The hydrolylation reaction introduces hydroxyl groups(-OH) to the C60 molecule.
Acetate fiber is known as modified orsecondary acetate having a two or more hydroxyl groups.
By the entrance of amino or hydroxyl groups into the molecule dyestuffs are formed.
Reaction occurs onlyafter opening of the anhydride ring, e.g. by secondary hydroxyl groups in the epoxy resin.
Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
In the natural compound,the isopropyl group is in the trans orientation to both the methyl and hydroxyl groups.
In addition, the carbon atoms attached to the hydroxyl groups are easily oxidized to form aldehydes, ketones or acids.
The commercially used epoxy polymers aremanufactured when a compound reacts with acidic hydroxyl groups and epichlorohydrin.
The terminal hydroxyl groups(―OH) can serve as dyeing sites, but PET is difficult to dye because the individual chains pack tightly.
The anhydroglucose unit is the fundamental repeating structure of cellulose andhas three hydroxyl groups which can react to form acetate esters.
When not less than 92% of the hydroxyl groups are acetylated, the term triacetate may be used as a generic description of the fiber.
The Degree of Substitution(DS) of a given form of methylcelluloseis defined as the average number of substituted hydroxyl groups per glucose.
The presence of multiple hydroxyl groups(oxygen-hydrogen,-OH) makes ascorbic acid extremely hygroscopic, meaning it attracts and binds water to itself.
In 2001, in two simultaneously publishedarticles they showed that under normal oxygen levels, hydroxyl groups are added at two specific positions in HIF-1α.
(oistros, literally meaning"verve or inspiration") and-diol, a chemical name and suffix indicating that this form of steroid andsex hormone is a type of alcohol bearing two hydroxyl groups.
Halotestin and many of its metabolites contain two polar hydroxyl groups, leading to intermolecular hydrogen bonding that increases their boiling point and reduces volatility.
The semisynthetic acetate rayon, produced by acetylation of chemical cellulose, has 200-300 glucose units with 75 percent of the hydroxyl groups converted to acetates.
The team suspects that these hydroxyl groups exist globally across the asteroid in water-bearing clay minerals, meaning that at some point, Bennu's rocky material interacted with water.
In 2001, in two simultaneously published articles Ratcliffe andKaelin showed that under normal oxygen levels, hydroxyl groups are added at two specific positions in HIF-1α.
These compounds are typically diphenols(they have two hydroxyl groups per benzene ring),grouped together in clusters of two or more structural units called dimers, trimers, or polymers.
While most substituents act as auxochromes, sulfonates are present only to increase the solubility of the dye, which is also improved by amino groups, hydrochlorides thereof, and hydroxyl groups.
In addition to the general performance of methyl silicone oil,it also has reactive hydroxyl groups, it can be made available some new material or crosslinked into elastomers(or membrane).
As there is fair quantity of relatively active Si-H bonds in the molecule, under the action of catalysts it can react with chemicals containingactive groups such as double bonds or hydroxyl groups.
Hyaluronic acid moleculescontain a large amount of carboxyl groups and hydroxyl groups, forming intramolecular and intermolecular hydrogen bonds in aqueous solution, which makes it have a strong water retention effect.
An aldose is a monosaccharide(a simple sugar) with a carbon backbone chain with a carbonyl group on the endmost carbon atom,making it an aldehyde, and hydroxyl groups connected to all the other carbon atoms.
The principle of mercerizing: The association of NaOH with the hydroxyl groups of cotton cellulose molecules brings in a large number of water molecules, which causes the cotton fibers to swell violently and changes the supramolecular structure.
