Prevalent intrinsic emission from nonaromatic amino acids and poly(amino acids)

Polyamino acids take amyloid form

Viva the worm ike yin and yang, good things usually come at a cost. If you live longer, then you give up reproductive fitness in return. The merits of this model—termed antagonistic pleiotropy—have been argued by evolutionary biologists for half a century. Some believe that the effort of reproduction is necessarily linked to deterioration characteristic of aging. have challenged the idea by unc...

Hydrogen-addition radicals formed in the aromatic rings of amino acids, polyamino acids, and proteins.

Since the original detection of electron spin resonance (ESR) signals from free radicals formed by ionizing irradiation in the amino acids and proteins,' numerous ESR studies of these and other powdered peptides have been made.2-'0 The free radicals that have been identified in these studies have been formed for the most part by the breakage of a CaH bond to leave the electron spin concenltrate...

Electrochemical Analysis of Polyamino Acids and Proteins

Synthesis and Biomedical Applications of Polyamino Acids

Polyamino acids are able to adopt ordered conformations, such as α-helices and β-sheets, through cooperative hydrogen bonding. These conformations impart polyamino acids with various unique properties and functions in biological environments. The development of controlled ring-opening polymerization (ROP) of α-amino acid N-carboxyanhydrides (NCAs) in the past two decades has enabled the synthes...

conjugated linoleic acids, amino acid profile and other characteristics of meat produced under identical condition from two iranian fat tailed breeds of lamb

گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
