Known as resomation‚ or water cremation‚ it speeds up the natural decomposition process through alkaline hydrolysis. Once the procedure is complete‚ survivors are given around 200 gallons of fluid with some bone fragments. This solution can be used for lawn fertilization‚ offering a truly “green” way to go out. Burial One of the major problems with burials

Lab 8 - Chemical and Physical Processes of Digestion (p.105) Introduction: In this lab‚ I will study how digestion of carbohydrates‚ proteins‚ and fats occurs. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Enzymes (p. 105) – Speed up chemical

Bioethanol Fuel 3 Ethanol can be produced from biomass by the hydrolysis and sugar Fermentation processes. Biomass wastes contain a complex mixture of carbohydrates polymers from the plant cell walks known as cellulose‚ hemi cellulose and legin. In order to produce sugars from the biomass is pre-treated

groups‚ a hydroxyl group (-OH) and an ester group (-COOCH3). In salicylic acid the ester group is replaced by a carboxylic acid group (-COOH). The process that causes the ester group to be replaced by a carboxylic acid group is an example of ester hydrolysis under strongly basic conditions. The following is a mechanism for the synthesis of salicylic acid: Procedure* - See Attached Data and Observations – Filter Paper : 0.74 g Boat: 2.35 g Final Weight of Product: ___________g

ulmaria)‚ a wild flowering plant that grows on riverbanks over much of Europe. Raffaele Piria [an Italian chemist] then working at the Sorbonne in Paris split salicin into a sugar and an aromatic component (salicyladehyde) and converted the latter‚ by hydrolysis and oxidation‚ to an acid of crystallized colorless needles‚ which he named salicylic acid. (1838). the problem was that salicylic acid was tough on stomachs and a means of ‘buffering’ the compound was searched for. The first person to do so was

D_____ J_____ CARBOHYDRATES LAB May 22‚ 2013 Pre-lab Questions 1. The water in test tube No. 1 is a negative control. No reaction is expected to occur because water is not a carbohydrate. Reaction by a negative control is evidence of contamination. 2. The color changes expected for positive test results are Benedict’s test: orange to brick red Tollen’s test: metallic silver Starch iodine test: blue-black 3. Identify each of the samples in Part 1 as monosaccharide

depends on various factors‚ such as temperature‚ pH‚ cofactors‚ activators and inhibitors. Invertase is an enzyme which is usually found in plants. It acts as a catalyst for the hydrolysis of sucrose. Sucrose is a disaccharide composed of glucose and fructose linked by a glycosidic bond. When this bond is cleaved in a hydrolysis reaction‚ an equal amount of glucose and fructose. Invertase is a significant enzyme because glucose is an important product of photosynthesis. Invertase is also used in the

During which phase of the cell cycle does DNA duplication‚ or replication‚ take place? – interphase When a double helix of DNA is replicated‚ two complete helices are formed. Together‚ these helices are called sister __________. – chromatids During which phase of mitosis do sister chromatids line up at the center of the cell? – metaphase During which phase of mitosis do the sister chromatids move apart? – Anaphase During which phase of mitosis do nuclear envelopes and the nucleoli reappear?
