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

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
