Affinity of Tannins to Cellulose: A Chromatographic Tool for Revealing Structure-Activity Patterns

نویسندگان

چکیده

Food, feed and beverage processing brings tannins into contact with macromolecules, such as proteins polysaccharides, leading to different chemical physical interactions. The interactions of are well known but less is about the affinity polysaccharides. We used bacterial cellulose from nata de coco a model compound investigate how interact by adsorption measurements using UPLC-DAD. also explored structure influences these included nine individual structurally hydrolysable (HTs) eight well-defined proanthocyanidin (PA) fractions monomeric units, mean degree polymerization both A- B-type linkages. Tannins were found have strong weak cellulose, depending on exact tannin. For HTs, main structural features affecting flexibility HT molecule number free galloyl groups. PAs, prodelphinidins higher than procyanidins. Similarly presence groups in galloylated PAs PA led stronger interaction. Adsorption UPLC-DAD proved be sensitive rapid tool evaluate cellulose.

Tannins of Constant Structure in Medicinal and Food Plants—Hydrolyzable Tannins and Polyphenols Related to Tannins

In addition to the commonly used classification as hydrolyzable tannins and condensed tannins, tannins can also be categorized into two other types: polyphenols of constant chemical structure (Type A) and polyphenols of variable composition (Type B). Both types of tannins and related polyphenols account for a large part of plant polyphenols, but accurate structure-activity correlations on a mol...

Revealing the Changing Spatial Structure of Cities from Human Activity Patterns

Identifying changes in the spatial structure of cities is a prerequisite for the development and validation of adequate planning strategies. Nevertheless, current methods of measurement are becoming ever more challenged by increasingly dispersed forms of urban organisation. Being motivated by the recent availability of large-scale data on human activities, this paper proposes a new quantitative...

Revealing centrality in the spatial structure of cities from human activity patterns

Identifying changes in the spatial structure of cities is a prerequisite for the development and validation of adequate planning strategies. Nevertheless, current methods of measurement are becoming ever more challenged by the highly diverse and intertwined ways of how people actually make use of urban space. Here, we propose a new quantitative measure for the centrality of locations, taking in...
