But a beta-pleated sheet has polypeptide chains connected "head" (carboxyl) to tail in alternating directions according to the definition of Secondary Structure in my textbook. That being the case, the head-to-tail binding can only be hydrogen bonding - much like the pairs of strands (molecules) of DNA in a helix. And if molecules only contain covalent or ionic bonds, then the beta-pleated ... Description. Fragment 176-191 for sale is available in lyophilized powder form, in 5mg vials.. About Fragment 176-191: GH Fragment is a modified form of amino acids 176-191 of the human Growth Hormone (GH) polypeptide.This peptide, as the name implies, is a piece of the 191 amino chain that makes up growth hormone, from positions 176 through 191 to be exact. This mechanism of polypeptide binding is in fact reminiscent of how many chaperones, such as Hsp70s, interact with a broad range of peptide substrates ; in these cases, extended polypeptide chains are embraced by the walls of a deep groove, making side chain interactions less important. I understand the charge placement on the N & C-terminus and also the utilization of the R-side groups in the amino acids. For example, What is the overall charge for a chain Glu-Cys-Arg-Asp with pH 11.0 buffer? biochemistry proteins ph. share improve this question follow asked Dec 3 '15 at 20:46. alfa_jo alfa_jo. 94 1 1 silver badge 5 5 bronze badges $\endgroup$ add a comment 1 Answer ... A chain of more than 50 amino acids is called a protein. Chains of amino acids in general can be called polypeptides - which refers to the type of bond between the amino acids (a peptide bond).
