an individual they deemed as a threat. In addition‚ these men have attempted rape‚ committed arson and exposed themselves in public. The abnormal behaviours exhibited by these men are linked to the gene responsible for the productions of monoamine oxidase-a‚ an enzyme which destroys neurotransmitters in the brain. This particular family study does seem to suggest that genetics play an important role in antisocial or criminal behaviour highlighted by the violence and aggression portrayed by the individuals

Monoamine oxidase (MAO) is a group of enzymes bound to the mitochondria; they regulate neurochemistry by degrading monoamine neurotransmitters. (Edmondson et al‚ 2004)15 Too much MAO activity is thought to be a cause of depression (Meyer et al‚ 2006)16; therefore MAOI’s

Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial

Its mechanism of action is the inhibition of xanthine oxidase‚ the enzyme responsible for the conversion of hypoxanthine to xanthine to uric acid. At therapeutic concentrations it does not inhibit other enzymes involved in purine and

Enzyme Inhibition Many drugs exert their action by inhibition of an enzyme activity in the body. If the activity of an enzyme is vital to the cell or organism‚ then inhibition may lead to death of the cell or organism. It is now possible to design new drugs which are enzyme inhibitors once a target enzyme has been identified. Types of Inhibitors A) Reversible Inhibitors: The effect of the inhibitor is instantaneous‚ and it can be removed from the enzyme by dialysis so that the enzyme activity

(DAG) and ceramides impair insulin metabolic signaling and prompt diabetic cardiomyopathy. In this regard‚ the increased DAG in cardiomyocytes impairs glucose metabolism through activation of protein kinase C (PKC) isoforms [24]. Ceramides are a family of bioactive waxy lipid molecules composed of sphingosine and a fatty acid [24]. Ceramide directly activates the atypical PKCs to phosphorylate and inhibit the insulin metabolic Akt/PKB signaling and thus inhibit GLUT4 translocation and insulin-stimulated

Acute Inflammation The survival of all organisms requires that they eliminate foreign invaders‚ such as infectious pathogens‚ and damaged tissues. These functions are mediated by a complex host response called inflammation. Definition of inflammation Inflammation is fundamentally a protective response‚ the ultimate goal of which is to rid the organism of both the initial cause of cell injury (e.g.‚ microbes‚ toxins) and the consequences of such injury (e.g.‚ necrotic cells and tissues)

Electrophoresis followed by the staining of the proteins will cause the enzymes‚ aldehyde oxidase‚ alcohol dehydrogenase‚ and malate dehydrogenase‚ to become visible‚ appearing as a set of different banding patterns. The banding patterns will dependent on the molecular form of the enzyme‚ indicating the genetic variation that can exist between
