Effect of a factor on the activity of an enzyme Research Question: How does pH effect the activity of the enzyme amylase and the hydrolysis of starch? Hypothesis: Amylase is an enzyme that acts on starch. pH is capable of altering the structure of the active site centre in the enzyme leading to denaturation. At each pH, the enzyme activity would be relatively different. Ideally the optimum pH is 6.0 when the enzyme works best and the fastest, however if the pH is higher or lower the hydrolysis

E-Z notation From Wikipedia, the free encyclopedia Jump to: navigation, search E-Z notation, or the E-Z convention, is the IUPAC preferred method of describing the stereochemistry of double bonds in organic chemistry. It is an extension of cis/trans notation that can be used to describe double bonds having three or four substituents. Following a set of defined rules (Cahn-Ingold-Prelog priority rules), each substituent on a double bond is assigned a priority. If the two groups of higher priority

Although, when a person turns to using substances, it is a choice that is made by the person. When a person decides to use substance the person may have turned to a chemical substance to ease an emotional or physical pain, or explore as an experimental experience to discover alternative realities (Doweiko, 2015). When a person consumes a chemical substance the substance can then pass though the brain barrier, therefore, releasing the feel good endorphins in the brain to achieve a feeling of euphoria. However

CHAPTER 15 ORGANIC COMPOUNDS AND THE ATOMIC PROPERTIES OF CARBON 15.15 a) Octane denotes an eight carbon alkane chain. A methyl group (–CH3) is located at the second and third carbon position from the left. CH3 CH3 CH CH CH2 CH2 CH2 CH2 CH3 CH3 b) Cyclohexane denotes a six-carbon ring containing only single bonds. Numbering of the carbons on the ring could start at any point, but typically, numbering starts at the top carbon atom of the ring for convenience. The

------------------------------------------------- Enzyme From Wikipedia, the free encyclopedia (Redirected from Enzymology) Enzymes /ˈɛnzaɪmz/ are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.[1]:8
