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…

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…

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…

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…

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.

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…
