Using the abv percentage, I'd figure out the cost of three ounces of straight alcohol. Then, based on the price per ounce of each type of booze, I'd figure out the cheapest ways to get the most alcohol. So the formula is... See, kids -- the stuff you're learning in math class does come up in real life.
Lignin. Definition. noun. An organic substance that acts as a binder for the cellulose fibers in certain plants adding strength and stiffness to the cell walls. Supplement. Lignin is an organic substance belonging to a group of aromatic alcohols. It is naturally produced by certain plants (especially woody plants and certain algal species).
The chemical composition of lignin has not been conclusively established. The lignin molecule consists of the products of polymerization of aromatic alcohols, and the basic monomer is coniferyl alcohol: Lignin is an amorphous substance, yellowish brown in color; it is insoluble in water and organic solvents. It is stained by basic dyes and yields color reactions characteristic of phenols. The biosynthesis of lignin has not been completely studied.
