A carbohydrate with 6 carbons and a ketone functional group is called
a(n) ketohexose
What is the name of the 6 carbon monosaccharides?
The main monosaccharides are the
hexoses
(simple sugars in which the molecules contain six carbon atoms)—these include glucose (known also as dextrose), fructose
1
(commonly called levulose), galactose, and mannose (Eliasson, 2016).
Which of the following is a carbohydrate with 6 carbons and a keto group?
Question: Which of the following is a carbohydrate with 6 carbon atoms and a keto group as the functional group?
galactose glyceraldehyde O glucose fructose Odihydroxyacetone
.
What is a monosaccharide with a ketone group?
A ketose
is a monosaccharide containing one ketone group per molecule. The simplest ketose is dihydroxyacetone, which has only three carbon atoms, and it is the only one with no optical activity.
Which out of the following is a carbohydrate with 6 carbon atoms and a ketone group as the functional group?
Fructose
is ketohexoses having six carbon atoms with 5 having a hydroxyl group and the main functional group is a ketone.
What is the functional group of carbohydrates?
Naming the Major Functional Group in a Carbohydrate
Sugars, or carbohydrates, have two major functional groups:
an aldehyde or a ketone
(both are collectively called carbonyls), and an alcohol functional group. Carbohydrates generally have multiple alcohol functional groups, so we never focus on those.
What is difference between aldose and ketose?
Ketose and aldose are monosaccharides which can be differentiated based
on the group they contain
. An aldose is defined as a monosaccharide whose carbon skeleton has an aldehyde group. They are primarily found in plants. Ketose is a monosaccharide whose carbon skeleton has a ketone group.
What is the simplest monosaccharide?
The simplest monosaccharides are said to be the
trioses
which are the two three-carbon trioses. We can have three possible trioses: L-Glyceraldehyde, D-Glyceraldehyde, and dihydroxyacetone or just glycerone.
What is the most common monosaccharide?
Glucose
, sometimes referred to as dextrose or blood sugar, is the most abundant monosaccharide but, on its own, represents only a very small amount of the carbohydrate consumed in the typical diet. Instead, glucose is usually consumed when it is linked to other sugars as part of a di- or polysaccharide.
What is a 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).
Which type of carbohydrate is the largest?
The most abundant carbohydrate,
cellulose
, is a structural component of the cell wall of plants and many forms of algae.
What are examples of ketose?
Hexoses are six-carbon ketoses. Examples include
fructose, sorbose, and psicose
. Heptoses are seven-carbon ketoses, such as sedoheptulose. Octoses are eight-carbon ketoses (e.g. D-manno-octulose).
Are aldoses reducing sugars?
Monosaccharides which contain an aldehyde group are known as aldoses, and those with a ketone group are known as ketoses. The aldehyde can be oxidized via a redox reaction in which another compound is reduced. Thus, aldoses are
reducing sugars
.
What is oligosaccharide formula?
Common oligosaccharides
It is a trisaccharide formed from the combination of three monomers: galactose, glucose, and fructose. It has a chemical formula of
C

Why carbohydrates are called saccharides?
Monosaccharides: The Sweet Ones
In biochemistry, carbohydrates are often called saccharides,
from the Greek sakcharon, meaning sugar
, although not all the saccharides are sweet. The simplest carbohydrates are called monosaccharides, or simple sugars. … The hexose D-glucose is the most abundant monosaccharide in nature.
What functional group is the most evident in a carbohydrate?
Since carbohydrates are
aldehydes or ketones with two or more hydroxyl groups
, the simplest monosaccharides are the three-carbon compounds glyceraldehyde and dihydroxyacetone (DHA), which are shown in the figure below.
