Natural enzymes are remarkable molecular machines that enable all sorts of essential biochemical reactions. For decades, ...

The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Non-Essential Amino Acids: These amino acids can be synthesized ...

These eight random poly(AC) RNAs produced proteins containing only six amino acids: asparagine, glutamine, histidine, lysine, proline, and threonine. Remember that previous experiments had already ...

Our procedure alters the order of emergence of certain amino-acids from the column ... of a small unidentified peak between lysine and histidine. 1-Methyl histidine, 3-methyl histidine and ...
