Polylysine and polyglutamate are two examples of synthetic polypeptides which can assume an α-helical structure under appropriate conditions. identify which of these two synthetic polypeptides can form an α-helix at the indicated ph values.

Lys is an amino acid that has a side chain with a positive charge, so it will likely form an alpha helix in basic conditions while glutamate is acidic so it will likely form an alpha helix in acidic conditions.

Polylysine @ pH13

Polyglutamate @ pH 2

a polar bond is formed when electrons are shared unevenly between atoms

the answer would be a
