Proteins have various functions such as making and breaking chemical bonds‚ transport‚ movement‚ signaling‚ regulation and metabolism (cellular process). Peptide Bonds are important while discussing proteins. Peptide Bonds are covalent bonds that join 2 amino acids‚ amino acids are also proteins monomer. Next are Carbohydrates. Carbohydrates incorporate Carbon‚ Hydrogen and Oxygen in a 1:2:1 ratio. They provide short term energy

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result

Smithsonian Laboratory Early Atmosphere 1. How abundant was oxygen in the early atmosphere? The earth’s early atmosphere contained only small amounts of free oxygen‚ produced by the reaction of water vapor with sunlight. The oxygen rich atmosphere that developed later and on which oxygen breathing life now depends was result of the origin and spread of organisms capable of photosynthesis. 2. What evidence do scientists have that the oxygen content of our atmosphere has increased since the earth’s

CH201L S.Y. 2014-2015 Analysis of Oxygen-Bearing Organic Compound 2 BS Chemistry‚ College of Science‚ University of Santo Tomas Espana‚ Manila Philippines 1015 Abstract An unknown sample was given along with five standards to test the presence of oxygen in the sample. The unknown sample underwent five different chemical analysis namely Dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test‚ and Iodoform test. Each test will determine if the unknown sample will have the same reaction as

When 31 g of phosphorus reacts with oxygen‚ 71 g of an oxide of phosphorus is the product. What mass of oxygen is needed to produce 13 g of this product? 31g + x = 71g 71g - 31g = 40g oxygen This means that in

a beneficial therapy for children with Cerebral Palsy? Background: Hyperbaric Oxygen Therapy (HBOT) is being promoted as a new therapy for children afflicted with cerebral palsy. It is being utilized by several specialized medical centers in the US‚ Europe and Canada. The rationale behind this therapy is inhalation of pressurized pure oxygen within a hyperbaric chamber‚ results in higher levels of dissolved oxygen within the blood (Liptak‚ 2005). Over 15 studies have been conducted to determine

(Figure 1). For the next test‚ Dissolved Oxygen‚ we also created a bar graph to compare the values for the control and experimental groups. These results came in as statistically significant too‚ as the p-value was very low at .004. As for the overall mean values of the two groups‚ we found that the control group was oversaturated with oxygen at 102.78% while the experimental group was also slightly oversaturated at 101.55%.
