In conclusion, various temperature levels do affect the glucose concentration level, of alpha-galactosidase, which is a product of Beano. The higher levels were actually found in the lower temperatures. Temperatures that were at 40, and 50 degrees Celsius had the highest glucose concentration levels at 25 minutes, which was 2.00%, while other temperatures such as 80 and 90 degrees Celsius were at 0.00% at 25 minutes, which is a major difference. However 30 and 70 degrees Celsius had a steady…

binding the oxygen. A hemoglobin consists of four sub units and therefore it can be termed as a tetramer. This tetramer is made of two dimers known as alpha-beta dimers. Therefore, in total hemoglobin is made up of two alpha monomers and two beta monomer. Each of these monomers makes a subunit of a hemoglobin. Each of these subunits is responsible of binding and transporting an oxygen molecule. Oxygen binds to the…

In the beginning of the movie, the professor mentions a “propulsive polymer”. We have learned about polymers in chapter twenty-four. We learned that a polymer is a large molecule made up of smaller molecules; which are monomers. Monomers are linked together. The monomers must have needed to be in a perfect combination to have such unique properties, to create flubber. This makes flubber seem to be a fantasy object.…

Plastic has been becoming more and more important since 1900’s and nowadays we cannot survive without it. In general, the major features of plastic are durability, light weight and low cost but these good properties also generate great problems to our environment. Current levels of use and disposal generate several environmental problems. Around 4% of crude oil is used as raw material for plastics and 3 to 4% extra are consumed to provide energy for manufacturing process. The major usage is…

altered by chemicals and structural changes and how the polymer is processed. Polystyrene is an additional polymer, which is a polymer in which the monomers simply add together with no other products formed1. Polystyrene has an array of chain lengths so there is no definite molecular weight of the compound1. Polystyrene is styrene added to a monomer. Styrene can be found in coffee beans, strawberries, and peanuts1. Polystyrene can be found in coat hangers, egg cartons, and plastic…

Introduction Many products including powders, drinks, and foods are marketed as having more protein in them than the average consumption. But is that statement actually true? Proteins are a type of amino acid. There are twenty known amino acids monomers. Monomers are molecules that can be bonded together to create something else known as a polymer. Every amino acid has to have three things, an amino group, a carboxyl group and a functional group that is special to itself. Something that is…

Direct Polycondensation The direct polycondensation has 3 main steps: 1. Removal of water. 2. Polycondensation of oligomer. 3. Melt condensation that makes PLA with high molecular weight. Direct polycondensation of lactic acid is the modest reaction that forms lactide simultaneously by the decomposition processes and it is not used for the large production of PLA [19-22]. Back in the days, the direct polycondensation was assumed as the reaction that produces inadequate polymers with low…

Alkaline phosphatase (AP) is a homodimeric enzyme complex that is commonly found in a wide range of organisms, from bacteria to all tissues of the human body. AP is a zinc metalloenzyme (1), in which metal ions play a key role in the regulation of catalytic activities and stabilization of enzyme-substrate complex. As proposed by Gettins and Coleman using NMR studies (10), each active site of AP comprises of three metal binding sites, which acknowledged as M1, M2, and M3. Two zinc ions bind to…

QXT2- Task 6 “No man is an island no man stands alone”, no entity on Earth can survive without interacting with abiotic factors. Organisms strive daily for survival. Their survival is predicated on receiving enough energy and nutrients to carry out metabolism and maintain homeostasis. Survival of a species is determined by the fitness of an organism within its environment and how successful it is at passing its genes on to its progeny. When examining the interactions that must be carried out…

aqueous solution of FeCl3 (1M) was added dropwise to the pyrrole solution. The oxidant to monomer ratio was 1:1. The polymerization was carried out for 3h under constant stirring at ~ 0°C. This mixture was allowed to settle for 24h to ensure complete polymerization. The product obtained was filtered under reduced pressure. The product was washed with distilled water successively to remove the unreacted monomer, oxidant and dried under vacuum at room temperature to a constant…
