Amino Acid Reference

A great resource to check amino acid property and structure The program is feature rich and easy to use                 Decent App

This is a useful application for reviewing the essential properties of amino acids allowing you to quickly group them by pH polarity etc The main page is puzzling in that the amino acids are colored differently yellow blue pink and teal but it is unclear what this color coding represents When you sort the amino acids by a property such as pH the acidic ones are identified by a red frame the basic ones by a blue frame Because of the above coloring system it is actually hard a times to see the frames It would have been better to have the entire icon change color as needed Another shorting coming is that one cannot use the single letter code to identify amino acids Thus if you cant remember what the letter W symbolizes for example you need to scroll through all the members It would have been better if one could retrieve amino acid names by the single symbol system A third problem is that it does not appear possible to contact the developer Ive tried Notwithstanding these limitations this is a pretty good program containing more information that the only other amino acid program currently available through the App store           A good start but could be improved
