of synthesis: 1- In pancreas: Synthesis of taurine in the mammalian pancreas occurs through the cysteine sulfinic acid pathway. First‚ in this pathway is oxidation of cysteine sulfahydryl group to sulfonic acid‚ this oxidation is catalyzed by the enzyme cysteine dioxygenase. In turn‚ cysteine sulfonic acid is decarboxylated to hypotaurine by sulfonoalanine decarboxylase. It is not well known whether hypotaurine is then enzymatically or spontaneously oxidized to taurine. 2- in CNS: Biosynthesis of

INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

then converted to ethylene by ACC oxidase (ACO)‚ a member of the oxygenase/oxidase superfamily of enzymes6.The ACS plays a central role to regulate ethylene production through changes in ACS gene expression levels and the stability/activity of the enzyme. ACS proteins can be divided into 3 groups (type-1‚ 2 & 3) based on their C-terminal domain and the presence of phosphorylation sites. Type-1 and -2 ACS isoforms contain phosphorylation sites for kinases‚ but type-3 lacks of the phosphorylation sites

the theory is the force on any flat surface is the average pressure acting on the submerged surface multiplied by the area of the submerged surface. F = ρgXA Where: ρ = water density g = acceleration due to gravity X = vertical distance from free surface to centroid of A We know that the magnitude of the distributes force F‚ which may be considered as a small series of small forces spread over the submerged surface. The sum of the moments of all these small forces about any point must be

Investigating the Enzymatic Activity of Catecholase through Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration University of Alabama at Birmingham Burgess‚ B.N. Introduction: Background Enzymes are macromolecules that act as catalysts in living organisms by speeding up chemical reactions without being changed or destroyed by the reaction (Campbell and Reece‚ 2008). Enzymes are able to speed up the rate of a chemical reaction by decreasing the activation energy during the reaction

Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus

Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate
