1. NEAR INFRARED SPECTROSCOPY: RAPID AND ACCURATE ANALYTICAL TOOL FOR PREDICTION OF NON-STRUCTURAL CARBOHYDRATES IN WOOD
ABSTRACT The non-structural carbon reserves in the various organs of trees are associated with their growth and the mechanism of resilience when exposed to environmental stresses, especially the water deficit. The goal of this study was to develop multivariate models to estimate the amount of non-structural carbohydrates (starch, sucrose, reducing sugars, to

2. Structural Organization of Dental Biofilm Formed in situ in the Presence of Sucrose Associated to Maltodextrin
Resumo Maltodextrinas, derivadas do amido de milho, tem sido adicionadas a alimentos industrializados combinadas à sacarose. Entretanto não estão esclarecidas as propriedades de difusão na matriz do biofilme dental e a estrutura tridimensional de biofilmes multiespécies formados na presença destes carboidratos. Portanto o objetivo deste estudo foi aval

3. Synthesis and Antimicrobial Activity of Glycosylated 2-Aryl-5-amidinobenzimidazoles
A series of new glycosylated 2-aryl-5-amidinobenzimidazoles derived from four different carbohydrates (D-glucose, D-galactose, N-acetyl-D-glucosamine and lactose) were synthesized by the condensation of the appropriate 4-formyl-3-methoxyphenyl glycoside with 4-amidino- or 4-N-isopropylamidino-ortho-phenylenediamine hydrochloride. All the compounds were prope

4. Physicochemical, structural and thermal properties of oxidized, acetylated and dual-modified common bean (Phaseolus vulgaris L.) starch
Abstract Common beans are rich in protein and complex carbohydrates that are valuable for the human diet. Starch is the most abundant individual component; however, in its native form it has limited applications and modifications are necessary to overcome technological restrictions. The aim of this study was to evaluate the influence of oxidation, acetylatio

5. Aggregate Stability in Soil with Humic and Histic Horizons in a Toposequence under Araucaria Forest
ABSTRACT Aggregate stability is one of the most important factors in soil conservation and maintenance of soil environmental functions. The objective of this study was to investigate the aggregate stability mechanisms related to chemical composition of organic matter in soil profiles with humic and histic horizons in a toposequence under Araucaria moist fore

6. Structural diversity and biological importance of ABO, H, Lewis and secretor histo-blood group carbohydrates
ABSTRACT ABO, H, secretor and Lewis histo-blood system genes control the expression of part of the carbohydrate repertoire present in areas of the body occupied by microorganisms. These carbohydrates, besides having great structural diversity, act as potential receptors for pathogenic and non-pathogenic microorganisms influencing susceptibility and resistanc

7. Aggregation agents and structural stability in soils with different texture and organic carbon contents
The flat pampas in the state of Santa Fe in Argentina have soils with high silt content, variable carbon content, and diverse degrees of structural degradation. Aggregate stability has been used as an indicator of the structural condition of the soil. This study aimed to quantify the effect of the addition of crop residues and root activity on the agents of

8. Seasonal changes in fructan accumulation in the underground organs of Gomphrena marginata Seub. (Amaranthaceae) under rock-field conditions
Rock field plant species present several adaptations to the climatic characteristics and seasonality of this habitat. In this study, we evaluate under field conditions the seasonal changes in non-structural carbohydrate accumulation in tuberous organs of Gomphrena marginata. Tuber fragments of plants of G. marginata were sampled monthly for a year (August 20

9. Estudo das características estruturais e das propriedades funcionais do amido de sementes de jaca (Artocarpushete-rophylusLam) variedades mole e dura.
Starch is a polysaccharide used as a source of carbohydrates in the human diet, with wide application in food industry, textile and pharmaceutical industries. The search for new sources starch is growing, causing the production sector is seeking new technologies, as well as natural starches with different chemical and physical characteristics. The objective

10. Análise estrutural do domínio de reconhecimento a carboidratos da lectina Dvirl de Dioclea virgata e sua correlação na indução da produção de óxido nítrico / Structural analysis of the carbohydrate recognition domain the DvirL lectin from Dioclea virgata and its correlation in the induction of nitric oxide production
Lectins are defined as proteins or glycoproteins of nonimmune origin that have at least one site of reversible binding to carbohydrates or glycoconjugates. Lectins of plant origin are the most studied and characterized as three-dimensional structure and biological functions related. Lectins can be found in different parts of the plant from its root to the in

11. A importância estratégica do potássio para o Brasil.
ABSTRACT: This paper presents the strategic importance of potassium (K) in Brazil, focusing four aspects: the function in the plant; the K content of Brazilian soil; the different K forms; and its demand in the Brazilian agricultural system. The K is not a structural element of plants, but it participates in many biochemical plant processes, like carbohydrat

12. Caracterização bioquímica e histo-estrutural de embriões de Inga vera Willd. Subsp. affinis (DC.) T.D. Penn. durante a maturação e após secagem / Biochemical, histological and structural characterization of Inga vera Wild. Subsp. Affinis (DC.) T.D. Penn. seeds during maturation and after drying
Inga vera Pennington produz sementes com alta sensibilidade à dessecação, o que dificulta seu armazenamento. Diversos mecanismos estão relacionados tolerância à dessecação, dentre eles o acúmulo de reservas insolúveis e de moléculas protetoras, redução do metabolismo e dobramento da parede celular. Desse modo, o objetivo deste trabalho foi anali
