A novel antioxidant peptide was isolated from skipjack tuna bone collagen.
Abstract Pyrolysis is one of the most common, sustainable, and excellent environmental‐friendly method to evaluate bio‐energy potential different types biomass wastes. Pomegranate peel a well‐known low‐cost industrial waste. Thus, pomegranate peel's physicochemical properties were explored in detail, pyrolysis kinetic study thermal behavior analysis performed. Thermal degradation was investigated on heating rates (5, 10, 15, 20°C/min) by using TG‐DSC. To calculate parameters ( E , A ), three...
Exaggerated global efforts to endorse a circular economy for resolving environmental concerns along with high energy demand have enhanced interest the valorization of waste biomass. This study investigates sustainable utilization biomass through pyrolysis kinetics jujube pits. Jujube pits are abundant agricultural byproducts potential generation and value-added material production. Pyrolysis elucidate thermodynamic kinetic parameters governing decomposition process, crucial optimizing...
Ethyl carbamate (EC) has been associated with the generation of reactive oxygen species (ROS) and depletion glutathione (GSH), leading to a decline in cell viability. In this study, we found that cuttlefish collagen hydrolysate (CCH) exhibited high antioxidant activity scavenging hydroxyl radicals (IC50 = 0.697 mg mL-1), which was also effective combating EC-induced oxidative damage liver hepatocellular carcinoma HepG2 cells. The expression genes related stress response could be regulated by...
Transgenic plants may prove to be one of the most economical systems for large-scale production proteins and peptides. Our goal is develop an approach protein recovery from canola that will adaptable a wide variety recombinant proteins. For recovery, two downstream processes considered were extraction target purification host other impurities. In these experiments, T4 lysozyme has been added extracts as example simulate while evaluating merits several candidate precipitation strategies...
Abstract Compared to fossil fuels, renewable fuels (biodiesel) are promising alternatives with similar properties which could reduce the emission of toxic gases and carbon foot print. Biodiesel is mostly used in some developing countries especially transportation sector can be produced from vegetable oils, animal fats, non‐edible oil, waste cooking oil by different methods. Animal fat not feasible for biodiesel production because numerous problems during production. Catalysts selected or...
Bradykinin-potentiating peptides (BPPs) are snake venom inhibiting the angiotensin-converting enzyme (ACE). ACE plays an important role in regulation of blood pressure. BPPs lead to development inhibitors for treatment hypertension.The objective present work was carry out a comprehensive comparative study four synthesised vivo.Four were administered rats via intraperitoneal route 15 days at fixed dose. Lisinopril used as standard. Thirty male albino divided into six groups: A, B, C, D, E...

Preparation biologically important bearing peptides has been demonstrated reduction ”‐aminomethyl)methano‐3,4‐dideoxy‐α‐...
Synthesis of Disubstituted Cyclopropa[ c ]pyranosides from 2,3‐Epoxy‐4‐triflate‐pyranosides Reaction benzyl 2,3‐anhydro‐4‐ O ‐trifluoromethylsulfonyl‐β‐ L ‐ribopyranoside ( 1 ) and ‐trifluoromethylsulfonyl‐α‐ D 4 with malonic acid derivatives yields, via the carbanions, cyclopropa‐monosaccharides 3 6 . The ester residues attached to cyclopropane moiety can be saponified give corresponding acids which coupled new carbohydrate amino type 9 are biological interest in different immunological assays.
Reacting benzyl 2,3-anhydro-4-O-trifluoromethylsulfonyl-α-D-ribopyranoside (1) and 2,3-anhydro-4-O-trifluoromethylsulfonyl-β-L-ribopyranoside (2) with diethyl cyanomethylphosphonate the 3,4-cyclopropanated monosaccharide derivatives 3,4-(diethyl cyanomethylenephosphonate)-3,4-dideoxy-β-L-arabinopyranoside (5) (6) are obtained. The 1 H, 13 C NMR FD-MS data fully confirm suggested structures. cyclopropanated sugar of interest because their structural relation to antibiotic phosphonomycin.
Abstract The C‐terminal fragment 33–41 of thymosin β 9 is synthesized by solution synthesis, using the strategy maximum side‐chain protection with acid‐labile tert ‐butyl groups and temporary N α ‐benzyloxycarbonyl during elongation steps. Part this peptide deprotected, coupled to KLH conjugate used for production antibodies. biological activities two fragments nonapeptide are tested in our α‐amanitin‐inhibited E‐rosette assay.
