In the eusocial honey bee Apis mellifera, with reproductive queens and sterile workers, a female larva's developmental fate depends on its diet; nurse bees feed queen-destined larvae exclusively royal jelly, a glandular secretion, but worker-destined larvae receive royal jelly for 3 days and subsequently jelly to which honey and beebread are added. RNA-Seq analysis demonstrated that p-coumaric ...

The metabolism of flavone C-glucosides and p-coumaric acid from antioxidant of bamboo leaves (AOB) in rats is discussed systematically in the present study. Following single oral administration of AOB, p-coumaric acid was detected in plasma but not in gastrointestinal tract extracts and faeces, and the corresponding absorption pharmacokinetic curve at different time points showed a prolonged el...

Phenolic compounds in loquat fruit were identified as 5-caffeoylquinic acid (chlorogenic acid), neochlorogenic acid, hydroxybenzoic acid, 5-p-feruloylquinic acid, protocatechuic acid, 4-caffeoylquinic acid, epicatechin, o-coumaric acid, ferulic acid, and p-coumaric acid. Neochlorogenic acid was found to be dominant in the early stages of loquat fruit development. Both the concentrations and typ...

Hydroxycinnamic acid derivatives (HCAs) are a group of naturally occurring polyphenolic compounds which possess various pharmacological activities. In this work, the interactions of bovine serum albumin (BSA) with six HCA derivatives, including chlorogenic acid (CHA), caffeic acid (CFA), m-coumaric acid (m-CA), p-coumaric acid (p-CA), ferulic acid (FA) and sinapic acid (SA) have been investigat...

Natural Crosslinkers In article number 2212325, Byong-Taek Lee and coworkers develop a highly functional wound dressing using acellular marine kelp crosslinked ECM proteins p-Coumaric acid (p-Cou). Incorporating p-Cou accelerates the healing mechanisms maintains unique pH balance of biomaterial. The study is noble approach toward preparation materials analyzing their functionality by combining ...

Natural phenolic acids are commonly present in plants consumed in the diet. Recently we have observed that different natural phenolic acids exert differential effects on the body mass gain in ovariectomized and non-ovariectomized female rats. The aim of the present study was to investigate the effects of ferulic, caffeic, p-coumaric and chlorogenic acids on serum estradiol and total cholesterol...

To explore the effects of harvest time on phenolic compounds during wine fermentation, grape berries (Vitis vinifera L. cv. Vidal) were harvested at 17.5, 22.8 and 37.2 masculine Brix and were used to make dry wine, semi-sweet wine and icewine with low alcohol levels, respectively. Phenolic acids and flavan-3-ols were assayed during the fermentation of wines by means of reverse phase-high perfo...

Micro-organisms have been isolated that can utilize o-coumaric acid as a sole carbon source with the subsequent production of 4-hydroxycoumarin and dicoumarol. One of these organisms, Penicillium jenseni, has been used to examine the biosynthesis of dicoumarol. Certain thermophilic fungi have also been found that can convert o-coumaric acid into dicoumarol.
