Question

For each pair of amino acids, draw the structures of the amino acids and show the strongest interaction that they could have VIA THEIR SIDE CHAINS. Qualifiers in parentheses refer to side chains. Use Table 4-1 in VVP. The side chains are indicated with red. 4. 1 lysine (charged form) 2 threonine 3 phenylalanine aspartic acid (charged form) asparagine methionine 4 aspartic acid (charged form)tyrosine 5 histidine (neutral form) histidine (charged form) Rank these five interactions from strongest to weakest. Some may be similar, these do not have to be distinguished.

Explanation / Answer

Interactions -

Lysine & aspartic acid - Ionic Interactions ( strongest)

Threonine & asparginine - dipole - dipole interactions

Aspartic acid & tyrosine - dipole -- dipole interactions

Histidine neutral & histidine charged - dipole - induced dipole interaction

Phenylalanine & metheonine - Vander wall interactions (weakest )
