While the 20 natural amino acids have existed on Earth for
billions of years, Chemists have been able to synthesize
unnatural amino acids. For instance, scientists recently created an
amino acid that resembles Lysine but the primary amino group on
the side-chain now has a pk, value close to 14. A polymer of this
unnatural Lys amino acid is formed and tested for a-helix
formation at different pH values. You predict that the helix will
form only at:
swered
• pH values well below (e. g. lower) 14
pH values well below (e. g. lower) 10
Answer
pH values well above (e. g. higher) 14
physiological pH
physiological pH
pH values well above (e. g. higher) 10
