CircRNA May Not Be “Circular”

Frontiers in Genetics, 2021
Circular RNA (circRNA) is a novel regulatory non-coding RNA and participates in diverse physiological and pathological processes. However, the structures and molecular mechanisms of circRNAs remain unclear.

Relationship between Oversulfation and Conformation of Low and High Molecular Weight Fucoidans and Evaluation of Their in Vitro Anticancer Activity

Molecules, 2010
Low and high molecular weight fucoidans (F5-30K and F>30K) were chemically modified through the addition of sulfate groups, and the effect of oversulfation on the in vitro anticancer activity was investigated. After the addition of sulfate groups,

Molecular Gas Phase Conformational Ensembles

Journal of Chemical Information and Modeling, 2023
Abstract. Accurately determining the global minima of a molecular structure is important in diverse scientific fields, including drug design, materials science, and chemical synthesis. Conformational search engines serve as valuable tools for exploring the extensive conformational space of molecules and identifying energetically favorable conformations.

A supramolecular proposal of lignin structure and its relation with the wood properties

Anais da Academia Brasileira de Ciências, 2009
In spite of the great importance of cellulose the lignin is considered the second most abundant substance of the wood. However, little attention has been given it, mainly to wood properties. The lignin as well as other structural compounds (cellulose and
