Chemically Fuelled Deracemization of Amino Acids [PDF]
openSystems that work out-of-equilibrium are common in nature, living organisms are the most striking example of that. Chemists are trying to mimic living organisms because of the multitude of properties that might be implemented in synthetic systems ...

Amino Acids, Amino Acid Derivatives and Peptides as Antioxidants
[Excerpt] The biological concept of antioxidant refers to any compound that is able to delay or 5 prevent the oxidation of easily oxidizable substrates, such as DNA, proteins and 6 lipids. Antioxidants reduce oxidative stress and mutations in DNA as well as other 7 parameters associated with cell damage.

Role of amino acid transporters in amino acid sensing [PDF]
Amino acid (AA) transporters may act as sensors, as well as carriers, of tissue nutrient supplies. This review considers recent advances in our understanding of the AA-sensing functions of AA transporters in both epithelial and nonepithelial cells.

IntroductionL-Glutamate is a conditionally essential amino acid, meaning it can become essential under specific conditions, like stress or disease. It is an abundant intracellular amino acid crucial in immune responses.

Physiology of the Amino Acids [PDF]
We have followed the amino acids from their entrance into the alimentary tract in the form of food proteins through the successive steps of digestion, absorption into the blood stream and passage from the blood stream into the tissues, where they are concentrated by some unknown mechanism to many times their concentration in the blood plasma.

Amino acid neurotransmitters in the CNS
D‐Aspartate exchange, defined as amino acid‐stimulated D‐[3H]aspartate efflux, was investigated in a preparation of rat brain synaptosomes. The efflux of radiolabelled D‐aspartate was found to be enhanced by micromolar concentrations of externally added D‐ and L‐aspartate, L‐glutamate, L‐cysteate.and L‐cysteinesulphinate.

We analyzed the structure of horseradish peroxidase (HRP) under denaturing conditions of 9 M urea or 6 M guanidine hydrochloride (GdnHCl). Far-UV circular dichroism (CD) spectra indicated the existence of native-like secondary structure of holo-HRP in 9 ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
