Response of an Infant With Presumed Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) to Ketone Supplementation

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in one of three known genes: ETFA, ETFB, and ETFDH. It can cause multisystem dysfunction, including cardiomyopathy in severe cases.

Exploring the mechnisms of molecular recognition by flavins

open access: yes, 2005
The design and development of chemical models for enzymes depends on the fundamental principles observed in biological systems. Molecular recognition of flavins by various receptors has attracted attention due to their applications as chemical models for

Ultrafast excited-state deactivation of flavins bound to dodecin

open access: yes, 2021
Dodecins, a group of flavin-binding proteins with a dodecameric quaternary structure, are able to incorporate two flavins within each of their six identical binding pockets building an aromatic tetrade with two tryptophan residues.

SURFACE-ENHANCED RAMAN SPECTROSCOPY OF FLAVINS AND FLAVOPROTEINS

open access: yes, 1986
Address of Lee and Morris: Department of Chemistry, University of Michigan, Ann Arbor, MI 48109.Author Institution:The N(3) anions of flavins are shown to be responsible for surface enhancement of Raman spectra on silver colloids.

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

open access: yesAdvanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

FLAVIN-HYPOXANTHINE DINUCLEOTIDE

open access: yesTHE JOURNAL OF VITAMINOLOGY, 1957
1. FHD was synthesized from FAD by deamination with nitrous acid and the product was first isolated as barium salt. The yield and purity were, however, unsatisfactory by this method. Therefore, the product was extracted with cresol, followed by transfer in aqueous phase, and by subjecting to column chromatography, FHD was obtained in high purity in ...

Inflammation‐driven variability in drug metabolism: Insights from voriconazole treatment of HSCT recipients

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Voriconazole is commonly used to prevent fungal infections after haematopoietic stem cell transplantation (HSCT). Although its metabolism is influenced by CYP2C19 genetics and inflammation, their combined effect is rarely considered in clinical practice, and integrated analyses remain limited.

Why Flavins Are not Competitors of Chlorophyll in the Evolution of Biological Converters of Solar Energy

open access: yes, 2012
Excited flavin molecules can photocatalyze reactions, leading to the accumulation of free energy in the products, and the data accumulated through biochemical experiments and by modeling prebiological processes suggest that flavins were available in the ...

Physiologically‐based pharmacokinetic modelling of uridine 5′‐diphosphoglucorosultransferase (UGT) substrate drugs in pregnant women

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims While pregnancy‐related changes in phase I enzyme activity are well‐documented, less is known about the impact on phase II enzymes. This study aimed to test the hypothesis that changes in the pharmacokinetics (PK) of uridine 5′‐diphosphoglucuronosyltransferase (UGT) substrates during pregnancy result from altered enzyme expression or activity ...
