WebThe polymerization of deoxyhemoglobin S allows the acceptor pocket of one tetramer to bury the mutant βVal-6 within the lateral contact. This removes the hydrophobic residue from most solvent interactions. This lateral contact site has great hydrophobicity but also has a well-established network of ordered water molecules. WebThe term hydrophobicity was derived from two Greek words that are hydro that means water and phobos that means fear; thus, hydrophobic surfaces can be define as …
WebDec 7, 2024 · Grape seed extract (GSE) displays strong antioxidant activity, but its instability creates barriers to its applications. Herein, three HP-β-CD/GSE inclusion complexes with host–guest ratios of 1:0.5, 1:1, and 1:2 were successfully prepared by co-precipitation method to improve stability. Successful embedding of GSE in the HP-β-CD cavity was … WebThe hydrophobicity was calculated as follow. Hydrophobic rate ( %) = ( Aa − Ab) / Aa × 100 % Where Aa is the initial absorbance at 600 nm, and Ab is the absorption value after …
