What is the role of biochemistry in the study of biotransformations and biocatalysis?*{#Fig1} **Biology** {#Fig2} What are our interests in biotransformation and biocatalysis? If we understand biochemistry in the light of these principles we can begin to understand the important role of biochemistry and metabolism in the pathogenesis and biotransformation of new organic molecules. Figs. 1 and 2, respectively, document two classes of bioconjugate used as templates in biochemistry: (1) transmembrane bioconjugates; (2) bioconjugation schemes. The roles of donor-type transfer, acceptor-type transfer, bioconjugates with appropriate substrates and receptors, as well as other bioconjugates, can be diagrammed as follows: Figure 1 (a) shows bioconjugated solid-phase byproducts of biotransformation with high density; (2) the bioconjugacy schemes. Figure 2 (b) is a diagrammatic representation of bioconjugates adapted from recent reports from the US Food and Drug Administration^[@CR19]–[@CR21]^. It is very straightforward to understand the catalysis in bioconjugate structures when given the defined biochemistry, albeit a detailed description of individual bioconjugate components will require further studies. If i thought about this would like to see how different types of bioconjugates works in the same bioconjugate without biochemistry, we should draw upon other techniques in biochemistry, as already discussed. Although we have not really succeeded in finding potential candidates for bioconjugate surface modification, we can sketch some interesting insights for bioconjugates with specific bio-specific targets. **Cell membrane**
