So what this tissue factor does is it's actually a glycoprotein that basically interacts with other molecules, namely factor seven, to form a dimer complex. And this glycoprotein, this tissue fact, is actually used to initiate the blood clot and cascade, the formation of the blood clot. More specifically, it initiates the extrinsic pathway of that coagulation cascade. And we have many, many, many different types of examples of ways in which we can actually modify proteins as well as lipids and thereby diversify their function, thereby increase their capabilities and functionality. Now, the final thing I'd like to mention about sugar molecules is that in plants as well as in bacterial cells, sugars actually make up. The components, are components of cell walls.
