Typical structural characteristics and hepatoprotective effects of novel high Fischer ratio oligopeptides from Antarctic krill on acute alcoholic liver injury.

High Fischer ratio oligopeptides derived from Antarctic krill (HFOPs-AK) were screened, and their hepatoprotective effects and potential mechanisms were investigated. Herein, HFOPs-AK, with a Fischer ratio of 29 g/g (40.22 mol/mol) (MW < 1000 Da), were prepared two-step enzymatic hydrolysis using chymotrypsin and flavourzyme and aromatic amino acid removal.

Enhancing mucoadhesion: Exploring rheological parameters and texture profile in starch solutions, with emphasis on micro-nanofiber influence.

This comprehensive analysis explores the rheological parameters and texture profile analysis (TPA) to effect starch solutions for mucoadhesion and assess the impact of micro-nanofibers (MNFs) on these parameters. The surface chemistry of all six samples was examined through the Fourier transform infrared (FTIR) technique. The spectrum of FTIR was recorded in the range of 500-4000 cm.

Identification of Hyperuricemia Alleviating Peptides from Yellow Tuna .

The development of food-derived antihyperuricemic substances is important for alleviating hyperuricemia (HUA) and associated inflammation. Here, novel peptides from (TAP) with strong antihyperuricemic activity were prepared. TAP was prepared by alkaline protease (molecular weight <1000 Da), with an IC value of xanthine oxidase inhibitory activity of 2.

Isolation and differential structure characteristics of calcium-binding peptides derived from Pacific cod bones by hydroxyapatite affinity.

Calcium-chelating peptides were found in Pacific cod bone, but their binding structure and properties have not been elucidated. Novel calcium-binding peptides were isolated by hydroxyapatite affinity chromatography (HAC), and their binding structure and properties were investigated by isothermal titration calorimetry (ITC), multispectral techniques, and mass spectrometry. Based on multiple purifications, the calcium binding capacity (CBC) of Pacific cod bone peptides (PBPs) was increased from 1.

Contribution of secondary bonds to the storage stability of ready-to-eat sea cucumber.

To explore the contribution of secondary bonds on storage stability of RSC, urea, n-propanol and sodium nitrite (NaNO) were used for the breakdown of hydrogen bonds, hydrophobic bonds, side-chain groups, respectively. The impact of the breakdown of secondary bonds before and after storage on texture properties and microstructure were investigated. The breakdown of hydrogen bonds, especially before storage, significantly reduced the hardness (from 3.

A comprehensive review of calcium and ferrous ions chelating peptides: Preparation, structure and transport pathways.

Calcium and iron play crucial roles in human health, deficiencies of which have globally generated public health risks. The poor solubility, low bioavailability and gastrointestinal irritation of existing commercial mineral supplements limit their further application. As an emerging type of mineral supplement, mineral chelating peptides have drawn plenty of attention due to their advantages in stability, absorptivity and safety.
