Agar

Agar, also known as agar-agar, is a gelatinous polysaccharide derived from the cell walls of certain species of red algae, primarily those belonging to the genera *Gelidium* and *Gracilaria*. It is a gelling agent, thickening agent, and stabilizer widely used in various applications. agar is a complex carbohydrate, composed primarily of agarose and agaropectin. It is valued for its ability to solidify solutions, creating a firm, yet pliable gel, even at low concentrations, and its resistance to microbial degradation makes it useful for many applications.
