Özet

Antifreeze proteins (AFP) were first discovered by De Vries et al. in blood plasmas of Antarctic fish (Notohenioides). Antifreeze proteins show a great diversity in their structure, and they are identified in a variety of organisms including bacteria, insects, plants and fish. They are glycopeptide structures formed by the attachment of a third amino acid disaccharide molecule of a three amino acid peptide chain and their repetition (Ala-Ala-Thr-galactosyl-N-acetyl galactosamine). Antifreeze proteins have special relevance to ice crystals. Because of this interest Antifreeze proteins have the ability to bind ice crystals and control the growth and recrystallization of ice crystals. AFPs are very important in preserving quality and texture by keeping the heat away from frost. These special proteins, which have important functional properties for the food industry, are now being used effectively in the medical, food and industrial fields.
