Document Summary
Question 1 draw two amino acids sitting side by side unbonded, then draw them with a peptide bond connecting them. Two amino acids connect through a dehydration reaction resulting in a peptide bond between them and a water molecule. Why is its classification a bit ambiguous (it is sometimes classified as non-polar)? (hint: discuss the chemistry of the r group) Tyrosine is a polar amino acid because the r-group contains an. Oh group that allows it to participate in hydrogen bondings. Its classification is a bit ambiguous because the r-group has both polar and non-polar characteristics: draw another amino acid. Say something about the chemistry of its r group (categorization, types of interactions it would make in different levels of structure, etc). This is a structure of alanine, a non-polar (hydrophobic) amino acid. The r group will not do much in primary structures since only the backbone is connected by peptide bonds.
