Answer from: jaelynnm

The biological function of penicillin primarily stems from the reactivity of the cyclic amide functional group also known as the β-lactam ring from the penicillin molecular structure. Attached is an image of the penicillin molecule and in red is the ring. This ring is the reactive portion because it has the ability to binding to the enzyme DD-transpeptidase, blocking it. This enzyme is important because it is involved in the synthesis of the bacterial cell wall.

Answer from: ana9340

The biological function of penicillin stems primarily from the reactivity of β-lactam ring (cyclic amide) functional group.

β-Lactam Ring:

It is the most important part of the penicillin structure. It is a cyclic amide functional group. This ring bind with enzyme DD-transpeptidase and block its function.The enzyme DD-transpeptidase is involed in bacterial cell wall synthesis.

Hence, we can conclude that the biological function of penicillin stems primarily from the reactivity of β-lactam ring (cyclic amide) functional group.

Answer from: Quest

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a 1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by 1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
