Vitamin B12 in Cats: Nutrition, Metabolism, and Disease
Animals, 2023 Cobalamin is a water-soluble molecule that has an important role in cellular metabolism, especially in DNA synthesis, methylation, and mitochondrial metabolism. Cobalamin is bound by intrinsic factor (IF) and absorbed in the ileal tract.

Geometric-algebraic approach to aqueous solutions of diprotic acids and its buffer mixtures [PDF]
arXiv, 2023 A closed-form analytical expression for $\ce{[H3O+]}$ has been obtained for aqueous solutions of diprotic acids and its soluble salts. This formula allows to calculate the pH of aqueous solutions of diprotic acids, their buffer solutions, and the titrations of these two by a strong base, from the values of p$K_1$, p$K_2$, and the effective ...

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.Abstract Objectives To examine the effects of lipid‐based nutrient supplements (LNS) containing milk protein (MP) and/or whey permeate (WP) on markers of intestinal inflammation and enterocyte mass among stunted children. Furthermore, to explore whether gut status modifies effects of LNS on growth and micronutrient status.

Monitoring Methylmalonic Aciduria by NMR Urinomics
Molecules, 2020 The paper reports on monitoring methylmalonic aciduria (MMA)-specific and non-specific metabolites via NMR urinomics. Five patients have been monitored over periods of time; things involved were diet, medication and occasional episodes of failing to ...

Large presence of carbonic acid in CO$_2$-rich aqueous fluids under Earth's mantle conditions [PDF]
Journal of Physical Chemistry Letters 10, 5135-5141 (2019), 2019 The chemistry of carbon in aqueous fluids at extreme pressure and temperature conditions is of great importance to Earth's deep carbon cycle, which substantially affects the carbon budget at Earth's surface and global climate change. At ambient conditions, the concentration of carbonic acid in water is negligible, so aqueous carbonic acid was simply ...

A Technique for Measurement of Methylmalonic Acid in Cattle Urine
Journal of Dairy Science, 1977 Methylmalonic acid was measured in cattle urine by decarboxylating it to propionate with sulfuric acid and heat and quantifying the propionate so formed by gas-liquid chromatography. Crystalline methylmalonic acid added to cow urine was recovered quantitatively.

Metabolic phenotype of methylmalonic acidemia in mice and humans: the role of skeletal muscle
BMC Medical Genetics, 2007 Background Mutations in methylmalonyl-CoA mutase cause methylmalonic acidemia, a common organic aciduria. Current treatment regimens rely on dietary management and, in severely affected patients, liver or combined liver-kidney transplantation.

Carbon Doping of MgB2 by Toluene and Malic-Acid-in-Toluene [PDF]
, 2010 The decomposition of malic acid in the presence of Mg and B was studied using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) which revealed that malic acid reacted with Mg but not B. Also, the addition of toluene to dissolve malic acid followed by subsequent drying resulted in no reaction with Mg, indicating that the malic

A search for mid-IR bands of amino acids in the Perseus Molecular Cloud [PDF]
arXiv, 2021 Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth. They are present in carbonaceous chondrite meteorites and comets, but their origin is still unknown. Formation of amino acids in the interstellar medium is posible via specific gas-phase reactions in dark clouds, however sensitive ...

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Protein sequence design is a highly challenging task, aimed at discovering new proteins that are more functional and producible under laboratory conditions than their natural counterparts. Deep learning‐based approaches developed to address this problem have achieved significant success.
