How does penicillin work to destroy bacteria?

Penicillin kills bacteria through binding of the beta-lactam ring to DD-transpeptidase, inhibiting its cross-linking activity and preventing new cell wall formation. Without a cell wall, a bacterial cell is vulnerable to outside water and molecular pressures, which causes the cell to quickly die.

Why is penicillin better than other antibiotics?

Penicillin V is an enhancement of the original penicillin discovered and was developed so that it could withstand stomach acid and be able to be taken orally.

Penicillin V potassium is used to treat certain infections caused by bacteria such as pneumonia and other respiratory tract infections, scarlet fever, and ear, skin, gum, mouth, and throat infections.

What type of bacteria is penicillin most effective against?

Gram-negative bacteria have peptidoglycan between membranes. Penicillin works best on gram-positive bacteria by inhibiting peptidoglycan production, making the cells leaky and fragile. The cells burst open and are much easier for the immune system to break down, which helps the sick person heal more quickly.

How long does it take for penicillin to work?
