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 ...

Acid zeta function and ajoint acid zeta function [PDF]
arXiv, 2010 In this paper we set up the theory of acid zeta function and ajoint acid zeta function, based on the theory, we point out a reason to doubt the truth of the Riemann hypothesis and also as a consequence, we give out some new RH equivalences.

Uric Acid and Plant-Based Nutrition
Nutrients, 2019 Plant-based diets (PBDs) are associated with decreased risk of morbidity and mortality associated with important noncommunicable chronic diseases. Similar to animal-based food sources (e.g., meat, fish, and animal visceral organs), some plant-based food ...

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]
arXiv, 1999 Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

Effects of Uric Acid on Diabetes Mellitus and Its Chronic Complications
International Journal of Endocrinology, 2019 With the deepening of the researches on uric acid, especially in the study of metabolic diseases, uric acid has been found to be closely related to obesity, metabolic syndrome, nonalcoholic fatty liver disease, diabetes, and other metabolic diseases ...

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]
arXiv, 2006 The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

Journal of Biological Chemistry, 2019 Dietary, fructose-containing sugars have been strongly associated with the development of nonalcoholic fatty liver disease (NAFLD). Recent studies suggest that fructose also can be produced via the polyol pathway in the liver, where it may induce hepatic

The Factors of the Classification of Protein Amino Acids [PDF]
This paper is published in GLASNIK of Montenegrin Academy of
Science and arts, 2000, 13, pp. 173-194, 2006 In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).
