A team of chemists at the University of Cambridge has developed a metal-free way to convert symmetrical diols selectively ...

储存条件：NH2-PEG-Retinol应在-20℃下长期保存，并保持避光和干燥的环境。避免高温、潮湿和光照以防止化合物降解或失去活性。 取用注意事项：取用前应将产品放置至室温以避免因温度差异导致的吸潮或结晶。取用时应注意防止污染并确保使用干净的器具。

The amine-reactive Alexa Fluor 568 carboxylic acid, succinimidyl ester, and its conjugates are excited by the 568-nm line of the Ar-Kr laser and yield bright, orange-red fluorescence, brighter ...

Diagram showing the functionalization of a metal oxide nanoparticle with various organic molecules, including trimethoxysilane, amine, phosphonic acid, carboxylic acid ... are attached to the surface ...

It seems probable that threose is a major factor in Maillard reactions involving ascorbic acid. In very acid media, e.g., lemon juice (pH 2.5), sugar amine reactions are unlikely and browning occurs ...

(2001) Sugar model of the origin of life: Catalysis by amines and amino acid products ... of Peptide Thioesters from Amino Acids and a Thiol Using 1, 1'-Carbonyldiimidazole, Orig. Life Evol.

Semiconductors have a valence band that is filled with electrons and an empty conduction band separated by a band gap (also called energy gap). For an electron to be excited into the conduction ...

A nearly limitless variety of molecules can be attached to the surface of AuNPs, commonly using thiol, amine, disulfide, carboxylate and phosphine ligands to form linkages with AuNP surfaces.

Both disappointed at not having won but satisfied at having held on for a draw despite being a man down against Lille (0-0), the midfielder and the attacker spoke afterwards in the mixed zone. They ...
