In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
Structure of the benzylidene acetal of glucose. In organic chemistry, a benzylidene acetal is the functional group with the structural formula C 6 H 5 CH(OR) 2 (R = alkyl, aryl). Benzylidene acetals are used as protecting groups in glycochemistry.
Glucose circulates in the blood of animals as blood sugar. [5] [7] The naturally occurring form is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. [7] Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose ...

An oligosaccharide has both a reducing and a non-reducing end. The reducing end of an oligosaccharide is the monosaccharide residue with hemiacetal functionality, thereby capable of reducing the Tollens’ reagent, while the non-reducing end is the monosaccharide residue in acetal form, thus incapable of reducing the Tollens’ reagent.

Organic chemistry and especially biochemistry are the areas of chemistry that use the Haworth projection the most. The Haworth projection was named after the British chemist Sir Norman Haworth. [2] A Haworth projection has the following characteristics: [3] Carbon is the implicit type of atom. In the example on the right, the atoms numbered ...
It is produced during the breakdown of glucose, fatty acids, and amino acids, and is used in the synthesis of many other biomolecules, including cholesterol, fatty acids, and ketone bodies. Acetyl-CoA is also a key molecule in the citric acid cycle , which is a series of chemical reactions that occur in the mitochondria of cells and is ...
The chemical structure of cellobiose is derived from the condensation of a pair of β-glucose molecules forming a β(1→4) bond. It can be hydrolyzed to glucose enzymatically or with acid. Cellobiose has eight free alcohol (OH) groups, one acetal linkage, and one hemiacetal linkage, which give rise to strong inter- and intramolecular hydrogen ...
