Protonation and ring closure of stereoisomeric alpha-substituted cinnamic acids in superacidic media studied by 13C NMR spectroscopy and computations [PDF]

open access: yes, 1998
Five alpha-substituted cinnamic acids [(E)- and (Z)-2,3-diphenyl-, (E)- and (Z)-3-(2-methoxyphenyl)-2-phenyl- and (E)-2-(2-methoxyphenyl)-3-phenyl-propenoic acids] have been protonated in fluorosulfonic acid at -78 degrees C, Protonation of the ...

Empiric mathematical model for predicting the content of alpha-acids in hop (Humulus lupulus L.) cv. Aurora

open access: yesSpringerPlus, 2013
The aim of this research is to find a simple mathematical model due to sum of effective temperatures and rainfalls from second germination after spring pruning till the technological maturity of hop cones, in order to achieve reliable prognosis of alpha ...

The Czech hop hybrid variety - Part I.

open access: yesKvasný průmysl, 2013
The Vital hop variety was first registered in 2008. Vital is genetically most related to Agnus, another Czech variety. The yield potential is 2.0 to 2.5 t/ha. With respect to its content of α-bitter acids of 10 to 15 % it belongs to the bitter cultivars.

Evaluation of variability of the content of alpha and beta acids in Czech bittering hop varieties (Humulus lupulus L.)

open access: yesKvasný průmysl, 2023
Czech bitter varieties were evaluated between 2010 and 2022. Hop varieties displayed an average content of alpha acids between 10.24% w/w (Agnus) and 13.73% w/w (Gaia).

Tetrahydro iso-Alpha Acids from Hops Improve Glucose Homeostasis and Reduce Body Weight Gain and Metabolic Endotoxemia in High-Fat Diet-Fed Mice

open access: yesPLoS ONE, 2012
Obesity and related metabolic disorders such as insulin resistance and type 2 diabetes are associated with a low-grade inflammatory state possibly through changes in gut microbiota composition and the development of higher plasma lipopolysaccharide (LPS)

Complexation between oleanolic and maslinic acids with native and modified cyclodextrins [PDF]

open access: yes, 2018
Oleanolic (OA) and maslinic (MA) acids are two natural triterpenoids with a wide range of beneficial effects for human health. However, their low solubility and permeability make their application in the food or industry difficult. The complexation of OA

Dual Effects of Alpha-Hydroxy Acids on the Skin

open access: yesMolecules, 2018
AHAs are organic acids with one hydroxyl group attached to the alpha position of the acid. AHAs including glycolic acid, lactic acid, malic acid, tartaric acid, and citric acid are often used extensively in cosmetic formulations.

VITAL - The Czech hop hybrid variety - Part II.

open access: yesKvasný průmysl, 2013
In the last few years brewing tests with hop products of the Vital variety (hop pellets T90 and a CO2-extract) were carried out at different levels: from a pilot scale trial to a full scale trial.

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

open access: yes, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...

The effect of hop beta acids oxidation products on beer bitterness.

open access: yesKvasný průmysl, 2013
Instability and tendency to oxidation depending on conditions is a dominant property of hop beta acids . This property has an impact on both the hop storage and the beer brewing process . Approximately one half of the amount decomposes in the air at room
