Some novel PHA (poly [(R) -3-hydroxyalkanoate]) polymer compositions produced using biological systems are provided. A cell line expressing one or more enzymes selected from the group consisting of polyhydroxyalkanoate synthase, acyl CoA transferase, hydroxyacyl CoA transferase, and hydroxyacyl CoA synthetase is added to 3-hydroxybutyrate, 3-hydroxy Polymer accumulation by providing monomers such as propionate, 2-hydroxybutyrate, 3-hydroxyvalerate, 4-hydroxybutyrate, 4-hydroxyvalerate, and 5-hydroxyvalerate as substrates Consists of.
