What ketohexose and aldohexose are present in melezitose?
Melezitose is composed of the ketohexose fructose, along with two units of the aldohexose glucose. It is a trisaccharide made up of glucose-fructose-glucose.
What element is found in amino acid that isn't found in simple sugars like glucose and fructose?
POTASSIUM
Why does glucose pass through the membrane faster then mannose and galactose?
Glucose passes through the membrane faster than mannose and galactose because glucose is the primary energy source for many cells and is recognized and transported more efficiently by glucose transporters present on the cell membrane. Mannose and galactose have different transporter proteins with lower affinity and therefore pass through the membrane at a slower rate.
If benedicts reagent turns red what substance is present?
If Benedict's reagent turns red after adding it to a solution, it indicates the presence of reducing sugars such as glucose or fructose. The red color is a result of the reduction of copper (II) ions in the reagent to copper (I) oxide by the reducing sugars.
Which one of the following is an example of a structural polysacharride A trehalose B glycogen C amylose D fructose E hyaluronate?
B glycogen is an example of a structural polysaccharide. It is a branched polymer of glucose that serves as a storage form of energy in animals and fungi. Trehalose, fructose, and hyaluronate are not structural polysaccharides, while amylose is a linear polymer of glucose and is considered a storage polysaccharide.
Which monosaccharide is present is all 3 disaccharides?
Glucose is the monosaccharide present in all three disaccharides: sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
Which two functional groups are present in all mono saccharides?
galactose and fructose
What ketohexose and aldohexose are present in melezitose?
Melezitose is composed of the ketohexose fructose, along with two units of the aldohexose glucose. It is a trisaccharide made up of glucose-fructose-glucose.
Is the sugar in figs fructose glucose or sucrose?
The sugar in figs is mainly in the form of natural sugars like glucose and fructose. Sucrose, which is a combination of glucose and fructose, may also be present in smaller amounts.
What element is found in amino acid that isn't found in simple sugars like glucose and fructose?
POTASSIUM
Why is the Benedict test not exclusive to glucose?
The Benedict test will return a positive value for any reducing sugar. It will work with fructose, for example. Benedict solution oxidizes all the reducing sugars such as glucose, galactose and fructose. This implies that a positive result of Benedict's test can be any of the reducing sugars, not necessarily glucose. It will oxidize the carbonyl (which present in all type of sugar classes). So if we get a positive result in the Benedict test, it is not necessarily glucose; it could be galactose or fructose that also a reducing sugar. So Benedict test can't be used to assure glucose.
What is the difference between lactose and galactose?
Lactose is a disaccharide sugar made up of galactose and glucose molecules. Galactose is a monosaccharide sugar that is found in milk and dairy products. Lactose needs to be broken down into galactose and glucose in the body in order to be absorbed.
Is galactose a monomer?
Yes, galactose is a monomer, or more specifically a monosaccharide, due to the fact that it is a simple sugar. It is one of the three most common sugars present in biology, along with glucose and fructose, and is able to bond with other simple sugars to form chains, or carbohydrates.
What chemical elements are in monosaccharide?
The chemical elements present in monosaccharides are carbon (C), hydrogen (H), and oxygen (O). These elements combine in specific ratios to form different types of monosaccharides, such as glucose, fructose, and galactose.
Why does glucose pass through the membrane faster then mannose and galactose?
Glucose passes through the membrane faster than mannose and galactose because glucose is the primary energy source for many cells and is recognized and transported more efficiently by glucose transporters present on the cell membrane. Mannose and galactose have different transporter proteins with lower affinity and therefore pass through the membrane at a slower rate.
Can glucose be found in fruits?
Yes, but it is not available as easily as fructose. Glucose is present in all living cells as the source of energy to produce ATP for metabolism.
Monosaccharides produced by hydrolysis of sucrose?
The monosaccharides produced by hydrolysis of sucrose are glucose and fructose. Sucrose is a disaccharide composed of one molecule of glucose and one molecule of fructose linked together, so when it is broken down by hydrolysis, these two monosaccharides are released.
