Identification of Unknown Carbohydrates

Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose, fructose, maltose, lactose, sucrose and starch. There was six tests that were carried out to help identify them, these were: Iodine Test, Solubility in Water, Benedict’s test, Acid Hydrolysis, Barfoed test and Diastix test. Aim The aim of the experiment which was carried out was to identify the unknown carbohydrates by subjecting them to a series of biochemical tests. The tests were as follows: Iodine, Solubility, Benedict’s, Acid Hydrolysis, Diastix and Barfoed test. Methods There was 1g of each solid carbohydrate contained in bottles labelled A-F, 10ml of…

Glucose Improves Listening Span

This study was conducted to see the consequences for listening comprehension by examining the effects of a glucose drink on performance. The researchers predicted a hypothesis. The hypothesis being that listening span will be sensitive to glucose consumption. Students who fasted overnight would improve after drinking a glucose drink, where the placebo drink would not improve performance after fasting. The hypothesis was supported. There was an alternate/ research hypothesis used in this study. The independent variable was the glucose and the placebo that was being used in the study. It also shows that there was a difference between the two groups being tested. The numbers show that the glucose level was higher when real sugar drinks were being used. The…

An Introduction to Carbohydrates

Carbohydrate – sugars, encompasses the monomers, called monosaccharides, small polymers called oligosaccharides, and large polymers called polysaccharides 5.1 Sugars as Monomers 1. How Monomers Differ a. Monosaccharide – simple sugar, monomer i. Carbonyl group serves as a distinguishing feature 1. At end of molecule, forms an aldehyde sugar (aldose) 2. In middle of molecule, forms a ketone sugar (ketose) ii. Presence of a carbonyl group along with multiple hydroxyl groups provides an array of functional groups in sugars iii. Number of carbons also varies in monosaccharides 3. Trioses (3), pentoses (5), hexose (6) iv. Differences of structure is responsible for differences in function v. Rare to see sugars exist in linear forms 4. Tend to form rings in aqueous solution…

Characteristics of nutrients and their benefits to the body

In order to obtain good health everyone must consume a balanced diet. To do this we must eat recommended amounts of food from the five food groups which are, fruit and vegetables, meat, fish & alternatives, bread, cereals & potatoes, milk & dairy and foods which contain fats and sugar. These five food groups contain the seven components of a balanced diet they are, protein, carbohydrates, lipids, vitamins, minerals, fibre and water. Proteins are made up of long chains of amino acids, there are 22 different types of amino acid and the body needs all of them to function properly. There are many forms of protein, which all play an important role in the function of the body. For example,…

Analysis of Macromolecules in Tissue

The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4, 0.8, 1.2, 1.6, 2.0 mg/ml of bovine serum were used to determine absorbance with a spectrophotometer. Two additional samples were made; one was blank and the other was for the specific homogenate sample. Then 3 microliters of bradford assay reagent, which indicates the amount of protein present by color, was added to all samples. The spectrophotometer was zeroed at 595 nm. A standard curve was made with the different…

The Limits of Amylase

Abstract This report explains the purpose of this experiment in a way that conveys information to the reader about Amylase’s ability to withstand acidic or basic pH. To do this, two test tubes were both filled with 5mL of a 5% amylase solution. The first one was filled with an acid, while the other was filled with a base. After dropping liquid Iodine and Benedict’s solution into each one, the tube with a basic pH tested positive for glucose. The acidic solution tested (mostly) negative for glucose, although there were trace amounts at the bottom. Overall, my conclusion is that only acidic solutions inhibit Amylase’s ability to digest starch. Background The goal of the experiment is to test whether or…

An informative essay on diabetes

Modern life provides better living conditions, but also brings no less depressing. Diseases in humans more, there are very dangerous diseases, but medicine is still the solution, one has to mention diabetes. In the past few decades, diabetes is one of the ten major causes of death in most countries around the world. According to the world Diabetes Federation, diabetes(also called diabetes mellitus) has claimed the lives of 4.6 million people each year. Do you want to understand clearly about how to know diabetic symptoms and how to prevent it? There are some useful information for you. First of all, increased urination at night, hunger, thirst, rapid weight loss, limbs inflammation, blurred vision, and fatigue are the first warning signs…

Differences and Similarities between Respiration and Photosynthesis

Cellular RespirationPhotosynthesis OrganellesMitochondriaChloroplast Organelle StructuresThe double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller, unwrinkled bag. The two membranes create distinct compartments within the organelle, and are themselves very different in structure and in function.Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches (sugars) are created. One thylakoid stack is called a granum. The thylakoids have chlorophyll molecules on their surface. That chlorophyll uses sunlight to create sugars. The stacks of sacs are connected by stromal lamellae. The lamellae act like the skeleton of the chloroplast, keeping all of the sacs a safe distance from each other…
