What is the general formula for carbohydrates?
Carbohydrates have the general formula Cx(H2O)y. The hydrate of carbon is known as carbohydrates. They contain hydrogen and oxygen in the same proportion as in water. It may be noted that there are some carbohydrates which do not conform to the formula Cx(H2O)y, for example, 2-deoxyribose C5H10O4.
What is the chemical reaction of carbohydrate?
The Chemical Reactions of Carbohydrates. reaction, the -OH groups in carbohydrates react quickly with alkylating agents to produce ethers. and methyl iodide, CH3I. Because the products act as protective groups for the reactive -OH functional group, these reactions are frequently utilised in carbohydrate chemistry.
Which of the following is the general formula of carbohydrates Mcq?
6) Which of the following is the general formula of Carbohydrates? Sol: (c) (CH2O)n.
Do all carbohydrates have the same general formula?
All carbohydrates have the general formula Cn(H2O)n. Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. The smallest unit of a carbohydrate is a monosaccharide. Two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide.
What type of chemical reaction takes place for the formation of carbohydrates?
Hydrolysis of disaccharides, oligosaccharides and polysaccharides Hydrolysis of a saccharide means that the bond between two sugar monomers is cleaved (broken), enzymatically or chemically, by the addition of a water molecule. For a disaccharide this means that hydrolysis leads to the formation of two monosaccharides.
Which chemical formula represents a carbohydrate and why?
The term carbohydrate can basically be translated into “carbon water”. Therefore, the typical formula for a carbohydrate is CH2O . The most common sugar is glucose from the photosynthesis reaction. Glucose has a formula of C6H12O6 .
Which of the following is the general formula of carbohydrates * 2 points?
What is the simplest form of carbohydrates?
1.1 Monosaccharide. Monosaccharides are the simplest form of carbohydrates that are easily absorbed in intestine compared to the disaccharide, oligosaccharide and polysaccharide. The monosaccharide consists of single unit which contains carbon chain of three to six carbon.
Which of the following does not follow the general formula of carbohydrates?
The correct answer is option 3, i.e. Rhamnose. The general formula of carbohydrate is Cx(H2O)Y. Rhamnose is a carbohydrate and its chemical formula is C6H12O5. This carbohydrate does not follow the general formula of carbohydrates.
What is the general formula of polysaccharides?
Polysaccharides are polymeric carbohydrates composed of long chains of monosaccharide units joined by glycosidic linkages with a general formula of (C6H10O5)n, 40≤n≤3000.
How is co2 converted into carbohydrates?
The cycle of reactions that converts carbon dioxide to carbohydrates is called the Calvin cycle, after M. Calvin, who received the Nobel Prize in chemistry in 1961 for his work on determining the path of carbon in photosynthesis. These reactions have several features in common.
What is the chemical structure of carbohydrates?
The chemical formula of a carbohydrate is Cx(H2O)y, which denotes some carbons (C) with some water molecules (H2O) attached—hence the word carbohydrate, which means “hydrated carbon.”
Which one of the following does not follow general formula of carbohydrate?
Is general formula of monosaccharides?
the general formula of monosaccharides is (CH2O)n, and polysaccharides are formed by monosaccharide units bound together by glycosidic linkages.
What is the simplest form of carbohydrate quizlet?
Sugar: The simplest of Carbohydrates.
What is the chemical formula of glycogen?
C24H42O21Glycogen / Formula
What is general formula of oligosaccharides?
Raffinose family of oligosaccharides It has a chemical formula of C18H32O16. Thus, it is a trisaccharide. When hydrolyzed with enzyme α-galactosidase, it yields D-galactose and sucrose.
Which of the following equation show correct conversion of CO2 and H2O into carbohydrates in plants?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2.
Does reduction of CO2 to carbohydrates?
Carbohydrate biosynthesis requires a source of electrons to ultimately reduce carbon dioxide to carbohydrate. The source is the oxidation of the NADPH produced during photosynthetic electron transport.
What is the general formula of monosaccharides disaccharides?
What is the simplest type of carbohydrate?
Monosaccharides. Monosaccharides are the simplest carbs, in that your body cannot break them down further. This allows your body to absorb them quickly and easily, with the exception of fructose.
What is the general formula of cellulose?
Cellulose is an organic compound with the formula (C6H10O5)n, a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units.
What is the chemical formula for the sugar carbohydrate produced by photosynthesis?
Glucose (C6H12O6) is a common example of the monosaccharides used for energy production. Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions.
What is a conversion of CO2 into carbohydrates?
The cycle of reactions that converts carbon dioxide to carbohydrates is called the Calvin cycle, after M. Calvin, who received the Nobel Prize in chemistry in 1961 for his work on determining the path of carbon in photosynthesis.

How to find the general formula of carbohydrate?
You can download Biomolecules Cheat Sheet PDF by clicking on Download Button Below General Formula of Carbohydrate The general formula for carbohydrate is Cx(H2O)y. Although, it must be remembered that this is just a general formula. There are various exceptions to this that we will see. Let us take a look at Acetic Acid which is CH3COOH.
What are the starting materials of a single replacement reaction?
The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound. When a replacement reaction occurs, a new aqueous compound and a different pure element will be generated as products. The general pattern of a single replacement reaction is shown below.
What is the difference between single replacement and double replacement reactions?
In a double replacement reaction, there is interchanging of ions or atoms between the reactants. Single replacement reactions or single displacement reactions involve the replacement of an atom or an ion from one compound by a more reactive compound. This type of a reaction can be depicted in the following manner:
