Acetyl

Histone Deacetylase Inhibitors. Histone deacetylase (HDAC) inhibitors are responsible for inhibiting histone deacetylase enzymes, which work to remove acetyl groups from histones. The overexpression of HDACs is responsible for many cancers such as prostate, colorectal, breast, lung, liver, and gastric cancer. Currently, four drugs are FDA approved to function as HDAC inhibitors: Vorinostat (2006), Romidepsin (2009), Chidamide (2015), and Panobinostat (2015). Vorinostat is a linear hydroxamic…

For all organisms, prokaryotes and eukaryotes, they all must regulate the specific genes that are expressed at any given time (Campbell 365). Each organism continuously turn on and off genes in response to external and internal environmental signals. The regulation of gene expression is especially important in multicellular organisms since it is essential for the different types of cell to have their own cell specialization (Campbell 365). In order for each cell to do it’s given role, they each…

Chitin is a linear polysaccharide, with β-(1-4)-linked N-acetyl-D-glucosamine. Found in the exoskeletons of crustaceans (crab, shrimp, lobster, insects) & molluscs, as well as the cell walls of algae and fungi, chitin is the second-most naturally abundant polysaccharide after cellulose [1, 2]. Chitin occurs naturally in the polymorphic forms: α, β and γ. The α-polymorphic form of chitin is the most abundant in nature, present in the strong exoskeleton of crustaceans [6]. α-Chitin forms tightly…

It is also conceivable that, at lower pH, depurination can occur via protonation of the purine nucleobase at both N1 and N7. The presence of the 2′-OH has a significant effect on the nucleoside’s susceptibility to depurination. For example, guanosine and adenosine are more resistant to depurination compared to deoxyadenosine and deoxyguanosine. Deoxyadenosine itself depurinates 1200 times faster than adenosine (York, 1981). Interestingly, N-acyl-protected purine nucleosides (particularly…

approach is creating new routines making sure the individual has lots of emotional support. Antioxidants have also worked efficiently to treat Alzheimer’s. Cobalamin and Acetyl L-carnitine are some of the many antioxidants available. Cobalamin is a vitamin that in some cases has showed to improve memory and mental function. While using Acetyl L-carnitine has brought different results. “Some studies have indicated that 2–3 g daily slows the progression of AD in patients who developed the disease…

CO2 fixation is a process in which inorganic carbon is converted into organic carbon that can be used in other pathways to synthesize macromolecules. The Calvin-Benson-Bassham (CBB) pathway is often utilize by photoautotroph, photoheterotroph, and lithoautotroph for CO2 fixation. The CBB pathway is a cyclic pathway that occurs in 3 stages, the carboxylation phase, follow by the reduction phase, and then the regeneration phase. In the carboxylation phase, a 5 carbons compound called ribulose…

PURPOSE To determine how germination and temperature of environment effect respiration rate of seeds. BACKGROUND INFORMATION Cellular Respiration: Is the controlled release of energy from organic compounds in cells to form ATP. Sugar + Oxygen → Carbon dioxide + Water + Energy (ATP). In eukaryotic organisms, respiration occurs to maximize ATP production; this is contrary to anaerobic respiration, which occurs during the absence of a ready supply of oxygen (mostly in prokaryotic organisms).…

the course of the disease (Advokat et al., 2014). Some of the drugs for the treatment of Alzheimer’s disease focus on inhibiting the enzyme that breaks down acetylcholine in the synapse called acetyl cholinesterase inhibitors (Advokat et al., 2014). Donepezil, galantamine, and rivastigmine are examples of acetyl cholinesterase inhibitors (AChE-Is) that are currently prescribed to patients suffering from Alzheimer’s disease (Hansen et al., 2008). Side effects associated with these AChE-Is include…

Introduction Microbes are essential to everyday life. Going from the basic food we eat to biogeochemical cycles, if we didn 't have biogeochemical cycles we would no longer have any of the resources that we have now; for example, there is plenty of nitrogen in the atmosphere but it 's all not available until it has been fixed, and that is when the microbes come in and changes the nitrogen in a way that is usable. Humans come in contact with microbes every day there is never a time there are…
