Infobox references. Tryptophan (abbreviated as Trp or W; encoded by the codon UGG) is an Î±-amino acid that is used in the biosynthesis of proteins. It contains an Î±-amino group, an Î±-carboxylic acid group, and a side chain indole, classifying it as a non-polar, aromatic amino acid.
toluene is a common name-The IUPAC name for toluene is methylbenzene.he use of this trivial form (acetate for ethanoic acid in general) is so common that this is called a retained IUPAC name.
Best Answer: Because toluene is strongly nonpolar: NaCl (strongly polar salt) will ~not~ dissolve. I2 (nonpolar molecule) ~will~ dissolve. Toluene is ~not~ miscible in water (polar solvent). Substitute toluene for carbon tetrachloride (they're both nonpolar solvents) in the link below for a more thorough discussion. Source(s): http://dl.clackamas.edu/ch105-03/example...
