Fructose, glucose, and galactose
are regarded as dietary monosaccharides since they are readily absorbed by the small intestines. They are hexoses with a chemical formula: C
6
H
12
O

. Glucose and galactose are aldoses whereas fructose is a ketose. Glucose is a monosaccharide that occurs naturally and is ubiquitous.
What food is an example of a monosaccharide?
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. Glucose is abundant in many plant sources, and makes up sweeteners such as corn sugar and grape sugar.
What are 3 monosaccharides together?
Monosaccharides with three carbon atoms are called
trioses
and these are the smallest monosaccharides, such as dihydroxyacetone and d- and l-glyceraldehyde. Those composed of four carbon atoms are called tetroses, those with five carbons are called pentoses, those of six carbons are hexoses, and so on.
What is an example of monosaccharide quizlet?
An example of a monosaccharide; molecular formula is
C6H12O6
. Starch, glycogen and cellulose are examples of a polymer; the monomer for each of them is glucose. … Adding more monosaccharides to the reaction will produce a polysaccharide and more water molecules.
What are the five monosaccharides?
Examples of monosaccharides are
glucose, fructose, galactose, ribose, and deoxyribose
.
What is a monosaccharide simple definition?
:
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. — called also simple sugar.
What is the most common monosaccharide in food?
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 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.
How do you know if something is a monosaccharide?
Monosaccharides are the simplest unit of carbohydrates. They’re composed of carbon, hydrogen, and oxygen atoms, and they cannot be broken down further since they are already in their simplest form. Their general formula is
(CH2O)n
, where n is any number equal or greater than 3.
Which one is not a monosaccharide?
The correct answer is option (D)
Sucrose
. Sucrose is not a monosaccharide. Sucrose consists of glucose and galactose. Hence, sucrose is a disaccharide.
Is glycogen a monosaccharide?
| Carbohydrates | Monosaccharides Disaccharides Polysaccharides | Glucose Sucrose Starch | Galactose Maltose Glycogen | Fructose Lactose Cellulose |

What are the three examples of monosaccharides quizlet?
- Examples of Monosaccharides. Frutose, Galactose, Glucose (C6h12o6)
- Glucose. (C6H12o^ produced by plants during photosynthesis.
- Examples of Disaccharides. Cellulose, Chitin, Glycogen, starch.
What is the difference between glycogen and starch?
Glycogen is the
energy storage
carbohydrate that is found mainly in animals and fungi whereas Starch is the energy storage carbohydrate that is found predominantly in plants. Glycogen is made up of the single-molecule whereas starch is made up of two molecules namely amylose and amylopectin.
How many different types of monosaccharides are there?
There are
nine common monosaccharides
found in vertebrate glycoconjugates (Figure 2.4). Once incorporated into a glycan, these nine monosaccharide building blocks can be further modified to generate additional sugar structures.
What are 4 examples of polysaccharides?
Common examples of polysaccharides are
cellulose, starch, glycogen, and chitin
.
Why are monosaccharides reducing sugar?
All monosaccharides are reducing sugars because
they either have an aldehyde group (if they are aldoses) or can tautomerize in solution to form an aldehyde group (if they are ketoses)
. This includes common monosaccharides like galactose, glucose, glyceraldehyde, fructose, ribose, and xylose.
