Formic acid, systematically named methanoic acid, is the simplest carboxylic acid.The chemical formula is .The chemical composition is H COOH.It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. The word "formic" comes from the Latin word for ant, formica, referring to its early isolation by the distillation of ant bodies.
The cyclic dicarboxylic anhydride that is the anhydride of phthalic acid. ChEBI CHEBI:36605
May 22, 2014· Functional groups are the groups of atoms that are attached to the carbon backbone of organic molecules. Functional groups are responsible for the characteristic chemical reactions of organic compounds. They are less stable than the carbon backbone and are more likely to take part in chemical reactions. They determine the characteristics and chemical reactivity of organic molecules.
In this review we intend to provide a relatively comprehensive summary of the work of supramolecular hydrogelators after 2004 and to put emphasis particularly on the applications of supramolecular hydrogels/hydrogelators as molecular biomaterials. After a brief introduction of methods for generating supramolecular hydrogels, we discuss supramolecular hydrogelators on the basis of their .
