β-peptides are peptide-mimetics with wide biomedical and biotechnological applications. Their most peculiar feature is their readiness to fold into various secondary structures not found in natural counterparts. Furthermore, β-amino acid insertions polypeptides were provide unique features also increase enzymatic stability. This due the additional methylene group backbone, which on other hand m...

Proteins and peptides, built from precisely defined amino acid sequences, are an important class of biomolecules that play a vital role in most biological functions. Preparation nanostructures through functionalization natural, hydrophilic proteins/peptides with synthetic polymers or upon self-assembly all-synthetic amphiphilic copolypept(o)ides acid-containing enables access to novel protein-m...

Abstract Milk from different species has been exploited for the isolation of various functional ingredients decades. Irrespective source, milk is considered as a complete food, it provides essential nutrients required by human body. Proteins and their fractions are valuable sources bioactive peptides that might exert health beneficial role in body such immune-modulation, antioxidant activity, A...

Introduction: Venoms are a mixture of proteins and peptides which can be used for fighting cancers. They can affect the exposed fibers and the muscles directly or through motor nerves, causing neuromuscular intoxication. ICD-85 is a combination of three poly-peptides derived from the venoms of an Iranian brown snake and a yellow scorpion. Materials and Methods...

lactoferrin (lf) is an iron-binding multi-functional glycoprotein which has numerous physiological functions such as iron transportation, anti-microbial activity and immune response. in this study, different in silico approaches were exploited to investigate lf protein properties in a number of mammalian species. results showed that the iron-binding site, dna and rna-binding sites, signal pepti...

Iron–sulfur clusters are ubiquitous cofactors that mediate central biological processes. However, despite their long history, these metallocofactors remain challenging to investigate when coordinated small (≤ six amino acids) oligopeptides in aqueous solution. In addition being often unstable vitro, iron–sulfur can be found a wide variety of forms with varied characteristics, which makes it dif...

Insects or products derived from insects are considered as a valuable feed ingredient for aquaculture, poultry, and pigs but also exert possible secondary effects of health stimulators in livestock reported literature. Health benefits attributed to can create additional value the insect chain. Three categories bioactive compounds this desk study: antimicrobial peptides (such ?-helical peptides,...
