University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

nigrum possesses various compounds that are responsible for diverse activities. The major active components are glycoalkaloids‚ glycoproteins‚ and polysaccharides. It also contains polyphenolic compounds such as gallic acid‚ catechin‚ protocatechuic acid (PCA)‚ caffeic acid‚ epicatechin‚ rutin‚ and naringenin. The glycoalkaloids include solamargine‚ solasonine‚ and solanine that belong to the tropane group of compounds. Jain R‚ Khattak JZ 2012 Solanine’s function and activity has been extensively

Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme converts them into different molecules‚ the products. Enzymes are extremely selective for their

cells are subjected to higher temperatures‚ different components of the bacterial cell including phospholipids‚ nucleic acids‚ and proteins become denatured resulting in the disruption of tertiary structures (Nadwell 1999). In comparison‚ when temperatures decrease below the optimal temperature‚ the affinity for substrates of bacterial cells also decreases‚ due to the hardening of lipids within the membrane (Nadwell 1999). This further causes a

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)
