and Laminaria hyperborea have antimicrobial activity.113 In addition, polysaccharides extracted from Sargassum swartzii effectively inhibit the growth of both Gram-positive and Gram-negative bacteria.114 A fatty acid is a carboxylic acid consisting of a hydrocarbon chain and a terminal carboxyl group. ...
A truncated gene 2.5 protein (GP2.5-delta 21C) was constructed by in vitro mutagenesis and lacks the 21 carboxyl-terminal amino acids found in wild-type gene 2.5 protein, 15 of which are acidic. GP2.5-delta 21C cannot substitute for wild-type gene 2.5 protein in vivo; the phage are not...
PURPOSE:To provide the title composition having high surface-active ability even under weakly acidic conditions, containing specific amino acid-type surfactant(s) containing plural carboxyl groups. CONSTITUTION:The objective composition containing at least one amino acid- type surfactant having in one ...
Intracellular hydrolysis of the ester is followed by a putative nucleophilic attack on the phosphorus by the negatively charged carboxyl group, resulting in the spontaneous elimination of phenol, producing a highly unstable five-membered ring. A nucleophilic attack from a water molecule opens up this ...
Amino acids are molecules made up of an amino group, an acidic carboxyl group, and an organic R group. They are coded for with various combinations of three DNA nucleotides. Humans have 20 different amino acids that are used to produce all the proteins the body needs. Biologists suggest ther...
[GFP]) were either fused to the amino or carboxyl terminus of p7A, p7, p8, RPP3A, eIF3g1, and WRKY36 cDNAs. Next, recombinant cDNAs were inserted between CaMV 35 S promoter and PoPit terminator into pMOG80069by using the oligonucleotides and restriction enzymes listed in Supplementary...
Diphenic Acidhas a central phenyl core, and two of them are connected through a single carbon-carbon key. Each benzene ring is connected to a carboxyl group (COOH) in the opposite position. This structure gives Diphenic Acid two carboxylic acid groups, making it a di carboxylic acid. ...
Amino acids usually generate polymers in a condensation reaction when a specific amino group reacts with another amino group containing a carboxyl group. More often, the carboxyl group related to the amino acid has to be activated prior the better provision of a leaving group than the hydroxyl ...
(Fig.3dand Supplementary Fig.8e). In addition, the C1-carboxyl group of product maintains similar hydrogen-bonding interactions with the sidechain of Arg347 as that of D-lactate; however, the C2-keto group makes no hydrogen-bonding interaction with the sidechain of Glu442 (Fig.3dand ...
Acetic acidhas an acidic character because the hydrogen center in the carboxyl group (-COOH) separates via ionization to release a proton: CH3CO2H → CH3CO2−+ H+ This makes acetic acid a monoprotic acid with a pKa value of 4.76 in aqueous solution. The concentration of the solution gr...
