Question

The amino acid methionine is biosynthesized by a multistep route that includes reaction of an imine of pyridoxal phosphate (PLP) to give an unsaturated imine, which then reacts with cysteine. What kinds of reactions are occurring in the two steps?

What amino acid is formed when CH$_3$CONHCH(CO$_2$Et)$_2$ is treated with the following series of reagents: [1] NaOEt; [2] CH$_2 =$ O; [3) H$_3$O$^+$, $\triangle$?

Okay, I am going to talk about the importance of assisting on a proteins tertiary structure. Now, the tertiary structure, remember, is more about three D structure. So for Sistine, Sistine acts two stabilized. So Sistine offers stability. Now we can have to file groups. Well, put two in parentheses from 15 to form this guy sulfide linkage. Now what these dio is they fastened to parts? So this is where that stability comes from fastened to parts. And this is the importance of sustained and the tertiary structure of a protein.

In this problem. We're looking for the Alfa Keto acid that is produced from Trans Am a nation. Our first reaction takes place between glycerine and Alfa Kato glued rate in trans emanation reactions. We see an exchange of this group on the amino acid and this oxygen here. When we do this exchange and we predict our products, we find that we get a new Alfa Keto acid here and a new amino acid. And this Alfa Keto acid is our product that we're interested in. We can repeat the same procedure now with Valentin and Alfa Kyoto glued a rate. When we do this exchange and predict our products, we get the Alfa Keto acid that we're interested in, and we also get a new amino acid.

In this problem. We're looking for the Alfa Keto acid that is produced from Trans Am a nation. Our first reaction takes place between glycerine and alpha keto, glittery in trans am. In ation reactions, we see an exchange of this group here on the amino acid and this oxygen here on the Alfa Kita Glittery. When we do this exchange and predict our products, we find that we get a new Alfa Keto acid here and we get a new amino acid here. And this new Alfa Keto acid is what we're interested in as our product. And finally answer, we can repeat the same procedure. Now for Alan Een and Alfa Kato glittery. We're going to exchange this group and this group. And once again, when we predict our products, we get our new Alfa Keto acid and a new amino acid here and this is our product of interest

In this problem. We're looking for the Alfa Keto acid that is produced from Trans Am in ation. Our first reaction takes place between Asper Tate and Alfa Kia, glittery in trans emanation reactions. We see an exchange of this group on the amino acid and this oxygen here. When we do this exchange and predictor products, we find that you get a new alpha keto acid here and a new amino acid here. So this new Alfa Keto acid is the product that we're interested in. We can repeat this procedure now, with Isil losing and Alfa Kita glittery. Once again, we see the creation of a new Alfa Keto acid and a new amino acid. And this new Alfa Keto acid is our product of interests.
