2. any of a group of antibacterial antibiotics containing such a ring linked to one or more sugars.

mac·ro·lide

(mak'rō-līd),
A natural lactone with a large ring; usually consisting of 14-20 atoms; macrolides include a class of antibiotics discovered in streptomycetes, for example, erythromycin; macrolides also inhibit protein biosynthesis.

n.
A class of antibiotics that are produced by certain actinomycetes of the genus Streptomyces, are characterized by a large lactone ring linked to one or more sugars, and act by inhibiting protein synthesis.

macrolide

A natural lactone with a large (14–20) carbon ring structure that inhibits protein synthesis; e.g., erythromycin.

mac·ro·lide

(mak'rō-līd)
A natural lactone, with a large ring, usually of 14-20 atoms; several antibiotics, including erythromycin, are macrolides. They inhibit protein biosynthesis.
