Accepted Answer

Hello, everyone. Today, we have the following problem. Malto truss is found in malted grains and is a product of the breakdown of starch based on its Hayworth structure. What monosaccharide units are present in Malto trios? So we wanna identify the repeating units and identify the an American carbon which is the carbon bound to two oxygens. So if we identify the first structure, we have the following an American carbon. So if we separate that structure and analyze it, we will note that we have a pinos which is a six membered ring with oxygen as one of the carbons in the top, right. And then we have to identify the positions of the hydroxyl groups around the ring for the anomic carbon, the configuration of the hydroxyl group will remain the same. So while it was bonded to another molecule or the second molecule, the bomb was pointing down. So the hydroxyl group and the subunit will also point down no, if we look at the hydroxy group on carbon two being down on carbon three, being up on carbon four being down, we can note that this is the structure of glucose. And then we wanted to start determine the zero chemistry and the isomer. So because the primary alcohol group on carbon five is pointing up, we know that this is the D isomer. And then lastly, since the hydroxy group, one carbon one is pointing down or is trans from the primary alcohol group, one carbon five, this is the alpha aimer. So in putting this all together, we would essentially have three units of alpha D glucose followed by pinos. And with that, we have solved the problem overall, I hope is helped. And until next time.
