As pesquisas sobre os derivados de
hexoses e pentoses tem aumentado muito desde 2004, quando um relatorio do Departamento de Energia dos EUA [40] identificou uma plataforma contendo 12 moleculas derivadas de carboidratos e seus possiveis derivados [1,4-diacidos contendo quatro atomos de carbono: acido succinico, acido fumarico e acido malico, acido 2,5-dicarboxilico furano (FDCA), acido 3-hidroxipropionico, acido aspartico, acido glucarico, acido glutamico, acido itaconico, acido levulinico, 3-hidroxibutirolactona, glicerol, sorbitol, e os alcoois derivados da xilose e da arabinose (xilitol e arabinitol)].
Comparative analysis of SGLT1 and GLUT2 transporters distribution in rat small-intestine enterocytes and Caco2 cells during
hexose absorption.
The increase of
hexoses in pods and seeds might be explained by in situ starch hydrolysis, whereas the increase in sucrose is probably due to an enhanced synthesis of this sugar for a higher osmotic adjustment.
W (1991) In vivo location of the rate-limiting step of
hexose uptake in muscle and brain tissue of rats.
Surprisingly, the species exhibited a concentration-dependent switch in sugar preference, from
hexose sugars at low concentration to sucrose at high concentrations, that was remarkably similar to that shown by specialist avian nectarivores and that contrasts with results reported for passerine occasional nectarivores.
In science,
hexose is a simple sugar with how many carbon atoms?
a m/z 449 e o fragmento do MS/MS a m/z 287 correspondem a massa molecular da aglicona cianidina, como resultado da perda neutra de uma
hexose com 162 unidades de massa atomica (u).
The ideal organism for the production of ethanol would be the one, which can utilize pentose-rich and
hexose containing sugars generated from lignocellulosic hydrolysate.
O nectar foi classificado em quatro tipos em funcao da razao sacarose
hexose-1 (S/H): sacarose dominante (S/H > 0,999), rico em sacarose (S/H de 0,5 a 0,999), rico em
hexose (S/H de 0,1 a 0,499) e
hexose dominante (S/H < 0,1) de acordo com o metodo proposto por Baker e Baker (1983).
Some of these virulence factors have easily detectable phenotypes, such as hemolysis on blood agar, PlcB phospholipase activity on egg yolk agar, and Hpt
hexose phosphate transporter activity in acidification test (2,12).
MRS reveals additional
hexose N-acetyl resonances in the brain of a mouse model for Sandhoff disease.
This is mediated by an increase in NADPH production via the
hexose monophosphate shunt.
