What is Biochemistry? - Biochemistry is the study of the chemical substances and vital processes occurring in live organisms. Biochemistry is the study of all the life processes within a living organism
Clearly, the qualities of chemical structure information and experimental endpoints, as well as the statistical parameters used to verify the external predictivity have a strong influence on QSAR model reliability. Here, we emphasize the importance of these three aspects by analyzing our models on ...
