today we're going to talk about reducing sugars and also non to reduce sugars. But prior to we perform that, we have to speak around him. Mia settles in a chair halls, i m sorry is critical part of what renders a street reducing or non reducing. Hey, Meus! Atolls room compounds that contain in O. R and also an O. H team at the one American Carbon. So friend have and also O period group in a no. Our group at the one American Carbon and A Settles have to o r teams at the in America Carbon. Now this concerns sugars because reducing sugars have the hemi a settles at the in America carbon due to the fact that the reducing sugars require this O. H group, as opposed to non reducing sugars, which has which lacks in, oh, age groups and therefore have actually a settles. You can see that below we're looking at these two different sugars. This sugar is a model sacha ride, and it's the famous glucose. And as you have the right to see here, it's It's an American carbon In the In America, carbon is just the carbon that's attached to the carbon, Neil. Okay, and also so you have actually again the in America Carbon has an O H. Group. So this is a hemi Asa tall, and also this O. H group is climate able come go and also reduce other compounds here. This sucrose is a dye sacha ride, and also it's an American. Carbon is best here and also this in America Carbon sense. It's connected in this black color acidic bond. That does not have a O. H here to have the ability to reduce. Therefore this is as such non reducing. Currently all dice sack arise space not no reducing. There are some nice sacrifice that space reducing and also this can be seen. We're looking at maltose and lactose currently again, sucrose here it's in America. Carbon is affiliated in this bond, so it is non reducing since it go not have a no h. However, maltose and also lactose do have actually is one American carbon here and also here that has actually an O. H. Team attached, which then this O. H is cost-free to then mitigate other compounds. Now again, another means to look at it is prefer I probably he stated, since this sucrose has a bond, a 12 black acidic bond whereby it's an American carbon is involved. That does not have actually that complimentary O H to then walk on alleviate compounds. However, maltose and also lactose do have a black, acidic bond, which is a 14 black acidic bond that is not entailing the an American carbon. For this reason this and also America carbon is totally free to go and also reduce now. Another means to look in ~ it is when you speak about Benedict. Three agents and also Benedicts complimentary agents is a test provided to be able to detect the existence of reducing sugars. Currently re agents, the Benedicts totally free Agents demands a hem ASA high to it is in able to, um, finding the sugar. The non reduce the to reduce sugar.

For this reason Benedict rations will not work-related with sucrose due to the fact that this 12 black, acidic shortcut is preventing this glucose here from being able to, i summarize, to be able to undergo itemization because that the re certified dealer from Benedict's reagent to react. Therefore those are a few ways to understand what the difference between not reducing and reducing street are
