1.0 Title Determination of Protein Content Using Kjedahl and Titration 2.0 Introduction Proteins are polymers. They are the source of dietary amino acids and are used for growth and maintenance of living systems. They are costlier sources of energy compared to carbohydrates and fats and hence the human body utilizes proteins mainly for biosynthesis rather than as an energy source‚ though the energy yield is 5 kcal/g of protein. Twenty different types of amino acids occur naturally in proteins

Determination of Calcium ions in milk using titration. Background Calcium is a mineral which is essential to the human body. In fact 1.5% of the human body is made up of calcium‚ and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions‚ for example blood clotting. It also partakes in the regulation of the hearts rhythm. Lack of the crucial mineral can result in the build up of cadmium and lead‚ both of which are toxic. along

Determination of An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96‚ and the pKa’s found experimentally were 2.0‚ 4.0‚ and 9.85. The accepted pKa values were found to be 2.10‚ 4.07‚ and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚

He formed our world today along with the people in it‚ he began his works long before all of us were made. While reading “From Preface to God’s Determination‚” Edward Taylor captures many elements throughout the poem that represents a theme‚ imagery‚ and similes. The theme is the central idea in a piece of writing. In “From Preface to God’s Determination‚” the message of the poem is God’s handiwork on everyday life.

Gravimetric Analysis: The Determination of Phosphorus in Plant Food Gravimetric analysis is a quantitative (i.e. how much?) method of classical analysis. The element to be determined is isolated in a solid compound of known identity and definite composition. The mass of the element that was present in the original sample can be determined from the mass of this compound. Plant foods contain three essential nutrients that are not readily available from soils. These are soluble compounds
