Tartaric acid

Results showed that the basic amino acids for sea bass fillets were glutamic acid, aspartic acid and lysine. The amount of methionine, tyrosine and histidine were lower than the other amino acids. Similar to the data obtained by Ozden and Erkan (2008). Fish are quite rich in lysine (Ozden and Erkan, 2008) and other reported that the main amino acids in sea bass were aspartic acid, glutamic acid and lysine also, The changes in amino acid contents in fish muscle were affected by spawning…

Hot packs and cold packs are a useful item when it comes to treating injuries. Inside a pack is salt and a certain amount of water. When you break the pack, the salt mixes with the water causing a reaction that either increases or decreases the temperature. When these salts dissolve in the water it creates a reaction that is either endothermic or exothermic. Endothermic is the absorption of heat. This is when the pack gets hotter. Exothermic is the release of heat. This is when the pack gets…

experiment was to measure how much the pH changes when an individual adds a certain amount of acid or base to water, biological buffers, and other biological solutions. It is vital to study the changes in pH because a slight change in pH in an organism’s body can disrupt metabolism activities and even cause death. To accomplish the purpose of the experiment, an individual will add certain amounts of acid or base to water, biological buffers, or other biological solutions. pH is a measure to…

Fruit Spoilage Lab Abstract: The purpose of this lab is to see if lemon juice has an effect on fruit turning brown. When fruit is exposed to the air, it turns brown so the target of the lab was to try and prevent discoloration of the fruit. Using lemon juice and water, apples and bananas were tested to find if the chemicals really did prevent brown coloring from appearing on the fruit. With the lemon juice as the independent variable and the apples and bananas as the dependent variable, the…

Discussion of results: Multiple tests were done in order to identify and then confirm the identity of an unknown substance. The tests done to identify the compound included preliminary tests, solubility tests, and testing for anions and cations. In order to confirm the identity found, reactivity tests were then completed. The first test performed was a preliminary test that simply showed that the unknown compound was a powdery, white solid with no smell. A qualitative solubility test was…

(DeLoney-Marino CR, 2013) Vibrio Fischeri is a heterotroph and has the ability to be anaerobic and aerobic which was determined through genome sequencing and chemical assays. One of the ways in which it is able to grow anaerobically is by using mixed-acid fermentation. (Ruby et al. 2005) Vibrio Fischeri is also oxidase positive. Location: Vibrio Fischeri is found in shallow marine environments and has a symbiont relationship with certain squid and fish (see Figure 1). Vibrio Fischeri stops the…

Phosphorus is an element with the atomic number 15 and is described by the symbol P. Phosphorus was found in 1669 by a man named Hennig Brand. Brand was testing urine samples when he came across a weird substance now known as Phosphorus. Phosphorus is stored in the small intestine, but is mostly found in your bones. Phosphorus can be helpful in so many different ways. Phosphorus can be found in food such as meats, peas, and different types of dried beans. Phosphorus can also be used in fireworks…

Activity 2: Chemistry In a Bag With Chemistry In a Bag, students learn the difference between a physical change and a chemical change and how changes can either be endothermic or exothermic. Set-up: Each group of four students will need 1 canister filled with calcium chloride (CaCl2), 1 canister filled with sodium bicarbonate (NaHCO3), 1 dropper of phenol red, a set of measuring spoons, a measuring cup, a portion cup, four pairs of goggles and four sandwich bags. Make sure there are paper…
