    Its linked by an ester bond.

    TAG contains glycerol and 3 fatty acids linked by an ester bond. and This is the most common storage form of Fatty Acids.

    hi..well, even i thought of this answer, bcoz intracellular K concentration vil directly b affected by aldosterone which is a steroid, but insulin also helps in increasing cellular uptake of K, thus increasing its concentration in the cells..and insulin is a polypeptide..so, i m really not sure...correct me if i m wrong..thanx..
