What else can I help you with?
Is gentiobiose reducing or non-reducing sugar?
yes it is a reducing sugar, it has a free anomeric OH group. thus it can also mutarotate
When the linear form of glucose cyclizes the product is an?
When the linear form of glucose cyclizes, it forms a six-membered ring structure known as a hemiacetal. This ring structure is called a pyranose ring in the case of glucose and is commonly found in sugar molecules like glucose, fructose, and galactose.
Is a hemiacetal a reducing sugar?
Yes, a hemiacetal is a type of sugar that can act as a reducing sugar.
Does sucrose have a hemiacetal group?
No, sucrose does not have a hemiacetal group. Sucrose is a disaccharide composed of glucose and fructose linked via a glycosidic bond, with no free hemiacetal groups present.
Does gentiobiose undergo mutarotation?
Yes, since galactose is a monosaccharide it can undergo mutarotaion just like glucose. The only difference between glucose and galactose is the side the OH and H are on, on the carbon atom #4. When galactose becomes a in chain form, drawn in Fischer formula the OH will be on the left side instead of the right side. This is how you get Galactose α or β, at the end of the mutarotation the chain can link back into a ring either way, α with the carbon #1's OH on the bottom and H on top, or β with the OH on top and H on the bottom (Haworth formula).

Is gentiobiose a reducing or non-reducing sugar?
Gentiobiose is a non-reducing disaccharide because both of its reducing ends are involved in the glycosidic bond formation between the two glucose units. This means it does not have a free anomeric carbon available to reduce other substances.
What is the difference between a hemiacetal and a hemiketal?
The main difference between a hemiacetal and a hemiketal is the functional group involved. A hemiacetal forms when an alcohol group and an aldehyde group are involved, while a hemiketal forms when an alcohol group and a ketone group react. Additionally, in a hemiacetal, one oxygen atom is part of the alcohol group and one is part of the aldehyde group, whereas in a hemiketal, both oxygen atoms are part of the alcohol group.
How do you write hemiacetal?
It is written like this R-CH(OR)-OH
Why fehling reaction give negative result with starch?
Due to absence of free hemiacetal group
Grouping and marshalling in balance sheet?
grouping and marshalling in balance sheet grouping and marshalling in balance sheet
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
What is b-glycosides?
This is the transformation of unprotected sugars.This also covers compounds with hemiacetal bonds with groups of sugars and chemical compounds.
