Abstract:
Objective To study the molecular recognition of porphyrin compounds with carbohydrate molecular. Methods Fluorescent titration method was developed to explore the porphyrin and its metal porphyrin compounds interaction with carbohydrate compounds. Results The binding constants indicated that porphyrin and its metal compounds involved in this experiment could recognize carbohydrate compounds respectively, and interaction with lactose is stronger than glucose; Comparison with free porphyrin, metal ion Zn~(2+) and Fe~(3+) in the core of porphyrin compounds could enhance the binding capability with carbohydrate. Conclusion Porphyrin compounds has selective molecular recognition abilityto sugar molecular.
