License. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.
Similarly, What is CH2OH in glucose?
Glucose (C6H12O6) contains six carbon atoms, one of which is part of an aldehyde group. … In this ring, each carbon is linked to a hydroxyl side group with the exception of the fifth atom, which links to a sixth carbon atom outside the ring, forming a CH2OH group.
Additionally, What is the other term for CH2OH? Glucose. (redirected from (CH2OH· (CHOH)4·CHO))
What does OH mean in chemistry?
1 : the chemical group, ion, or radical OH that consists of one atom of hydrogen and one of oxygen and is neutral or negatively charged. 2 : hydroxide sense 1. Other Words from hydroxyl Example Sentences Learn More About hydroxyl.
What is the Iupac name of CH2OH CHOH CH2OH?
This is obviously Glycerol.
What is in a hydroxyl group?
Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom. They readily participate in hydrogen bonding, generating either a net positively or negatively charged ion.
What is an alpha glucose?
What is Alpha Glucose? Alpha glucose is an isomer of D-glucose in which the -OH group present on the first carbon atom is on the same side of the CH2OH group. As per the chair conformation, alpha glucose has a cyclic structure with four -OH groups attached to the carbon chain.
What does monosaccharide stand for?
monosaccharide. / (ˌmɒnəʊˈsækəˌraɪd, -rɪd) / noun. a simple sugar, such as glucose or fructose, that does not hydrolyse to yield other sugars.
What does monosaccharide mean in biology?
: a sugar that is not decomposable into simpler sugars by hydrolysis, is classed as either an aldose or ketose, and contains one or more hydroxyl groups per molecule.
Is OH and HO the same?
HO is a molecule containing positive Hydrogen Oxygen atoms i.e it is a cation. … OH is a molecule containing negative Hydrogen Oxygen atoms i.e it is an anion. Both are ions, HO+ is Hydroxide, OH- is Oxyhydride. Both are acceptable and the only difference is about the charge on oxygen.
What are H+ and OH ions?
The more [H+] ions that are in solution, the more acidic the solution is. The more [OH-] ions in solution, the more basic the solution is. There is a special property of water that makes it act like an acid or base, depending on what is dissolved in it.
Is OH a base or acid?
Is Hydroxide ion (OH–) an acid or base? OH– is a base because of its “proton accepting” ability in aqueous solution, also, when OH– ions are dissolved in solution, the pH value of the solution gradually rises which shows its basic nature.

What is the IUPAC name of ch3cho?
∴ IUPAC name is Ethanal or acetaldehyde. Acetaldehyde is the aldehyde formed from acetic acid by reduction of the carboxy group.
What is hydroxyl alcohol group?
Alcohols contain the hydroxy functional group (-OH), bonded to a carbon atom of an alkyl or substituted alkyl group. The functional group of an alcohol is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond.
Which amino acids contain a hydroxyl group?
Two amino acids, serine and threonine, contain aliphatic hydroxyl groups (that is, an oxygen atom bonded to a hydrogen atom, represented as ―OH). Tyrosine possesses a hydroxyl group in the aromatic ring, making it a phenol derivative.
Is hydroxyl the same as alcohol?
An alcohol is an organic compound that contains one or more hydroxyl (−OH) groups. The general formula for alcohols is R−OH. Do not confuse alcohols with inorganic bases that contain the hydroxide ion (OH−). The −OH group in an alcohol is covalently bonded to a carbon atom and does not ionize in solution.
What is the role of alpha glucose?
For plants to store sugar, they need chains of alpha glucose to build starch. … Both are important forms of glucose which are essential in human metabolism. Alpha glucose and beta glucose both have the same number of carbon atoms, hydrogen atoms, and oxygen atoms.
What is the difference between α glucose and β glucose explain?
Glucose has two cyclic hemiacetal forms. … In the structure of [alpha ] – glucose, the hydroxyl group present on the first carbon atom is down whereas in the structure of [beta ] – glucose, the hydroxyl group present on the first carbon atom is up.
What is monosaccharide example?
Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch). … Some other monosaccharides can be converted in the living organism to glucose.
Where does the word monosaccharide come from?
Monosaccharides are the simplest of these polyhydroxylated carbonyl compounds (saccharide is derived from the Greek word for sugar or sweetness). Monosaccharides are joined together to give rise to oligosaccharides or polysaccharides.
How do you name monosaccharides?
Simple monosaccharides may be named generically based on the number of carbon atoms n: trioses, tetroses, pentoses, hexoses, etc. ; that is, a straight chain of carbon atoms, one of which is a carbonyl group, all the others bearing a hydrogen -H and a hydroxyl -OH each, with one extra hydrogen at either end.
What is monosaccharide and example?
A monosaccharide is a carbohydrate consisting of one sugar unit. Common examples of simple sugars or monosaccharides are glucose and fructose. Both of these monosaccharides are referred to as hexoses, since they have six carbons. … 2: Glucose and fructose are monosaccharides, or simple sugars.
What are monosaccharide give example?
Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch). … Some other monosaccharides can be converted in the living organism to glucose.
What is the biological importance of monosaccharides?
The most important monosaccharide for living things is glucose. It is the main source of chemical energy used for cell functions in all organisms, from bacteria to humans. Plants and certain microorganisms can manufacture glucose through photosynthesis.
