Journal of Separation Science, Volume 49, Issue 7, July 2026.ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...

Occurrence of Pterin Pigments in Hymenoptera [PDF]
Nature, 1950 IT has been found that pterins exist in tissues of animals belonging to nearly all groups; their occurrence as pigments, however, is restricted to insects and cold-blooded vertebrates1,2. Among Lepidoptera, they are always present in the wing-scales of the Pieridae and appear to be a biochemical characteristic of that natural family3,4.

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4577-4598, July 2026.ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Biochemistry and biosynthesis of insect pigments
European Journal of Entomology, 2014 The functional role and commercial importance of insect pigments have been studied for well over a century. They are classified into those synthesized by insects, which include anthraquinones, aphins, pterins, tetrapyrroles, ommochromes, melanins and ...

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.

Tetrahydrobiopterin (Bh4) deficiencies: diagnosis and treatment
Acta Pediátrica de México, 2014 Tetrahydrobiopterin (BH4) is an enzyme cofactor of phenylalanine hydroxylase, tyrosine hydroxylase and tryptophan hydroxylase. Three different enzymes affect BH4 synthesis: guanosine triphosphate cyclohydrolase I (GTP CH 1), 6-piruvoil tetrahydropterin ...

Ultraviolet-induced fluorescent imaging for millipede taxonomy [PDF]
Research Ideas and Outcomes, 2017 Fluorescent imaging has been traditionally applied to cell biology, and more recently to entomology to capture microscopic images of insect anatomy. However, the technique has not been applied to the study of millipedes, most of which autofluoresce as a ...

Capture‐SELEX of DNA Aptamers for Highly Selective Binding of Folate
ChemBioChem, Volume 27, Issue 10, 27 May 2026.Using capture‐SELEX, a DNA aptamer with sub‐micromolar affinity for folate was isolated, showing excellent selectivity. Using this aptamer, a light‐up fluorescent biosensor was developed for folate detection. Folate (vitamin B9) is an essential micronutrient for human health, particularly during pregnancy.

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.
