    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.

    thanx dr dent..

    1) Each of the following can be increased by polypeptide hormones except

    a.Inositol triphosphate concentration
    b. Intracellular Ca concentration
    c. Intracellular K concentration
    d. Adenylate cyclase activity
    e. Protein kinase C activity

    2) Touch receptors per unit area in mucosa are max. in
    a. uvula
    b. hard palate
    c. attached gingiva
    d. tip of tongue
    e. buccal/labial vestibule

    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..
