1. a chemical compound characterized by a large lactone ring containing multiple keto and hydroxyl groups.
2. any of a group of antibacterial antibiotics containing such a ring linked to one or more sugars.
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.
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.
macrolideA natural lactone with a large (14–20) carbon ring structure that inhibits protein synthesis; e.g., erythromycin.
A natural lactone, with a large ring, usually of 14-20 atoms; several antibiotics, including erythromycin, are macrolides. They inhibit protein biosynthesis.
