They are usually artificial peptides or proteins with amolar massof about 3 to 20 kDa. 通常它是人造的肽或者蛋白质,摩尔质量介于3至20kDa之间。 LASER-wikipedia2 Victor Meyer apparatus: In a demonstration in Cohen's Practical Organic Chemistry (1910) themolar massof diethyl ether was determined ...
With one molar equivalent of anhydrous HCl, the simple addition product 6a can be formed at low temperature in the presence of ether, but it is very unstable. Jedním molárním ekvivalentem chlorovodíku lze při nízké teplotě a za přítomnosti diethyletheru vytvořit jednoduchý...
