User talk:Ahmed khan rocks

January 2017
Hello, I'm Marianna251. I noticed that you made a change to an article, Hexose, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Marianna251TALK 17:30, 20 January 2017 (UTC)
