    LysB28ProB29-human insulin (Humalog), a fully potent insulin analog in which the prolyl, lysyl sequence at the C-terminal end of the B-chain is inverted, exhibits a decreased association of monomers to dimers leading to rapid in vivo absorption. This provides important benefits for the insulin-requiring diabetic. In spite of its monomeric nature, LysB28ProB29-human insulin can exist as a discrete hexameric structure in the presence of both zinc and phenol. Studies of the crystal structure of LysB28ProB29-human insulin in a hexameric complex were initiated to gain a molecular understanding of the effect of the sequence inversion on the analog's self-association properties and, consequently, its in vivo efficacy.
