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.

Organ‐on‐Chip: The Future of Nutrition Research in a One Health World

Food Frontiers, EarlyView.
Organ‐on‐chips offer a promising tool for evaluating food and feed safety. Organ‐on‐chips also present a scientifically robust and ethical alternative to animal studies. ABSTRACT The One Health approach emphasizes the interconnectedness of human, animal, and environmental health, recognizing that the health of each is interdependent and influenced by ...

Metabolism of n-3 polyunsaturated fatty acids and modification of phospholipids in cultured rabbit aortic smooth muscle cells.

Journal of Lipid Research, 1985
The metabolism of the linolenic acid family (n-3) of fatty acids, e.g., linolenic, eicosapentaenoic, and docosahexaenoic acids, in cultured smooth muscle cells from rabbit aorta was compared to the metabolism of linoleic and arachidonic acids.

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

Microalgae: A Solution for Food Security and Multiplanetary Farming

Food Frontiers, EarlyView.
ABSTRACT Human civilization is threatened by food insecurity and habitat loss owing to the cumulative effects of anthropogenic and natural factors. Thus, increasing food production while using fewer resources and exploring the potential of interstellar migration is essential.

Highly Targeted Metabolomics Coupled With Gene Expression Analysis by RT–qPCR Improves Beef Separation Based on Grass, Grain, or Grape Supplemented Diet

Food Frontiers, EarlyView.
ABSTRACT The objective of this study was to use a multi‐omics (i.e., gene expression quantification, metabolomics, and fatty acid [FA] profiling) approach to separate and authenticate beef from three different dietary groups. In this 2‐year study, Red Angus steers (n = 54) were randomly allocated to one of three treatments: (1) complex biodiverse ...

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).

Modification of spleen phospholipid fatty acid composition by dietary fish oil and by n-3 fatty acid ethyl esters

Journal of Lipid Research, 1993
We have compared the effects of diets containing purified ethyl esters of either eicosapentaenoic acid, docosahexaenoic acid, or a mixture of both of these compounds, with diets containing either purified fish oil or beef tallow on spleen phospholipid ...

Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

FABP7 Expression Modulates the Response of Astrocytes to Induced Endotoxemia

Glia, EarlyView.
FABP7 silencing reduces inflammatory response in astrocytes. FABP7 silencing decreases astrocyte‐mediated neurotoxicity. FABP7 silencing attenuates NF‐κB‐dependent transcriptional response during endotoxemia. ABSTRACT Fatty acid binding proteins (FABPs) are a family of small proteins involved in fatty acid (FA) subcellular trafficking.
