Description

Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

agar : A complex mixture of polysaccharides extracted from species of red algae. Its two main components are agarose and agaropectin. Agarose is the component responsible for the high-strength gelling properties of agar, while agaropectin provides the viscous properties.
