Enzymes are specialized proteins that act as catalysts. Enzymes are a key part of many biological processes because they are capable of lowering the activation energy of a chemical reaction. By lowering the activation energy enzymes are able to speed up reactions allowing for multiple chemical processes to occur at a faster rate in many living organisms. Enzymes work by binding to specific molecules called substrates. The enzyme observed in this experiment was amylase and its…
today are caused by pollution or contamination through inorganic compounds so it is imperative that scientists and researchers known how to physically and chemically identify these substances. The testing of inorganic substances to determine the chemical makeup is present in many different types of research. Monthon Thanutamoayong is a scientific researcher who focused on the identification of inorganic pollutants in drinking water through nanofiltration. Through this type of testing, the…
Carbohydrates have the following basic composition. They are molecular compounds made from three elements: carbon, hydrogen and oxygen. Monosaccharides are simple sugars with multiple OH groups. Based on number of carbons 3, 4, 5, 6, a monosaccharide is a triose, tetrose, pentose or hexose respectively. Disaccharides are condensation products of two monosaccharide units; examples are maltose and sucrose. A disaccharide is 2 monosaccharides covalently linked molecule. Polysaccharides are polymers…

Measurement of glutathione
Glutathione (GSH) is a ubiquitous tripeptide which serves several vital functions including detoxifying electrophiles, scavenging free radicals and providing a reservoir for cysteine. The sulfhydryl group of GSH reduces 5-5'-dithiobis (2-nitrobenzoic acid) (DTNB) and form the yellow colour product 5-thio-2-nitrobenzoic acid (TNB)21. Measurement of the absorbance of TNB at 412 nm provides an accurate estimation of GSH in the sample. Figure 7.

Exp 12: Thermodynamic Analysis of Chemical Equilibria
The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…
III )Krebs cycle
The Krebs cycle consists of five major points .
There is in firstly the general overwiew of cellular respiration and in secondly mitochondrie structure then Acetyl-Coa wich contains Production and possible fates then Krebs Cycle wich contains reactions and regulation and finally Glyoxylate cycle.
For the general overwiew of cellular respiration we will talk about cellular respiration.
Cellular respiration is an aerobic phase of catabolism in which organic fuel molecule are…
Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy
In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution . The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy . A change in…
The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…
