What is not a correct expression for the weak acid {eq}\rm HA {/eq}? A) {eq}\rm pK_a = \log K_a {/eq}. B) {eq}\rm \displaystyle pK_a = pH - \log \left \{\left [A^-\right]/\left [HA\right ]\right \} ...
Suppose you have a 0.25 M acetic acid solution with 0.6 M sodium acetate as it?s conjugate base. If the Ka value for this reaction Is 1. 6 x 10-5, what is the pH of the system? What is the net ionic equation for the reaction between aqueous...

Metabolic pathways of these compounds and their mechanisms of action on different pathologies can lead to the discovery of new diagnostic techniques, drugs and the potential use as functional ingredients in food. This review discusses the potential mechanisms by which amino acid catabolism is involved ...
When the iodometric method is used to determine the content of vitamin C, the purpose of adding dilute acetic acid is ( ) A. improve indicator sensitivity B. slow down the oxidation of vitamin C by oxygen in the air C. neutralize the alkaline substances in the reagent D. pr...
Another explanation might be that sTNFR2 has a vital role in the normal activity of several cortical regions associated with emotional responses such as the anterior cingulate cortex, dorsolateral prefrontal cortex, and hippocampus, so its under-expression might contribute to MDD pathogenesis [214]. ...
Well-known bacterial endotoxin (i.e., lipopolysaccharide: LPS) is a component of the bacterial wall of gram-negative bacteria and acts as one of the pathogen-associated molecular patterns (PAMPs) for Toll-like receptor (TLR) 4. Translocated microbial products activate KCs in the liver through ...
Fungi are commensal organisms in the oral microbiome, and the over-presence of such microorganisms or the expression of virulence factors could cause pathological conditions. In addition to the genera Cryptococcus and Aspergillus, Candida albicans is a commensal yeast of the oral cavity that is also...
Specialized cells enable the phloem tissue to achieve this: sieve-tube elements (SE; non-lignified cellulosic transport tubes without nucleus, vacuoles, and ribosomes), companion cells (CC; supporting cells capable of gene expression and translation), and phloem parenchyma cells. CC and parenchyma ...
The logarithmic levels of the most distinctive gut bacteria showed a strong correlation with the concentrations of TGF-β and IL-6 [16]. Moreover, 95 human metabolic pathways exhibited unique expression patterns in the brain tissues of individuals with ASD, which corresponded to microbial pathways ...
