Question

Which of the following is a beta-lactam antibiotic?

• A. Vancomycin
• B. Amoxicillin
• C. Erythromycin
• D. Doxycycline

Hint:

Beta-lactams include penicillins, cephalosporins, carbapenems, and monobactams.

Answer 1

The Correct Option is B

A beta-lactam antibiotic is characterized by the presence of a beta-lactam ring in its molecular structure. This class of antibiotics functions by inhibiting the synthesis of bacterial cell walls, leading to the destruction of the bacteria.

Let's analyze each option:

• Vancomycin: This is a glycopeptide antibiotic, not a beta-lactam.
• Amoxicillin: A penicillin-type antibiotic that contains a beta-lactam ring, making it a beta-lactam antibiotic.
• Erythromycin: This is a macrolide antibiotic, which does not contain a beta-lactam ring.
• Doxycycline: A tetracycline antibiotic, also lacking a beta-lactam ring.

Therefore, the correct answer is: Amoxicillin
