general features of condensation and hydrolysis reactions. Condensation reactions link monomers together. The same reaction is repeated many times to make a polymer and is used to link subunits in lipid molecules. In condensation reactions a water molecule is released‚ a covalent bond is formed and a larger molecule is formed by the bonding together of smaller molecules. When a larger molecule splits this is called a hydrolysis reaction. In hydrolysis reactions a water molecule is used‚

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest

Determination of the Rate Constant for a Chemical Reaction Department of Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation

Abstract: Saponification is an esterification process that is used to make so from the hydrolysis of fats and oils. This process have the glycerol molecule‚ and a sodium carboxylate salt in most case sodium stearate being formed‚ however this salt depends on the base being used. In the experiment 23ml of vegetable oil was mixed with 20ml of ethyl alcohol along with 20 ml of 25% sodium hydroxide in a 250-mL Erlenmeyer flask. The content was then heated on a water bath whilst gently mixing with

Secondly‚ I ran a gram stain and found a gram positive‚ cocci bacterium (Table 1‚ Figure 2). Third‚ I ran a catalase test in which was negative (Table 1). From here‚ I determined a starch hydrolysis test would be necessary to distinguish between different bacteria. The result was negative (Table 1). After starch hydrolysis‚ I ran an MSA plate‚ hoping it would give a clear answer as to what the bacterium’s identity was. This result was positive (Table 1‚ Figure 3). The fifth test I ran on unknown A was

proteins by a hydrolysis reaction‚ it does this by adding a molecule of water to a peptide bond. Although the hydrolysis reaction is thermodynamically favoured in the absence of a catalyst the half-life for a typical hydrolysis reaction by a protease is between 10 and 100 years‚ needless to say it is extremely slow1. Though this is true peptide bonds are hydrolysed within milliseconds in the body in the presence of catalysts. The kinetic stability of chymotrypsin which gives it hydrolysis resistance

Gram Negative Unknown Lab Report Abstract The Unknown Gram Negative bacterium inoculated in a Tryptic Soy broth medium was randomly selected from a group of other unknowns. In order to identify this unknown the seven different types of biochemical tests will be conducted on this unknown bacterium to identify it out of 6 possible bacteria; Escherichia coli(E. coli)‚ Enterobacter aerogenes (E.aerogenes)‚ Klebsiella pneumoniae (K.pneumoniae)‚ Proteus mirabilis(P.miranilis)‚ Pseudomonas aeruginosa(P
