Abstract: The course of biochemistry for undergraduate was the key basic course of biological field and other relevant fields. The present paper gave some suggestions about the contents in the last class including that the life consisted of complicated bio-macro-molecules and small molecules based on the ordinary organic molecules, the high grade structure of bio-macro-molecules relied on its low grade structure, the helix structure was the main motif of bio-macro-molecules, the natural instincts of bio-macro-molecules were the power to construct its high grade structure, and consequently gave the self-organization characteristics inter molecules and the dissipative characteristics for life. The complicated structure level of bio-molecule decided its complicated level of functions, the complex of bio-super-molecules was the main form while functioning, the functioning process of bio-molecules was the interaction or recognition among the molecules, and the results from the interaction and life process obeyed the "butterfly effect". At present, the characteristic of life was elucidated with using the knowledge of molecular biology.

Key words: biochemistry, helix structure, bio-super-molecular, function corresponding to the structure, bio-molecule recognition
