Peroxisome

Adrenoleukodystrophy (ALD) is a condition which affects the ability of adrenal glands to produce adrenaline and myelin, which insulates the nerves in the brain and spinal cord. This diminishes the ability of the brain to communicate effectively with the rest of the nerves. This condition was initially identified in the early 1900s and was originally called Schilder-Addison disease (2). The cause of this condition originates in the peroxisomes, which are tiny structures in the cell which assist cells in the fatty acid break down process. When peroxisomes cannot perform the breakdown of Very Long Chain Fatty Acids (VLCF), complications will eventually appear; leading to the accumulation of VLCF in the adrenal organs. According to Thomas C.…

Cells contain organelles they aren’t touched basis on, that also play a very important role into the cell as far development goes. Many of the organelles operate off of other to maintain its specific duties with the human body. One in particular are considered to be peroxisomes. Peroxisomes have digestive enzymes in relations to lysosomes, but they have special bodies that allow it to work in low level regions in which wouldn’t be supported elsewhere inside of the specific cell. Peroxisomes…

Peroxisomes and Adrenoleukodystrophy Adrenoleukodystrophy, or ALD, is a rare genetic disorder in which the myelin sheath surrounding nerve cells in the brain breaks down, and the adrenal gland progressively loses function.(medical dictionary. Myelin sheaths coat nerves to speed up and strengthen neural impulses. If the myelin malfunctions, many neural messages will not do what they should. ALD primarily affects boys and men. It is extremely rare, only 1 in every 100,000 people are afflicted.…

Peroxisomes serve to produce hydrogen peroxide through oxidation, as well as break it down by converting it to water, or using the hydrogen peroxide to oxidize other organic compounds. They also produce energy by metabolizing fatty acids (Cooper, 2000). Peroxisomes execute various metabolic functions and create hydrogen peroxide as a byproduct from the process of oxidation. However, since the hydrogen peroxide created by the peroxisome is toxic, the organelle also produces an enzyme called…

Hans Zellweger, a Swiss American professor of pediatrics and genetics at the University of Iowa in the mid-1960s described the familial disorder among siblings that was later named after him for the recognition of his discovery, the Zellweger Syndrome. Peroxisomes are cell structures that break down toxic substances and synthesize lipids (fatty acids, oils, and waxes) that are needed for cell function. Peroxisomes are what is needed for normal brain development and its function and it’s what…

Rare peroxisomal biogenesis disorder RCDP1, is a genetic disease diagnosed in infants and inherited in an autosomal recessive pattern. The disease is caused by a monogenic nonsense or missense mutation in the PEX7 gene of humans, encoding the Pex7p import receptor protein responsible for transporting PTS2 proteins and enzymes from the cytosol to the matrix of the peroxisome. Affected individuals are significantly impaired and do not live longer than a decade, displaying severe learning, growth,…

spectrometry imaging revealed altered spatial distribution of many lipids in tissue sections of Lcn2-deficient mice or WT mice fed an MCD diet. Significant changes to m/z signal intensities for various sphingomyelins, triglycerides, and glycerophospholipid species were observed, including elevations of phosphatidylinositol diphosphates and -triphosphates in MCD-fed mice, regardless of LCN2 status. Interestingly, two arachidonic acid containing glycerophospholipids were increased in…

Both also contain similar membranes, cytosol, and cytoskeletal elements. The functions of these organelles are extremely similar between the two classes of cells (peroxisomes perform additional complex functions in plant cells having to do with cellular respiration). However, the few differences that exist between plant and animals are very significant and reflect a difference in the functions of each cell.Structurally, plant and animal cells are very similar because they are both eukaryotic…

Adiponectin is a cytokine exclusively produced and secreted by adipocytes. In mice, adiponectin decreases hepatic lipogenesis and increases FFA oxidation. In humans, several studies have shown an inverse correlation between adiponectin levels in the blood and hepatic insulin sensitivity as well as fat content in the liver. Adiponectin is a cytokine which acts as an anti-steatotic factor in both muscle and hepatocytes, probably by activating Peroxisome proliferator-activated receptor gamma…

due to its capability of decomposing hydrogen peroxide, an extremely dangerous and harmful oxidizing agent to water and molecular oxygen. Conversion of hydrogen peroxide: 2H2O2 → 2H2O + O2 Catalase can be found in a cell organelle known as the peroxisome. Peroxisomes are located in animal cells, which are in charge of the oxidation of fatty acids, and synthesis of cholesterol and bile acids. Due to the oxidation of fatty acids, hydrogen peroxide is formed by white blood cells in order to kill…
