The hydrogen group (-H) and hydroxyl group (-OH) are labeled on a glucose diagram as follows:
H HO
| |
H--C--OH or HO--C--H
| |
OH H
The hydroxyl group (-OH) gives glucose its water-soluble properties and its ability to form hydrogen bonds with other molecules. The hydrogen group (-H) is responsible for glucose's acidic properties and its ability to donate a hydrogen ion (H+) in solution. Together, these groups contribute to glucose's role as an important energy source in the body.

What is the similar about :Galactose,fructose,ribose and deoxyribose. And what is the difference?
Similarities:
Galactose, fructose, ribose, and deoxyribose are all monosaccharides, meaning they are simple sugars that cannot be further hydrolyzed. They are all also carbohydrates that contain the elements carbon, hydrogen, and oxygen.
Differences:
1. Chemical structure: Galactose, fructose, ribose, and deoxyribose have different chemical structures. Galactose and glucose are both aldoses, which means they have an aldehyde group (-COH) as their terminal functional group. Fructose, on the other hand, is a ketose, which means it has a ketone group (-CO-) as its terminal functional group. Ribose and deoxyribose are both aldopentoses, but deoxyribose lacks one oxygen atom compared to ribose.
2. Source and function: Galactose is found in lactose (a disaccharide made of glucose and galactose) and is important in lactose metabolism. Fructose is commonly found in fruits and is often used as a sweetener. Ribose is a component of RNA (ribonucleic acid) while deoxyribose is a component of DNA (deoxyribonucleic acid).
3. Isomers: Galactose and glucose are isomers of each other, meaning they have the same chemical formula but different arrangements of atoms. Fructose, ribose, and deoxyribose are not isomers of each other or with any of the other monosaccharides mentioned.
4. Role in the body: Galactose and glucose are two of the main sugars that the body uses for energy, while fructose is metabolized differently and is processed by the liver. Ribose and deoxyribose are important for the synthesis of nucleotides, which are the building blocks of DNA and RNA.
