Abstract:
... There were two purposes for this investigation: 1) determine if S- and/or R-equol is present in seven plant-based food products and 2) to establish if topical or oral R/S equol administration improved skin health in adult men. First, the presence of R- and/or S-equol was determined by high performance liquid chromatography (HPLC) in commercial food products. Next, in a small pilot study R/S equol ...

Abstract:
... The formation of hydrates of inorganic compounds is well known and is widely discussed in the contemporary literature. The reasons for the insufficiently detailed characterization of numerous well-known hydrates of organic compounds are analyzed, the main of which is their instability. The CAS numbers assigned to many of these hydrates confirm interest in these hydrates. We found that the reversib ...
