each RNA strand has the same basic structure, composed of nitrogenous bases covalently bound to a sugar-phosphate backbone (Figure 1). However, unlike DNA, RNA is usually a single-stranded molecule. Also, the sugar in RNA is ribose instead of deoxyribose (ribose contains one more hydroxyl grou...

The influence of the reaction time (1–6 h), temperature (120–180 °C) and the type of solvent (crude glycerol, poly(ethylene glycol)) on the process efficiency (biomass conversion), chemical structure (FTIR), hydroxyl value, water content and rheological properties was determined. In ...

A 1-deoxy-D-xylulose 5-phosphate reductoisomerase catalyzing the formation of 2-C-methyl-D-erythritol 4-phosphate in an alternative nonmevalonate pathway f... Based on analogies between electromagnetics and quantum mechanics, we introduce a method to calculate the electronic subband structure in fini...
Exploration of the hierarchical assembly space of collagen-like peptides beyond the triple helix Despite advances in machine learning approaches, de novo design of collagen-based materials remains difficult. In this study, based on the natural structure of the defense collagen family of proteins, desi...
Prebiotic systems chemistry suggests that high phosphate concentrations were necessary to synthesise molecular building blocks and sustain primitive cellular systems. However, current understanding of mineral solubility predicts negligible phosphate concentrations for most natural waters, yet the role of Fe2+, ...
