Just looking for some good references on amino acids with some totals to give me a idea of the big picture
How many amino acids are formed by DNA (19,20,21,22,23) need list with proline (although its NOT one) How many amino acids exist in nature (approx number with a good reference link) How many amino acids have been found in life (approx number with good reference link) How many amino acids have been found in human proteins (approx number with good reference link)
Also, if possible as proline is not an amino acids but its in all the lists, are their other DNA combinations (3 char goups) that are considered important or possibly important and are common in human proteins.
Any and all help is greatly appreciated, already spent a good amount of hours trying to find good sources, so if you can even give me 1 or 2 of the answers that's great!
Tom
