The synthesis and the enzymatic degradation of l-tyrosyl-l-lysyl-l-glutamyl-l-tyrosine.
The formation of angiotonin from the serum protein fraction art-globulin and renin (1, 2) as well as its inactivation by proteolytic enzymes suggests that this pressor substance contains peptide linkages. Preliminary studies and interpretations (3) of the action of crystalline proteolytic enzymes led to the conclusion that angiotonin contains groupings of which the simplest representation is af...
متن کاملConformational properties of N-acetyl-L-alanine N',N'-dimethylamide.
Ab initio/DFT analysis of the conformational properties of free Ac-Ala-NMe(2) (N-acetyl-L-alanine-N',N'-dimethylamide) in terms of the N-H.O, N-H.N, C-H.O hydrogen bonds and C(delta+) = O(delta-) dipole attractions was performed. The Ala residue combined with the C-terminal tertiary amide prefers an extended conformation and that characteristic of the (i + 1)th position of the betaVIb turn. The...
متن کاملl-Alanine hydrochloride monohydrate
Colorless crystals of l-alanine hydrochloride monohydrate, C(3)H(8)NO(2) (+)·Cl(-)·H(2)O, were obtained from a powder sample that had been left standing in a refrigerator for a few years. The structure displays several inter-molecular hydrogen bonds: the hydroxyl O atom is involved in a single hydrogen bond to the chloride anion, while the ammonium group forms one hydrogen bond to the chloride ...

In view of the lack o realism of an AWGN model for ambient noise arising in many practical channels in which multiuser detection techniques may be applied, natural questions arise concerning the applicability, robustness, and performance of multiuser detection techniques for non-Gaussian multiple-access channels. In this paper, we consider the multiple access mitigation problem in DS-CDMA chann...

In ancient t imes, wax seals impressed with signet r ings were aff ixed to documents as evidence of their authent ic i ty . A digi ta l counterpart is a message authent icat ion code f ixed f i rmly to each important document. We sketch an archite cture that accompl ishes this by using encapsulat ion of content with provenance metadata, cryptographic seal ing, and webs of t rust rooted in respe...
