All amide bonds in the general formula I, except for the bond between C and D can be substituted independently on each other with the group -Y-NRe18-, in which Y represents the group -CO- or -CHi2- and Re18 represents a hydrogen atom, alkyl containing 1 to 6 carbon atoms or aryl...
Small oligomers formed early along human islet amyloid polypeptide (hIAPP) aggregation is responsible for the cell death in Type II diabetes. The epigallocatechin gallate (EGCG), a green tea extract, was found to inhibit hIAPP fibrillation. However, the
单么步也身近张其全两世低反Which of the following molecules utilize a peptide bond to form a dipept
Upon binding to Nt-Arg and synthetic ligands to its ZZ domain, p62 undergoes disulfide bond-linked self-aggregation and interacts with LC3 on autophagic membranes, leading to the co-delivery of p62 and its cargoes to the autophagosome. In addition, ligand-bound p62 induces autophagosome biogenesis...
The invention relates to a process for the preparation of an insulin derivative of the formula I ##STR1## in which R1denotes H or H-Phe, R30represents the radical of a naturally occurring L-aminoacid and R31represents a physiologically acceptable organic group of neutral or basic character co...

Thus, for example, pepsin digests an antibody below the disulfide linkages in the hinge region to produce F(ab)′2, a dimer of Fab which itself is a light chain joined to VH-CH1 by a disulfide bond. The F(ab)′2 may be reduced under mild conditions to break the disulfide linkage ...
