In this work the chirality and the relative thermal stability of ordered micellar aggregates of poly-L- and poly-D-glutamic acids with the cationic surfactant C14TAB is examined. The complexed mesophases poly-L-Glu/C14TAB and poly-d-Glu/C14TAB were characterized by circular dichroism (CD) in the

The thermal stability of the self-assembled complexes formed by alkyltrimethylammonium surfactants and poly(alpha,l-glutamate) is investigated in dilute chloroform solution by molecular dynamics simulations. By applying temperatures ranging from 300 to 500 K, we observed an extraordinary stability of the alpha-helix

Erythropoietin (EPO), a 34-kDa glycoprotein, is produced predominantly by peritubular interstitial cells (PIC) in the renal cortex and is physiologically released when ambient oxygen pressure falls. However, the exact nature of EPO-producing cells in the kidney is not well understood.

Amyloid fibrils, which are often associated with certain degenerative disorders, reveal a number of intriguing spectral properties. However, the relationship between the structure of fibrils and their optical traits remains poorly understood. Poly(L-glutamic) acid is a model polypeptide shown recently
