Applications · 1 item

UsesSynthesis of hyperbranched polylysine using the N-hydroxysuccinimide ester of L-lysine dihydrochloride as AB 2 building block. The histidine and lysine standards were prepared from L-histidine monohydro- chloride and L-lysine dihydrochloride respectively. L-Homocitrulline-The copper complex was prepared from L-lysine dihydrochloride in 80 to 86 per cent yields.
