Agar consists of a mixture of agarose and agaropectin.Its major differences from carrageenans are the presence of L-3,6-anhydro-α-galactopyranose rather than D-3,6-anhydro-α-galactopyranose units and the lack of sulfate groups.Agar is used throughout the world to provide a solid surface containing medium for the growth of bacteria and food additives. Many specific formulations are available, because some microbes prefer certain environmental conditions over others.
As a concentration gradient develops from the thickener of the chemoattractant into the gel, various cell populations requiring different stimulation levels to migrate can then be visualized over time using microphotography as they tunnel upward through the gel against gravity along the gradient.Agar is a heterogeneous mixture of two classes of polysaccharide: agaropectin and agarose.Although both polysaccharide classes share the same galactose-based backbone, agaropectin is heavily modified with acidic side-groups, such as sulfate and pyruvate.
Agar-agar is approximately 80% fiber, so it can serve as an intestinal regulator.This results in the consumer feeling more full. Recently this diet has received some press coverage in the United States as well. The diet has shown promise in obesity studies.
