Product Application

Itha kugwiritsidwa ntchito ngati shrinkage wothandizira, chothandizira ndi wothandizira wothandizira. Mu kaphatikizidwe ka peptide, kuwonjezera kwa othandizira a condensation kumatha kufulumizitsa zomwe zimachitika komanso kuchepetsa kuthamanga kwamtundu, kuti apange kuchepa kwa ma condensation reagents. HOPO ndi mitundu yosiyanasiyana yothandizira condensation. 2-hydroxypyridine-n-oxide ndi chinthu chofunikira kwambiri. Kafukufuku waposachedwapa apeza kuti pawiriyi ili ndi gawo lapadera poletsa kuwonongeka kwa nkhuni chifukwa cha white-rotfungi. Nthawi yomweyo, ndi njira yatsopano komanso yothandiza ya subway chelating. Zovuta zomwe zimapangidwa ndi pawiri ndi vanadium zimathandizanso kwambiri pazachilengedwe.
