    Agar or agar agar is a substance derived from . Historically and in a modern context, it is chiefly used as an ingredient in desserts throughout , but in the past century has found extensive use as a solid to contain for work. The gelling agent is an unbranched obtained from the of some species of , primarily from the and , or (Sphaerococcus euchema). Commercially it is derived primarily from .

    Agar (agar agar) can be used as a , a substitute, a thickener for , in , and desserts such as , as a clarifying agent in , and for fabrics.

    Chemically, agar is a made up of subunits of the sugar . Agar serve as the primary structural support for the algae's cell walls.

    Structural Unit

    Agar consists of a mixture of agarose and agaropectin. Agarose is a linear polymer, of molecular weight about 120,000, based on the -(1->3)-β-D-galactopyranose-(1->4)-3,6-anhydro-α-L-galactopyranose unit, the major differences from carrageenans being the presence of L-3,6-anhydro-α-galactopyranose rather than D-3,6-anhydro-α-galactopyranose units and the lack of sulfate groups. Agaropectin is a heterogeneous mixture of smaller molecules that occur in lesser amounts. Their structures are similar but slightly branched and sulfated, and they may have methyl and pyruvic acid ketal substituents. They gel poorly and may be simply removed from the excellent gelling agarose molecules by using their charge. The quality of agar is improved by alkaline treatment that converts of any L-galactose-6-sulfate to 3,6-anhydro-L-galactose.

    [] Molecular structure

    Agarose molecules have molecular weights of about 120,000. The gel network of agarose contains double helices formed from left-handed threefold helices. These double helices are stabilized by the presence of water molecules bound inside the double helical cavity [508]. Exterior hydroxyl groups allow aggregation of up to 10,000 of these helices to form suprafibers.
