exercises‚ it uses two types of fuel‚ carbohydrates‚ and fatty acids. At the beginning of exercise the main source of fuel is carbohydrates‚ however the duration of the exercise progresses the carbohydrates deplete and fatty acids are needed to maintain the exercise. The type of fuel being used can be seen in the ratio called‚ respiratory exchange rate‚ or RER. An RER of 0.7 means that carbohydrates are being used for fuel‚ and a ratio of 1.0 means that only fatty acids are being used for fuel; of course

This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

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
Premium Glucose Carbohydrate Disaccharide
Glucose is a form of energy derived from carbohydrates. All living organisms requires energy to live and thrive. When glucose is ingested it is transported through the circulatory system by the various tissues and organs. This glucose will be used by the muscular and nervous system to complete day to day task. If the body is not in need of glucose it will be stored in the form of glycogen for a later date. The entire process starts with carbohydrates‚ for this paper we will be tracing the path of

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

namely carbohydrates and lipids. Carbohydrates‚ which have the empirical formula (CH2O)n‚ acts as the predominant source of metabolic energy in muscle cells during exercise. They are stored in the liver and muscle cells as glycogen which is a branched polymer. Lipids mainly exist as triglycerides‚ which are made up of three fatty acids joined to one glycerol molecule‚ and are stored in adipose tissue. However‚ lipids exist as ketone bodies when in excess.
