Reduces Risk of Birth Defects For pregnant women, B12 is critical to a babys neurological development
In 1981, Lubert Stryer (19382024) emphasized that protein molecules are not inflexible crystal-like entities, but are characterized by very rapid motions of selected regions, since nanosecond fluorescence polarization analysis revealed that segmental flexibility, where domains can rotate over an appreciable angular range of times of nanoseconds, is a characteristic feature of multidomain proteins, whereas time-resolved fluorescence polarization studies have demonstrated that internal tryptophan residues can be flexible in the subnanosecond time range (Stryer, 1981)
Furthermore, the analysis of the frictional ratio for casein provided early insights into the non-globular and flexible nature of the casein molecule (Svedberg and Pedersen, 1940)
