There is ongoing research on this topic, but there is a theory known as inhibition theory. See this from here: Directed attention fatigue occurs when a particular part of the brain’s global inhibitory system is overworked due to the suppression of increasing numbers of stimuli. This temporary condition is not a clinical illness or a personality disorder. ...

I used to work for a company well-known for its modification state-specific antibodies, including phospho-specific ones, and they actually performed extensive in-house testing of PBST vs. TBST in Western blotting. Part of the reason the company chose to recommend the use of Tris-buffered saline over phosphate-buffered saline based buffers was the clearly-...

If you are asking solely about data structure, the two data formats that you have given are essentially the same. Each row represents a PPI, so in a network a line (edge) will link the proteins (nodes) given in columns one and two. Column three is an edge score, but it can indicate a few things, confidence in the interaction or strength of the interaction. ...

Your limited understanding is indeed correct - the different colours indicate different stages of maturation, even though different colour cultivars exist (e.g. some that remain green even if fully ripe). It is known that the different maturation states have different vitamin and/or mineral concentrations (see here or here). This indicates that different ...

The missing science to the question is the failure to realize that water inside a cell is bound to hydrophilic proteins which form an exclusion zone. This EZ is well described in the literature by Pollack. The EZ carries a strong net negative charge and it excludes protons. This has also been confirmed by numerous researchers across the world. The ...

According to David H. Vroon and Zafar Israili aminotransferases (transaminases) are widely distributed among tissues, and are found in both cytoplasm and mitochondria, although this may vary between different aminotransferases: Aminotransferases catalyze the redistribution of nitrogen between amino acids and corresponding oxoacids participating in both ...

Bacteria and plants are able to synthesize all amino acids, as they are capable of nitrogen fixation. If animals eat plants, they get the essential amino acids needed for their proteins. Humans get the essential amino acids by eating these animals or directly by consuming plants. So yes, it is a never-ending cycle of passing.

It depends how you define an acid. For what it‘s worth, the chemical definition Google presents when I search is “a molecule or other species which can donate a proton or accept an electron pair in reactions”. On that basis the serine residue in the catalytic triad is acting as a weakly ionizing acid. Of course in aqueous solution a free serine hydroxyl ...

As @WYSIWYG said in comments, there is no effect of change in nitrogenous base on the third phosphate. Why? Simple, they are too far to directly influence each other's stability. See the diagram (of ATP) below from wikipedia: and of GTP from here: What one can clearly interpret from these diagrams is that there would be no effect on the energy released ...

First off, the difference between the types of inhibition: competitive inhibition: The inhibitor only binds to the substrate-free form of the enzyme. (Not necessarily at the active site!) uncompetitive inhibition: The inhibitor only binds to the substrate-bound form of the enzyme. noncompetitive inhibition: The inhibitor binds equally well to both the ...

To be more detailed it is the irreversibly of the reaction carried by Pyruvate dehydrogenase that makes the conversion of the fatty acid chains to glucose impossible. The fatty acids chains are converted to acetyl-CoA. Acetyl-CoA to be converted into pyruvate need an enzyme that can do the Pyruvate Dehydrogenase's inverse reaction (in humans there is no ...

The oxidative deamination takes place inside the mitochondria, because the glutamate dehydrogenase is localized in the mitochondria. About the transamination, I'm not sure if it occur inside the mitochondria or in the cytoplasm. The information about the oxidative damination and the enzyme could be found at this link: http://www.bioinfo.org.cn/book/...
