Maillard reaction

1. 6 cleaned and dried conical flasks were collected and safely transported to the experimental table. 2. A black marker was used to mark a black cross on a white sheet of paper. This was to help with measuring the time (dependent variable). 3. A thermometer was placed on the table to measure the room temperature. 4. 0.15mol/L sodium thiosulphate solution (Na2S2O3) and 3mol/L hydrochloric acid (HCL) were poured into two separate 50 ml beakers, and the two beakers were transported to the…

Normal standards for specific gravity are as typically as follows: 1.000 to 1.030 is a normal specific gravity, 1.001 after drinking excessive amounts of water, more than 1.030 after not drinking very many fluids and concentrated after receiving an antidiuretic hormone (ADH). Max’s urine concentration varied in concentration each time he was tested. The first test showed that his urine was a pale yellow which was an indication that he was hydrated. The second test showed the concentration to be…

Introduction Density measures the volume that a given amount of mass takes up. Usually, density has grams per unit volume as a unit. To find the density of an object, the object has to be measured and its mass has to be divided by its volume. Often times, density is used to identify substances, since different elements have specific densities. This experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance. If the procedure is…

formation, temperature change, precipitate formation, odor, and change in acidity. In the hot and cold pack experiment we found it to be a chemical reaction An exothermic reaction is when the substance releases heat energy. An endothermic reaction is when the substance absorbs heat energy. In our experiment we created a cold pack. We indicated that the reaction for this experiment would be exothermic. We think this because exothermic is releasing the heat which would make it cold. In our lab…

In this lab there was 2 objectives which where to recognize when a chemical reaction has occurred and practice collecting detailed observations in the laboratory using proper scientific terms. Reaction set #1 (1a) place approximately 1 ml of 0.1 M Pb (No3)2 solution into a test tube. Then sequentially add drops of 0.25M k2CRO4 solution until you see evidence of a chemical reaction. The products of this reaction are aqueous KNO3 and solid PbCrO4. (1b) place approximately I ml of .1M Pb (NO3)2…

The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster. Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931. In 2006,…

Which means whenever two chemicals react together you can’t lose any of the atoms. So lets say you have a chemical reaction of H2O + NaCl, which is water and table salt, it could go to NaH2 +ClO, but it can’t lose any of the atoms it started with or gain any new ones. The Law of Conservation of Mass governs how a chemical reaction happens because if the chemical reaction of water and table salt happened and it lost a hydrogen atom, it could make something completely different and the physical…

Enzymes are proteins that are a efficient catalyst for a biochemical reaction. It’s responsible to speed up reaction by having an alternative pathway of low active energy. In a simple cell it can be found 2000 different enzymes, each one of these have the ability on catalyzing a different reaction. Each of the enzyme found are responsible on having a reaction occurring in the cell. In this certain reaction in the cell, the cell will tend to make poisonous chemical that could be harmful to the…

Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

in terms of shape and size but are conventionally spherical or oval shaped, 0.5µm in diameter and around 0.5-5µm in length. The internal lumen of a lysosome contains enzymes that catabolically break down biological macromolecules via hydrolysis reactions (insertion of a water molecule that breaks intramolecular bonds). Enzymes include; proteases, ribonucleases, deoxyribonucleases – all defined as hydrolases. Such enzymes are synthesised at ribosomes found on endoplasmic reticulum, and are…
