Weak acid

proteins work because they are essential to our health. Without proteins our bodies would not be able to form vital bodily components such as enzymes, and antibodies. A protein is defined as “large molecules consisting of one or more chains of amino acids in a certain order, determined by the base sequence of nucleotides in the base sequence of nucleotides in the DNA coding for the protein” (Medicine net). Insulins formula is C254H377N65O75S6 and its molecular mass is 5808 Da. When the protein…

bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid. When an acetic acid and baking soda (sodium bicarbonate) are mixed together, three new chemicals are formed, Water (H2O), carbon dioxide (co2), and sodium acetate (C2H3Na02). When one of the three chemical atoms breaks off, it creates the chemical reaction. Vinegar Vinegar is an acetic acid, which is produced by the fermentation of ethanol by acetic acid bacteria (Google.com/vinegar). For the purpose of the experiment,…

Effect of Acid Rain on Wisconsin Fast Plants Introduction Acid rain has become a large environmental problem around the world. This chemically potent precipitation is incredibly common in large metropolitan cities where pollution and smog are prevalent. Acid rain has been known to diminish plant growth or completely kill off populations within the contracted areas of these large cities. In addition to effecting plants, it has also been determined that the pollutants in acid rain, such as heavy…

1. Given the following amino acids, explain where they would be found in the tertiary structure of a protein and WHY (lack of explanation/incorrect explanations will NOT receive full credit; assume living system of pH = 7.4). Arg Phe Pro Glu His Ala Tyr Val Cys Arginine: This is a charged amino acid that is extremely hydrophilic. It is hydrophilic because while it has an aliphatic side chain that is hydrophobic, it also has two groups where a positive charge resonates between the two…

Explain the importance of hydrophobic interactions in tertiary structure # introduction : Proteins are organic compounds that made up of building blocks , called "amino acids." There are around 20 common types of amino acids. Nine of them are viewed as "essential " in the fact that the body can't make them, so they should be provided by eating healthy. A polypeptide chain is a chain of amino-linked together by peptide bonds. The foundation of the polypeptide is given by the repeated…

A protein has a precisely defined amino acid sequence which gives rise to its three dimensional structure which is essential to the protein’s function. These amino acids interact with one another to produce a specific folding pattern that produces the conformation of the protein. When one looks at the progression a protein makes in its folding complexity, it is clear that the folding is driven by the amino acid sequence alone. To understand this concept it is best to start with the primary…

secondary, tertiary, and quaternary structures of proteins, membranes, and nucleic acids are critical in understanding biological processes. Nucleic acids and proteins have analogous primary, secondary, and tertiary structures. Proteins and membranes are the only macromolecules that form tertiary and quaternary structures. PRIMARY STRUCTURE The protein primary structure is composed of 20 varying amino acid subunits. Amino acids…

Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…

What is acid rain? Acid rain is a form of deposition in which chemicals with an acidic pH level are taken out of the atmosphere through precipitation. When we pollute the air by burning fossil fuels, we create different chemicals that end up in our atmosphere. A few of these have chemical reactions with the water in clouds, and form (depending on the chemical) sulfurous and nitrous acids. When it rains, this acid is taken back to the ground. While pure water has a neutral pH level of 7,…
