Practical Report (Determination of blood glucose levels and qualitative carbohydrate tests)
Introduction:
The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds which have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of energy in both plants and animals (Ahmed 2014). They are built from monosaccharides. These monosacchradies are the small molecules that consists of three to nine carbon atoms and differ in size and in the stereochemical configuration at one or more carbon centers. The simplest carbohydrates also contain either an aldehyde or ketone compounds (freeman 2002). Carbohydrates are classified as simple and complex carbohydrates. The classification of carbohtdydrates is based on the chemical structure of the food and how fast it absorbs. Simple carbohydrates contains single or double sugars in their chemical structure whereas complex carbohydrates consists of three or more sugars (ahmed 2014). There are four major types of carbohydrates depending on their chemical composition.
1) Monosacchrides: Mono means single and saccharides refer to sugar. These are the simple form of carbohydrates that consists carbon, hydrogen and oxygen in the ratio of 1:2:1 (Ahmed 2014). Examples: Glucose, fructose and
1. Carbon, hydrogen, and oxygen make up carbohydrates. Small carbs contain twice as many hydrogen atoms as oxygen atoms; simple sugars, called monosaccharides, are the basic building blocks for
Carbohydrates have two functions which is, provides short term energy and structure in some organisms. They have an atomic makeup of Carbon, Hydrogen, and Oxygen, with a 2:1 ratio of Hydrogen to Oxygen. The monomer is a monosaccharide which contains a single sugar. A couple examples of this would be glucose, fructose, and deoxyribose which is found in DNA. Yet, foods with this monomer in it would be mostly fruits, candy, and soda. Carbohydrates also have a polysaccharide which is a polymer made of many monosaccharides strung together. Some examples of these are starch, glycogen, cellulose, and chitin. A starch is storage from glucose in plants(potatoes, pasta, waffles, and toast). Glycogen is storage from glucose in animals. Cellous is structure in plants (cell wall). Chitin is structure in animals (exoskeleton).
(Driskell 29) These simple carbohydrates are easily broken down, converted into glucose for the body and easily flow into the blood stream. The downside to this form of carbohydrates is that they are most common in the form of refined sugars or refined flours which retain very few vitamins after being processed. (“HealthStyle Fitness”) As the body uses this form of glucose a cycle begins which involves fluctuations of high and low blood sugar. This cycle works when blood sugar rises after the consumption of simple carbs and then as the blood sugar begins to drop the body demands more simple carbs to bring blood sugar levels back to up. The cycle that is formed essentially keeps the body from burning body fat because there is a continuous demand and consumption of simple carbohydrates. The second form of carbohydrates is that of complex carbohydrates which consist of polysaccharides, three or more monosaccharides. These complex carbs are found in the form of starch, fiber and glycogen (animal starch). Those complex carbohydrates consumed in the form of starch are found in plant foods like corn, wheat, potatoes, cereals, pastas, and beans. When they are broken down these carbs allow for the slow production and release of glucose into the blood stream and allowing for a consistent blood sugar level. (Guthrie 27) Dietary fiber is another form of complex carbs which are present in plant foods because fiber is
Carbohydrates: any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.
A monosaccharide is a carbohydrate that doesn’t hydrolize. A disaccharide is a group of that yield monosaccharides on hydrolosis. Lastly, polysaccharide is a carbohydrate that contains more than three monosaccharide units per molecule.
Carbohydrates are composed of carbon, hydrogen, and oxygen. Carbohydrates can come from fruits, vegetables, and grains. There are two different kinds of carbohydrates. The first being simple carbohydrates, which are sugars. Glucose, fructose, and galactose fall under the sugar category. Then you have your complex carbohydrates, which are starch in grains, glycogen stored in our muscles, and fiber. When it comes to energy within our body glucose is a major source of energy. When our body does not get enough carbohydrates to supply enough glucose, our body will make glucose from proteins. I applied this to my life by making sure I eat fruits, vegetables, and grains to get my carbohydrates every single
The purpose of this experiment is to exemplify how differences in molecular weight allow separation of polymers from their monomers. Methods of dialysis and gel filtration chromatography will be used to separate a glucose monomer from a starch polymer. Colorimetric glucose oxidase assay will be used to monitor the presence of glucose and a colorimetric iodine assay will be used to monitor the presence of starch in prepared solutions after separation
Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such as pasta, wheat and grains, rice, potatoes, fruits and sugars. Carbohydrates are broken down into
a) What is meant by “sugar”? What is a “carbohydrate”? How are sugars and carbohydrates related?
Plasma insulin concentration was at its lowest during the fasting time period. Concentration was about 68 during that time.
First of all, let’s discuss the carbohydrate molecule, which contains carbon, oxygen, and hydrogen atoms. Carbohydrates are the most important source of energy for our body and our digestive system changes carbohydrates into glucose (sugar). Carbohydrates contain monosaccharides (one simple sugar), disaccharides (two simple sugars), and polysaccharides (many simple sugars). These simple sugars are joined by glycosidic bonds to form
Carbohydrates are composed of carbon, hydrogen, and oxygen. Monosaccharides are the smallest carbohydrates and act as monomers for the larger carbohydrates. Disaccharides are two monosaccharides bonded together. Sucrose is an example of a disaccharide. Polysaccharides are many monosaccharides bound together. Unbranched patterns in carbohydrates like cellulose are normally used for structure. Moderately branched carbohydrates like starch are normally used for energy storage in plants. Highly branched carbohydrates like glycogen are normally used for energy storage in animals. Another type of macromolecule is the lipid. The most common lipids are fats. Fats contain the molecule glycerol bonded to three other fatty acids. Saturated fats contain a string of single bonds, forming a straight molecule. This kind of fat is also solid at room temperature. Unsaturated fats are bent because of some double bonds. These fats are liquid a room temperature. Another type of macromolecules are nucleic acids. Nucleic acids are responsible for the storage, expression, and transmission of genetic information. The monomer of the nucleic acid is the nucleotide. Nucleotides are made of a phosphate group, pentose sugar, and rings of carbon and nitrogen. The two types of nucleic acids are DNA and RNA. DNA is double stranded, has deoxyribose for its pentose sugar, contains thymine as a base, and stores genetic information. RNA is single stranded, has
Over the past 8 weeks I have taken the initiative to change the routine that the night nurses take the morning blood sugars. I have researched, educated, and implemented a plan to safely take a blood sugar that is within 30-60 minutes of the blood sugar being recorded.
Monitoring Blood Glucose Levels Maintaining normal blood glucose levels greatly reduces the risk of experiencing complications due to diabetes. Whether an individual has Type 1 or Type 2 diabetes, regular use of a glucose monitor to determine blood sugar levels will help determine what adjustments to diet, oral medications, or insulin injections may be necessary to achieve good control. What's Glucose?
Carbohydrates are the product that made up from carbon, hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation,example of reducing sugar islactose,maltose,glucose and fructose.All monosaccharides are capable of reducing other chemicals such as copper (II) sulphate to copper oxide.Beside that disaccharides such as maltose and lactose are reducing sugar,however sucrose is non reducing
