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.
Next. toluene is an aromatic with a CH3 attached at the top a catalyst is needed for this reaction to occur (i think) and i'm pretty sure it has to be FeCl3.. but i'm not sure. the equation i need should have the shape of toluene (hexagon with a circle in the middle) + Br2 --(the catalyst is FeCl3 i...show more.est Answer: When you react toluene with Br2 in the presence of FeBr3 catalyst, you will get a mixture of 2-bromotoluene and 4-bromotoluene. The CH3 group is a ortho-and para-directing activator for electrophilic substitution on the benzene ring. Source(s): tfizzum4 Â· 7 years ago.
