress (bloating, cramping, diarrhea) due to their nonabsorbtion.
How are alcohols different from hydrocarbons?
They've got an oxygen atom between the carbon backbone (or atom, in the case of methanol) and a hydrogen atom at one or more points. This pair of atoms, an oxygen and a hydrogen, is called a hydroxyl group. There are a LOT of different alcohols. Some have only one hydroxyl group. These are the monohydric alcohols, of which there are three: methanol, ethanol and isopropanol. Some have two, and these are the diols. The glycols are diols. Alcohols with three hydroxyl groups are triols. Glycerol is a triol. The final group are the polyols, which have more than three hydroxyls - in most cases thousands of them. Most polyols are used to make plastic.
