Sucrose, which is nonreducing, does not form an osazone. A typical reaction showing the formation of an osazone. D-glucose reacts with phenylhydrazine to give glucosazone. The same product is obtained from fructose and mannose. General steps in osazone formation
Pigment Yellow 97, a popular yellow colorant, is a hydrazone. [6]Hydrazones are the basis for various analyses of ketones and aldehydes. For example, dinitrophenylhydrazine coated onto a silica sorbent is the basis of an adsorption cartridge.
Composite image showing young stars in and around molecular cloud Cepheus B.. This is a list of star-forming regions located in the Milky Way Galaxy and in the Local Group.Star formation occurs in molecular clouds which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions.
Ozone does not form organochlorine compounds, nor does it remain in the water after treatment. Ozone can form the suspected carcinogen bromate in source water with high bromide concentrations. The U.S. Safe Drinking Water Act mandates that these systems introduce an amount of chlorine to maintain a minimum of 0.2 μmol/mol residual free ...
In 2024, a group led by researchers at the Massachusetts Institute of Technology reported the discovery of 2-methoxyethanol in a star-forming region within the nebula NGC 6334. [5] The discovery was made by examining in the laboratory the spectral signature of 2-methoxyethanol as the molecule was made to rotate.
An oceanic core complex, or megamullion, is a seabed geologic feature that forms a long ridge perpendicular to a mid-ocean ridge. It contains smooth domes that are lined with transverse ridges like a corrugated roof. They can vary in size from 10 to 150 km in length, 5 to 15 km in width, and 500 to 1500 m in height.

The structure of the octameric core complex was revisited seven years later and a resolution of 3.1 Å was elucidated for its crystal at a high salt concentration. Though sequence similarity is low between the core histones, each of the four have a repeated element consisting of a helix-loop-helix called the histone fold motif. [4]
