The area of A. Kompaniets’s scientific interest is the investigation of homological series of chemical compounds — polyols, amides and their derivatives, products of the directed synthesis; the ascertainment the type of a relation between cryoprotective activity, cytotoxicity, compound toxicity, structure and physicochemical properties. She realizes in her work one of the ways of creation and obtaining of new cryoprotectors — chemical modification of the known compounds. Research areas linked to phase transition and development of methods allowing to direct it, so that it is possible to optimize the technology of
