What is in an agar mixture and what is it?

Answer 1

Agar is a sulfated heteropolysaccharide obtained from certain marine red algae. The two major components of agar are the unbranched polymer agarobiose and a branched component agaropectin. It has a remarkable gel forming property and is metabolically inert. It solidifies at 45oC.
It is mainly used as a solidifying agent in microbiological media to support the growth of bacterial colonies. Another commercial use of agar is for the capsules in which some vitamins and drugs are packaged.
The agar without agaropectin (because it interferes current conduction) is called agarose which is used as inert supports for the electrophoretic separation of nucleic acids.
