Carbonyl group

a group in which an oxygen atom is double-bonded to a carbon atom: O=C. The carbon atom then has two additional bonds to attach to the rest of the molecule. Organic molecules containing a carbonyl group are a very important, major group of compounds studied in the field of organic chemistry.

can galactose be convert into fructose?

... guess that it is a more favorable reaction to phosphorylate a hydroxyl group on the chain (carbon 1) in a ketose sugar than any of the hydroxyl ... sugars like glucose do not have a hydroxyl group on Carbon 1 and have a carbonyl group instead. You need a hydroxyl group to create the phosphoester ...

Y does H2O2 oxidize lipids much more strongly than proteins?

... that the answers is written thare. It's all because protein has a amide group and amino acid has a carboxyl roup. Both of these groups contain carbonyl arrangements which is said to be stable to oxidation stress. Meanwhile, lipids (e.g. ...

Why does fructose not form polymers like glucose?

... named inulin (mostly described as fructosan). Fructose does have OH group in its anomeric C atom. Fructose is a reducing sugar, because it has a free carbonyl (ketone) group if we dee it as an acyclic form. this reduction involves a keto-enol ...
