Running Head: Factors Affecting Citric Acid Production by Aspergillus niger Factors Affecting Citric Acid Production by Aspergillus niger Ong Chia Swing‚ Student. Nilai University 1. Introduction Citric acid is a natural preservative or conservative that is used to add an acidic‚ sour taste to foods and beverages. In the context of biochemistry‚ the conjugate base of citric acid which is the citrate plays an important role as an intermediate in the citric acid cycle which occurs in the metabolism

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be

these substances we humans dearly love‚ discoveries which has benefitted us in terms of our health. The purpose of this investigation is to find out how stable unsaturated fats are compared to saturated fat when these are exposed to great heat-energy and more specifically water. By this information‚ this can be used as a tool by understanding how certain fats or oils behave at certain conditions and the chemistry behind it‚ and improve our awareness when it comes to selecting the “right” type of

reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult

Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due to the percent error that was calculated to be approximately 94.8 %. This value significantly shows how close the
