Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that

Carbohydrates‚ Proteins‚ lipids‚ and nucleic Acid Lab Exercise 6 Date: 9/17/12 Bio 102-11 Purpose the purpose of this experiment was to perform test to detect the presence of carbohydrates‚ proteins‚ lipids‚ and nucleic acids. Explain the importance of a positive and a negative control in biochemical test. Use biochemical test to identify an unknown compound. Background Most organic compounds in living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids they are called macromolecules

L.O. 1.1 and 1.2 Carbohydrates are sugars and they are the primary source of energy for our vital functions such as breathing and sleeping. There are two types of carbohydrates‚ simple and complicated. Monosaccharides‚ disaccharides and polysaccharides. L. O. 1.2 Carbohydrates are split into different classifications depending on how many molecules they have. Monosaccharide: one sugar

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

#) Identifying Carbohydrates (First inital and last name of lab partner) Purpose The purpose of this lab is to learn how to identify different forms of carbohydrates by conducting the Benedict and Iodine test. Theory The theory for this concept is that if in the benedicts test the carbohydrate reacts‚ it is a monosaccharide. If it reacts in the Iodine test it is a polysaccharide. If no reaction occurs in either test the carbohydrate is a disaccharide. Data Type of carbohydrate | Benedicts Test

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays

With an improved procedure the question could have been answered with this methodology‚ but the aim was to find out the affect of carbohydrates on blood glucose levels‚ but the methodology provided an answer for the question without going into depth of the biochemistry and carbohydrate structure. This could be solved by amending the aim or by constructing some sort of pre-experiment with the bread that would be used to compare the structure of Danskt Rågbröd

In this lab we employed various assays utilizing a biuret reagent‚ coomassie brilliant blue reagent‚ and ultraviolet light in order to determine the identity of six unknown solutions and the concentration of a bovine serum albumin sample. We were given three samples that lacked protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used included
