Hoʻohana Huahana

Hiki ke hoʻohana ʻia e like me ka shrinkage agent, catalyst a me ka mea kōkua. I ka peptide synthesis, hiki i ka hoʻohui ʻana o nā mea kōkua condensation ke wikiwiki i ka wikiwiki o ka hopena a hoʻemi i ka racemization, i mea e hoʻopau ai i ka nele o nā condensation reagents. ʻO HOPO kekahi ʻano o ia mau mea kōkua condensation. He mea nui ka 2-hydroxypyridine-n-oxide. Ua ʻike ʻia nā haʻawina hou he kuleana koʻikoʻi kēia hui i ka pale ʻana i ka hōʻino ʻana o ka lāʻau ma muli o ke keʻokeʻo-rotfungi. I ka manawa like, he mea hou a maikaʻi ka subway chelating agent. ʻO ka paʻakikī i hoʻokumu ʻia e ka pūhui a me ka vanadium he mea nui hoʻi i ka biochemistry.
