and some are negatively charged. In a properly folded protein, hydrophobic amino acid residues are together, shielding each other from water molecules; hydrophilic residues are exposed on the ...

The adenine portion of ATP is sandwiched between aromatic and hydrophobic amino acid residues, with its negatively charged ...

Lyophilization (freeze-drying) is commonly utilized to support peptide stability. Removing water from peptide solutions might significantly reduce hydrolysis and deamidation rates. Lyophilized ...
