Summary Introduction

To analyze:

The organic molecules are considered as the molecules of life.

Introduction:

Chemistry is the branch of science which studies the matter, interaction forces and the ways in which matter changes its state. There are three parts of chemistry organic, inorganic, and physical chemistry.

Organic chemistry deals with carbon and its compounds. Life is based on carbon or we can say that carbon is the backbone of the organic molecules which forms life.

The atomic number of carbon is 6. Its electronic configuration (E.C) is

$\begin{matrix} C = 6 \\ E . C = 1 s^{2} 2 s^{2} 2 p^{2} \\ E . C = \begin{matrix} 1 s & 2 s & 2 p_{x} & 2 p_{y} & 2 p_{z} \\ ↑ ↓ & ↑ ↓ & ↑ & ↑ & - \end{matrix} \end{matrix}$

According to the octet rule, carbon has to attain a noble gas configuration of Neon (Ne) which is 8. So, to complete its outer shell electrons, carbon has to gain 4 electrons, lose 4 electrons or share electrons. Hence, to complete its octet, carbon only shares electrons and forms covalent bonds.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
