contraction. With the exception of catalytic RNA molecules‚ or ribozymes‚ enzymes are proteins. The ability to assay the activity of specific enzymes in blood‚ other tissue fluids‚ or cell extracts aids in the diagnosis and prognosis of disease. Deficiencies in the quantity or catalytic activity of key enzymes can result from genetic defects‚ nutritional deficits‚ or toxins. Defective enzymes can result from genetic mutations or infection by viral or bacterial pathogens (eg‚ Vibrio cholerae). Medical

There are cases in which it’s been seen in teenagers and adults but that is due to a deficiency in an enzyme called pyruvate dehydrogenase and is not apart of this research. Leigh’s disease

response to ACTH‚ secrete glucocorticoids‚ in particular cortisol. In the peripheral tissues‚ cortisol is converted to cortisone by the enzyme 11-beta-steroid dehydrogenase. Cortisol has much greater glucocorticoid activity than cortisone‚ and‚ thus‚ cortisone can be considered an inactive metabolite of cortisol. However‚ 11-beta-steroid dehydrogenase can catalyze the reverse reaction as well‚ and‚ thus‚ cortisone is also the inactive precursor molecule of the active hormone cortisol. Cortisone is activated

Citric acid cycle From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search [pic] [pic] Overview of the citric acid cycle The citric acid cycle — also known as the tricarboxylic acid cycle (TCA cycle)‚ the Krebs cycle‚ or the Szent-Györgyi-Krebs cycle‚ [1][2] — is a series of enzyme-catalysed chemical reactions‚ which is of central importance in all living cells that use oxygen as part of cellular respiration. In eukaryotic cells‚ the citric acid cycle occurs in the matrix of the mitochondrion

The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help
