Updated example

Earlier today I noted that 2-pentanol (Q210479) was used as an example. However, that entity is not stereochemically pure compound, but rather a mixture of the two (or the concept of the 2-propanol with undefined stereochemistry). See the Wikipedia entry and the description in Wikidata. So, I had removed the isomeric SMILES, only to be pinged by Pigsonthewing (talk • contribs • logs) that it was the example here. Therefore, I decided to update the example. It now uses L-alanine (Q218642).
