Chitlac is a biocompatible modified polysaccharide composed of chitosan backbone to which lactitol moieties have been chemically inserted via reductive N-alkylation reaction with lactose. The physical-chemical and biological properties that already reported in the literature suggest high accessibility terminal galactose side chain. This finding may account for its biocompatibility makes it extremely interesting production biomaterials. average structure dynamics chains studied by means NMR...
The objective of this work was to determine the influence soil substrate on characteristics and properties a specific type honey. As such, we analysed features typical single-flower honey, thyme produced in Mediterranean region. Thymus is genus aromatic perennial plants that are native Europe, North Africa Asia. A total 70 honey samples from hives situated limestone (38 samples) or gypsum soils (32 were studied. physical chemical each analyzed using standard assays. Within same geographical...
Honey samples (n = 126) from Castilla-La Mancha (Central Spain) were characterized based on their physicochemical properties and a melissopalynological analysis. The latter showed that Echium pollen type was the dominant palynomorph in most samples, representing at least 30% of each sample. As anticipated, relationship observed between proportion this honey. One goal study to set threshold defines percentage necessary for Viper's bugloss honey be considered monofloral or multifloral. This is...
Gypsophila bermejoi G. López is an allopolyploid species derived from the parental struthium L. subsp. and tomentosa All these plants are gypsophytes endemic to Iberian Peninsula of particular ecological, evolutionary biochemical interest. In this study, we present evidence a possible repression on process speciation by climatic factors. We modelled ecological niches three taxa considered here using maximum entropy approach employing series bioclimatic variables. Subsequently, projected...
Abstract Chitosan and its highly hydrophilic 1‐deoxy‐lactit‐1‐yl derivative (Chitlac) are polysaccharides with increasing biomedical applications. Aimed to unravel their conformational properties we have performed a series of molecular dynamics simulations Chitosan/Chitlac decamers, exploring different degrees substitution (DS) lactitol side chains. At low DS, two regions populations visited, while for DS ≥ 20% the oligomers remain mostly linear only one main region glycosidic angles is...
Climate change has altered the global distribution of many species. Accordingly, we have assessed here potential shift in Gypsophila bermejoi G. López under distinct scenarios future climate change, this being a species endemic to Iberian Peninsula. For strict gypsophiles, climatic changes affecting their area could be critical if new range is not overlapped with suitable soils. Thus, narrow bioclimatic niche and nature plant make particularly vulnerable change. We used Maximum Entropy...
Two new sulfated saponins (1 and 2) were isolated from a butanol-soluble extract of the roots Gypsophila bermejoi identified by combination chemical degradation spectral methods as 3β-sulfate ester gypsogenin 28-O-β-d-glucopyranosyl(1→2)-[β-d-glucopyranosyl(1→6)]-β-d-glucopyranoside (1), 23-sulfate hederagenin (2), respectively. Plants genus (Caryophyllaceae) are important industrially because capacity their saponin constituents to behave like natural detergents.1 Saponins this based on...
Crude extracts of Spanish plants (60 representing 12 species from 7 families) have been screened for antiparasitic activity against Leishmania infantum and Trichomonas vaginalis. 30% the showed one parasites 15% were active both tests organisms. The most promising originate used in traditional medicine, such as Inula montana L. (Asteraceae), Bupleurum rigidum (Apiaceae) Scrophularia scorodonia (Scrophulariaceae).
Several species of the Gypsophila genus are endemic to Iberian Peninsula, including gypsophytes particular ecological, evolutionary and biochemical interest, taxa that have undergone both sympatric allopatric genetic differentiation. The niche shift among these has been assessed using ecological modelling ordination techniques, adopting a overlap approach compare similarity equivalency niches. We used Maximum Entropy method study potential distribution in different eras: Last Glacial (LGM),...
The range of pollen that can be found around the city Sigüenza has been analysed (La Alcarria, north-eastern region, Guadalajara, Spain), an area currently included in territory comprising Protected Origin Denomination 'Miel de la Alcarria'. We studied recovered from two different types biological sensors: bryophytes, live material used to study recent rain, and honey. aim this was try establish relationship between collected both sensors existing natural vegetation using comparative...
Polyploidy has been an influential force in plant evolution, playing a crucial role diversification. Differences polyploid and diploid distributions have long noted, with taxa especially abundant harsh environments. These plants higher photosynthetic rates and/or tolerance to water deficits. Moreover, there is data pointing increase the rate of unreduced gamete formation by under conditions stress. Accordingly, frequency individuals would be expected populations living extreme environments,...
