“…It was found that hybrid catfish skin collagen hydrolysate prepared by pepsin showed the higher ACE inhibitory activity when compared to the activity found in tilapia skin hydrolysates. Additionally, after cation exchange and two steps of size exclusion chromatography, hybrid catfish skin peptides showed ACE inhibitory activity of 72 % [124].…”

Skin Surface Chemistry as a Diagnostic Tool for Skin Diseases

The skin is the biggest sense organ in the body, with a surface area of 1.7m2 in adults. Because standard histological procedures influence skin components, several dermatological research has had little effectiveness in showing skin function. The structure of each skin layer may now be visualised non-invasively thanks to recent advances in non-invasive optical imaging. Individual skin components, on the other hand, remain difficult to identify. Understanding skin's chemical and physical features helps the cosmetics sector create deodorant, lipstick, and moisturizers. In addition, PH regulates the activation of proteases linked to the formation of chronic wounds and impacts skin barrier functions. Optical coherence tomography (OCT) is a non-invasive optical imaging innovation that creates high-resolution photos of the face and cross-areas of the skin. While OCT has a lot of potentials, many dermatologists are unfamiliar with it. This article aims to give professional dermatologists a basic grasp of skin OCT concepts and clinical applications.

“…Recent studies have indicated that the chelates formed by peptides and zinc can enhance stability, zinc absorption, and bioavailability (Zhu et al, 2013;Wang et al, 2014). Collagen peptides are hydrolysed from collagen, contributing to the unique physiological functions of tissues in skins, tendons, bones, and cartilages (Ab-Aziz et al, 2020;Salvatore et al, 2020;Sungperm et al, 2020). When compared with collagen, collagen peptides are more easily absorbed by humans because of their lower molecular weight (Fan et al, 2016).…”

Collagen peptide chelated zinc (CPCZ) nanoparticles were prepared using collagen peptide hydrolysate from tilapia scales. The nano-chelating ability of collagen peptide hydrolysates treated with ten enzymes was evaluated. Among these collagen peptide hydrolysates, trypsin hydrolysate exhibited the best nano-chelating ability. The molecular weight distribution of trypsin hydrolysate that produced CPCZ nanoparticles indicated that most of the peptides were less than 1,000 Da. These small molecular peptides with excellent nanozinc-chelating ability were chelated with zinc ions to form CPCZ nanoparticles. CPCZ nanoparticles were nearly spherical with an average diameter of approximately 100 nm, and a zinc content of 13.2%. Transmission electron microscopy coupled with energy dispersive spectroscopy and Fourier transform infrared spectrometry was used to measure the physicochemical properties of the CPCZ nanoparticles. Their cytotoxicity was also estimated by BHK21 cells. Result indicated that the CPCZ nanoparticles were non-toxic to BHK-21, and such nanoparticles significantly enhanced the survival of cells. The present work suggested that CPCZ nanoparticles could be used as zinc supplementation in the food and pharmaceutical industries.
