What is the Iupac name of lactam?
Lactam: A cyclic amide. Caprolactam (IUPAC name azepan-2-one), a lactam used to manufacture Nylon 6.
What are the different types of lactam?
A lactam is a cyclic amide, which can be found in different forms: ?-lactam (three-atom rings), ?-lactam (four-atom rings), ?-lactam (five-atom rings), ?-lactam (six-atom rings), and ?-lactam (seven-atom rings).
What is the structure of the lactams?
This structure is composed of an enclosed dipeptide formed by the condensation of L-cystein and D-valine, resulting in the ?-lactam ring and in the thiazolidinic ring. The reactive nature of the ?-lactam ring system makes penicillins (penams) and related compounds susceptible to a variety of degradative processes.
MECHANISM OF ACTION
?-Lactam antibiotics are bactericidal agents that interrupt bacterial cell-wall formation as a result of covalent binding to essential penicillin-binding proteins (PBPs), enzymes that are involved in the terminal steps of peptidoglycan cross-linking in both Gram-negative and Gram-positive bacteria.
