The enzymatic hydrolysis of meso-1,7-diacetoxy-2,6-dimethylheptane 5, prepared from 2,6-dimethylhepta-1,6-diene 6, gave the (2S,6R)-7-acetoxy-2,6-dimethyl-1-heptanol 1, which was transformed to the (2R,6R)-2,6,10-trimethyl-1-undecanol 7. In this manner, the C14 side chain of a-Tocopherol was synthesized from 2,6-dimethylhepta-1,6-diene 6 in only 5 steps.

There is a significant potential to increase the sustainability of fishing and aquaculture industries through maximization processing byproducts. Enzymatic hydrolysis provides an opportunity valorize downstream fish industry byproducts for production protein hydrolysates (FPH) as source bioactive peptides (BAP) with health benefits. Deteriorative oxidative reactions may occur during enzymatic b...

BACKGROUND The recalcitrance of softwood to enzymatic hydrolysis is one of the major bottlenecks hindering its profitable use as a raw material for platform sugars. In softwood, the guaiacyl-type lignin is especially problematic, since it is known to bind hydrolytic enzymes non-specifically, rendering them inactive towards cellulose. One approach to improve hydrolysis yields is the modification...

the objective of this study was to produce fish protein hydrolysate (fph) with the most antioxidant activity, by enzymatic hydrolysis from (carassius carassius). the protein of crucian carp a low value fish was hydrolyzed by alcalase 2.4l and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (rsm) by the central rota...

The ever-increasing global demand for energy and materials has a pronounced effect on worldwide economic stability, diplomacy, and technical advancement. In response, a recent key research area in biotechnology has centered on the biological conversion of lignocellulosic biomass to simple sugars. Lignocellulosic biomass, converted to fermentable sugars via enzymatic hydrolysis of cell wall poly...

Correction for ‘Non-catalytic proteins as promising detoxifiers in lignocellulosic biomass pretreatment: unveiling the mechanism enhanced enzymatic hydrolysis’ by Meysam Madadi et al. , Green Chem. 2023, https://doi.org/10.1039/d3gc01718d.

In studies of the inhibition in viva of animal viruses by poly-n-lysine, Rubini et al. (1) and Green et al. (2-4) obtained data which suggested that poly-L-lysine is hydrolyzed by the proteolytic enzymes of the allantoic fluid, and that this enzymatic hydrolysis may limit its biological activity. The enzymatic hydrolysis of poly-n-lysine was reported by Katchalski (5) and by Waley and Watson (6...

Characterization, understanding and overcoming barriers of enzymatic hydrolysis of different raw materials is essential for the development of economically competitive processes based on enzymatic treatments. This work focused on factors relevant for the improvement of enzymatic hydrolysis of lignocellulose raw materials derived from softwood. The major interest of the work was in lignin. Speci...

The biochemical conversion of cellulosic biomass to ethanol, a promising alternative fuel, can be carried out efficiently and economically using the simultaneous saccharification and fermentation (SSF) process. The SSF integrates the enzymatic hydrolysis of cellulose to glucose, catalyzed by the synergistic action of cellulase and beta-glucosidase, with the fermentative synthesis of ethanol. Be...
