Detailed explanation-3: -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.

Detailed explanation-4: -Most agar is extracted from species of Gelidium (Figure 1) and Gracilaria (Figure 2). Closely related to Gelidium are species of Pterocladia, and small quantities of these are collected, mainly in the Azores (Portugal) and New Zealand. Gelidiella acerosa is the main source of agar in India.
