What's the difference between fad and sad?

Fad


Definition:

  • (3) RR spectra of fatty acyl-CoA and its complexes are consistent with the previous hypothesis that visible spectral shifts observed during formation of acetoacetyl-CoA and crotonyl-CoA complexes of fatty acyl-CoA dehydrogenase result from charge-transfer interactions in which the ground state is essentially nonbonding as opposed to interactions in which complete electron transfer occurs to form FAD semiquinone.

  • (13) Thus, ETF appears to contain one flavin (at least 90% FAD, by chromatographic and fluorescence characteristics) per 26,000 M-r, and therefore may be composed of two subunits with one flavin each.
  • (14) Microcoulometric titrations of NADH:nitrate reductase at 25 degrees C in Mops buffer, pH 7.0, showed that the native enzyme, containing functional FAD, haem and Mo, required addition of five electrons for complete reduction.

  • (17) It had been shown that thyroxine regulates the conversion of riboflavin to riboflavin mononucleotide and flavin adenine dinucleotide (FAD) in laboratory animals.
  • (18) The value of P of the enzyme is dependent on its concentration, indicating that the degrees of dissociation of FAD in the monomer and dimer are different.
  • (19) We now provide evidence for a major early onset FAD locus on the long arm of chromosome 14 near the markers D14S43 and D14S53 (multipoint lod score z = 23.4) and suggest that the inheritance of FAD may be more complex than had initially been suspected.
  • (20) Thus, the low activity resulting from an inherited deficiency of FAD is decreased further.
