Effects of buffering agents on high-intensity exercise performance and capacity [PDF]

, 2012
High-intensity exercise results in hydrogen ion accumulation, which can have a deleterious effect on muscle function, and thus exercise tolerance. Buffering agents are commonly used to enhance exercise performance and capacity. Two such agents, β-alanine

Critical role of bicarbonate and bicarbonate transporters in cardiac function

World Journal of Biological Chemistry, 2014
Bicarbonate is one of the major anions in mammalian tissues and extracellular fluids. Along with accompanying H(+), HCO3 (-) is generated from CO2 and H2O, either spontaneously or via the catalytic activity of carbonic anhydrase. It serves as a component of the major buffer system, thereby playing a critical role in pH homeostasis. Bicarbonate can also

CO₂/HCO₃⁻ Accelerates Iron Reduction through Phenolic Compounds

mBio, 2020
Iron is a vital mineral for almost all living organisms and has a pivotal role in central metabolism. Despite its great abundance on earth, the accessibility for microorganisms is often limited, because poorly soluble ferric iron (Fe3+) is the ...

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Evaluation of a bicarbonate-based algal carbon capture system for mushroom farms with concomitant generation of value-added products [PDF]

, 2023
The rise in anthropogenic carbon dioxide emissions has led to a need for efficient andscalable carbon capture systems. Microalgae offer a promising approach to carbon capture from a variety of sources, including industrial gases and dissolved inorganic ...

Identification and Reduction of Bitter Taste Determinant Compounds in Chocolate Spread Formulated with Candlenut

Caraka Tani: Journal of Sustainable Agriculture
Candlenuts can be used as a substitute in producing chocolate spread due to their high-fat content. However, the limitation of using candlenut in the spread formulation is the existence of a bitter taste.

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Regulation of plasma aldosterone during hemodialysis [PDF]

, 1990
In order to clarify the influence of serum potassium, serum sodium and plasma angiotensin II concentrations on aldosterone release during hemodialysis (HD), six chronic hemodialysis patients were studied during HD with varying dialysate sodium ...

tlpA gene expression is required for arginine and bicarbonate chemotaxis in Helicobacter pylori

Biological Research, 2011
About half of the human population is infected with Helicobacter pylori, a bacterium causing gastritis, peptic ulcer and progression to gastric cancer. Chemotaxis and flagellar motility are required for colonization and persistence of H.

Calcium-sensor proteins but not bicarbonate ion activate retinal photoreceptor membrane guanylyl cyclase in photoreceptors

Frontiers in Molecular Neuroscience
Retinal membrane guanylyl cyclase (RetGC), regulated by guanylyl cyclase activating proteins (GCAPs) via negative calcium-feedback, is one of the most critically important enzymes in vertebrate rod and cone physiology, enabling their sensitivity to light.
