Highly methylated agars with a high gel-melting point from the red seaweed, Gracilaria eucheumoides.

Highly methylated agars were isolated from the red seaweed, Gracilaria eucheumoides, harvested in Japan. One of the obtained agars formed a thermo-reversible gel with a high melting point up to 121 degrees and was indicated to consist of a regularly repeating structure,-->3 6-O-methyl-beta-D-Gal(1-->4) 3,6-anhydro-2-O-methyl-alpha-L-Gal 1-->.
