A one-pot synthesis procedure is designed for preparing three 伪-aminophosphonates (R-H, R-COOH, and R-NH2); through the reaction of amine precursors (aniline, anthranilic or o-phenylene diamine, respectively) with salicylaldehyde and triphenylphosphite, under controlled conditions. These materials...
mainly DNA methylation (Fig.4). DNA methylation is catalyzed by DNA methyltransferases, which transfer methyl group from SAM to DNA. As a methionine transporter, SLC7A5 is crucial for intracellular methionine concentration. Disruption in methionine concentration is closely associated...
Amino acidsare fundamental molecules of life.Amino acidscontain an amine group, acarboxylic acidgroup, and a side chain (R) that varies between differentamino acids. Amino acids contain the key elements of carbon, hydrogen, oxygen, and nitrogen. In an alphaamino acid, the amino group is attac...
product putreamine in allergen-stimulated lungs.221The addition of L-citrulline (a precursor of the L-arginine cycle and NO synthesis) to medications in obese asthmatic patients may assist in asthma control and improve fractional NO excretion (FeNO) levels.222 In chronic obstructive pulmonary diseas...
DPss with multiple amine groups, like His-containing DPs, generally showed lower signal intensities compared to those with a single amine group. Statistical analysis Results in figures are presented as mean ± SD unless stated otherwise. Correlations were calculated using Spearman correlation ...
In the reactions that convert DDA to ω-AmDDA, NADPH is essential for DDA hydroxylation catalyzed by CYP153A-NCP, while NADH is required by AlaDH2 catalyzing regeneration of L-alanine which is used as the amine donor in the transamination reaction6. In the de novo biosynthesis of ω-AmDDA...
It can also be used as a solvent as well as a template to synthesize layered aluminophosphate containing a racemic mixture of isopropanolamine. Definition ChEBI: Any amino alcohol that is propan-2-ol substituted by an amino group at position 1. ...

Carnitine is a quaternary amine required for the transport of long-chain fatty acids into the mitochondria, where they undergo oxidation.26Premature infants are at risk for carnitine deficiency because of their limited carnitine reserves and reduced carnitine synthesis.181Decreased fatty acid oxidation an...
When the azide group was preconjugated with DBCO-amine, the rate constant was 39,045 M−1 s−1, which is on the same order of magnitude as the rate constant for the sfGFP-Y151-pTAF tetrazine reaction for the unreacted azide (Supplementary Figs. 9 and 10). To further rule out ...
