Re: fructose as a monomer for a polysaccharide

... the one that makes the ketone group in the open ring form and the oxygen of the ketone is the oxygen in the ring) is bound up into a non-reducing disaccharide as is the case sucrose. This anomeric carbon has the reactive hydroxyl group that I have referred to that is used in the reducing part ...

Re:

... chemists call "non-reducing" while sugars like glucose are "reducing" sugars. We can also use that nomenclature with disaccharide like sucrose, maltose, etc. Sucrose has no reactive hydroxyl group open so it is called a non-reducing disaccharide. Maltose (two glucoses ...

Plant & animal cell - sucrose & glucose

... you are asking for some short-cut! lol :D the main point to explain and think is "glucose" is Monosaccharide and "sucrose" is disaccharide. so sucrose surely will take lots of time to break the glycosidic linkage between glucose and fructose. So whether it is a plant or animal, ...

Re: Yeast fermentation with different carbohydrates

... hypothesis was accepted. I am only carrying out the statistical test between Glucose and Sucrose since Glucose is a monosaccharide and Sucrose, a disaccharide. Also, otherwise I'd have to carry out way too many tests, to compare each sugar with each other. Here are my results: These are averages: ...
