Agar is a red algae and a unique vegetable source protein. Agar
has been used in the Far East for centuries and is referred to as
Agar-Agar. Can be used too make a gelatin with water or fruit
juice.
Agar (agar-agar) can be used as a laxative, a vegetarian gelatin
substitute, a thickener for soups, in jellies, ice cream and other
desserts, as a clarifying agent in brewing, and for sizing paper
and fabrics.
Chemically, agar is a polymer made up of subunits of the sugar
galactose. Agar polysaccharides serve as the primary structural
support for the algae's cell walls.
Agar consists of a mixture of agarose and agaropectin. Agarose is a
linear polymer, made up of the repeating monomeric unit of
agarobiose. Agarobiose is a disaccharide made up of D-galactose and
3,*-anhydro-L-galactopyranose. Its major differences from
carrageenans are the presence of L*3,*-anhydro-α-galactopyranose
rather than D*3,*-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 toe
treatment that converts of any L-galactose**-sulfate to
3,*-anhydro-L-galactose.
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 [**8]. Exterior hydroxyl groups allow aggregation of up to
*0,**0 of these helices to form suprafibers.
Agar is used:
As an impression material in dentistry.
To make salt bridges for use in electrochemistry.
In formicariums as a transparent substitute for sand and a source
of nutrition.
By Kanten Clay Studio as a natural ingredient to form modelling
clay for young children to play with
