morphine). Since diffusion across a lipid bilayer requires that a drug be lipid-soluble, the ionized form of a drug cannot cross membranes. Thus, weak acids that are nonprotonated and weak bases that are protonated cannot diffuse across membranes. At a pH that is equal to a drugâs pKa, equal amounts of the protonated and nonprotonated forms are present. Assuming the pH is the same on both sides of a given membrane, the drug will be at equilibrium across the membrane.
Ledyba (Japanese: ã¬ãã£ã Rediba) is a Bug/Flying-type PokÃ©mon introduced in Generation II. Ledyba is a common Bug type PokÃ©mon that resembles a ladybug. It has six legs, that are all wearing gloves.
Generation 3. 1  Ruby - LEDYBA secretes an aromatic fluid from where its legs join its body. This fluid is used for communicating with others. 2  Sapphire - LEDYBA secretes an aromatic fluid from where its legs join its body. This fluid is used for communicating with others.
