Detailed explanation-1: -Agar agar is a product obtained from numerous algae, mainly of the genus Gracilaria, Gelidium and Eucheuma. All of these algae are characterized by belonging to the group of red algae. These algae are small, have a reddish stem and are rich in mucilage, a type of fiber.

Detailed explanation-2: -agar, also called agar-agar, gelatin-like product made primarily from the red algae Gelidium and Gracilaria (division Rhodophyta).

Detailed explanation-3: -Agar-agar is a gelling agent with unbranched polysaccharides and is used in microbiology as a solidifying agent of liquid culture mediums. It is extracted from the cell wall of red algae, mostly from Gelidium sp. and Gracilaria sp.

Detailed explanation-4: -No worries! We’ve got your back.

Detailed explanation-5: -The gelling agent in agar is an unbranched polysaccharide obtained from the cell walls of some species of red algae, primarily from the genera Gelidium and Gracilaria. For commercial purposes, it is derived primarily from Gelidium amansii. In chemical terms, agar is a polymer made up of subunits of the sugar galactose.
