5. Penicillin is an antibiotic that prevents bacterial cell wall growth by inhibiting a single enzyme found in many bacteria. This discovery greatly transformed human health, empowering a drastic increase in human life expectancy by ~25 years from 1928 to 1950. Please answer the following questions regarding penicillin. The skeletal formula structure for penicillin is found below. IN H H SCH$_3$ N CH$_3$ OH #sp2 carbons Chemical Formula i) In the structure above, please circle all sp3 carbon stereocenters. Please indicate whether each one is the 'R' or the 'S' stereochemistry next to the circle you drew. ii) In the structure above, please put lone pairs of electrons on any atom to fulfill the octet rule. iii) In the structure above, how many sp2 carbons are present? Please write the number in the box above. iv) Please name the specific types of carbonyl functional groups next to the carbonyl above. v) What is the chemical formula for the molecule drawn above? Please write it in the box above. vi) Name the specific functional groups that contain a carbonyl in the structure above. vii) At physiological pH (pH=7.6), would this molecule be in a zwitterionic form? Please circle YES / NO
