Harlamova29_29 [7]

Pulse pressure or PP is the difference between the top or higher number (systolic) and the bottom number (diastolic) blood pressure. Pulse pressure can find out by the systolic minus the diastolic of Blood pressure.

For example, if an individual's resting BP is 120/80 millimeters of mercury (mm Hg), the normal PP is 40 which is considered a healthy pulse pressure. So, as per the normal BP 120/80, if the pp was 32 than the bp would be 120/88 or 112/80.

Other components as alpha carbon ( C ), carboxyl group ( COOH ) and amino group ( NH2 ) is fixed for every amino acid.
