Re: BUILDING BLOCKS
About this: Letters are the building blocks of words and, ultimately, language. Similarly, amino acids are the building blocks of proteins and, ultimately, life. Each amino acid has one (2 in some cases) single letter as its designation. All letters of the alphabet are used except for X. X is meant to denote any amino acid. Each amino acid in the design is shown associated with its single-letter abbreviation. For fellow geeks, I assigned an alanine to X, O is Pyrrolelysine and U for Selenocysteine. I know, really obscure but I needed them. Unfortunately, the design looks much better in PS than on this site. I just submitted a blue design that turned out a bit better.
