Biogenic Next‐Gen CPL Emitters: Strategies with Proteins, Polysaccharides, and Nucleotides

Advanced Optical Materials, EarlyView.
Biogenic molecules such as proteins, peptides, saccharides, and DNA can act as natural scaffolds for generating circularly polarized luminescence (CPL). This review highlights recent strategies exploiting these inherently chiral frameworks to achieve light emission with controllable handedness under unpolarized excitation, bridging biological ...

Free amino acids in a cave beetle \u3cem\u3eDarlingtonea kentuckensis\u3c/em\u3e Valentine (Coleoptera: Carabidae) [PDF]

, 1974
Free amino acids of Darlingtonea kentuckensis were investigated by two-dimensional, thin-layer chromatography on Silica Gel G. Thirteen amino acids which could be identifìed (alanine, glutamic acid, glycine, histidine, isoleucine and/or leucine, lysine ...

Synthetic Vasopressin and Oxytocin Analogs and Their Potential Use in Hemorrhagic, Traumatic and Septic Shock: A Personal Perspective [PDF]

, 2017
As one of us has stated many years ago, “shock is a significant and sustained loss of effective circulating blood volume. It will eventuate in hypoperfusion of critical peripheral tissues, thus leading to a deficit in transcapillary exchange function in ...

Identification of a plastidial phenylalanine exporter that influences flux distribution through the phenylalanine biosynthetic network

Nature Communications, 2015
In addition to proteins, L-phenylalanine is a versatile precursor for thousands of plant metabolites. Production of phenylalanine-derived compounds is a complex multi-compartmental process using phenylalanine synthesized predominantly in plastids as ...

Conversion of D-phenylalanine to L-phenylalanine in humans.

Nippon Eiyo Shokuryo Gakkaishi, 1988
健康な女子2名にD-Phe-d5を8mg/kg体重, 他の必須アミノ酸および低タンパク質食とともに経口負荷し, 1, 4, 8時間後に採血した。血漿中の遊離フェニルアラニンをHPLCによりDL分割し, L画分について, Phe-d5/Phe-d0モル比をGC-MS-MIDにより測定した。この結果から, 血漿中のD-Phe-d5および, これから変換したL-Phe-d5の量を, 血漿中に天然に存在しているL-Phe-d0とのモル比として算出した。負荷後の血漿中のD-Phe-d5/L-Phe-d0モル比の最低は負荷1時間後の0.38 (被験者S: 0.16, T: 0.60の平均値), 最高は負荷4時間後の0.78 (S: 0.72, T: 0.84) であった。-Phe-d5/L-Phe ...

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Synthesis of d- and l-Phenylalanine Derivatives by Phenylalanine Ammonia Lyases: A Multienzymatic Cascade Process**

Angewandte Chemie, 2015
The synthesis of substituted d-phenylalanines in high yield and excellent optical purity, starting from inexpensive cinnamic acids, has been achieved with a novel one-pot approach by coupling phenylalanine ammonia lyase (PAL) amination with a ...

CO2 Capture, Utilization, and Storage using Amino Acids

Advanced Sustainable Systems, EarlyView.
Amino acid and amino acid‐based ionic liquids show potential for sustainable CO2 capture, benefiting from reactive NH2 groups and low‐energy regeneration. Their use in solvents, functionalized sorbents, direct air capture, mineralization, and CO2 conversion highlights their versatilty and promise for advacing next‐generation CO2 sequestration ...

Pre‐Administration of Akkermansia Muciniphila Prevents the Development of Severe Acute Graft‐Versus‐Host Disease in Systemic Organs

Advanced Science, EarlyView.
Akkermansia muciniphila, a next‐generation probiotic, alleviates acute graft‐versus‐host disease (aGvHD) following allogeneic hematopoietic stem cell transplantation (HSCT) by providing protective effects across multiple organs. Pre‐colonization with A.
