Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

The Trans-Pacific Partnership Agreement (TPPA) is the biggest trade agreement in history‚ making up about 40 percent of the global economy with a projection of almost $30 trillion. Other than being the biggest trade agreement‚ TPPA is described as a secretive and multinational ‘free trade’ agreement lead by United States. The agreement is currently‚ be negotiated between 11 countries‚ which are Malaysia‚ New Zealand‚ Australia‚ Brunei‚ Chile‚ Peru‚ Singapore‚ Vietnam‚ Japan‚ Mexico‚ and Canada. The

members of that species available to reproduce. Question #10 When comparing a ban on trans-fat to a ban on cocaine the difference rests in the supply and enforcement of the two. Trans fat is produced and supplied in a regulated and controlled market where as illicit drugs are regulated by a cartel. The two different markets would explain which ban would be easier to enforce. Considering the fact that trans-fat is not produced or sold on the

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

Psalm 23 and The Sermon on the Mount are both so similar and different messages about God. Psalm 23 and The Sermon on the Mount both talk about all the good things God can do to all of the of the people who are nice and fair around the world. Both the psalm and the sermon‚ mention how everyone will always have something good and how we should never fear anything because God will always be accompanying us in our good and bad moments. However‚ the main difference is how they are being narrated. Psalm

has already a wide amplitude of ions‚ where the addition of sodium chloride just increases the overall ions in the solution‚ hence more conductivity; since electrons are moved through ions. What I found through three attempts of finding the average conductivity of HCL is 4978.66666667 µS/cm. Which comparably to the 2 different solvents I chose‚ is the most conductive. This is because once again‚ HCL has a wide amplitude of ions and is a strong acid. Where comparing to the conductivity of distilled

Sodium thiosulfate is safe to handle and store‚ but if it is mixed with an acid‚ a reaction happens. When dilute sodium thiosulfate is mixed with an acid‚ solid sulphur is made‚ which makes the solution appear cloudy. The reaction also makes small amounts of toxic sulphur dioxide gas. You will choose one factor and investigate this factor’s effect on the rate of reaction between sodium thiosulfate and dilute hydrochloric acid.
