Biochemical analyses of sugary-1 mutants indicate that both types of starch debranching enzymes, isoamylase and pullulanase, are either missing or greatly reduced in the endosperms of maize (Pan and Nelson, 1984; Rahman et al., 1998) and rice (Nakamura et al., 1992, 1996b, 1997, and the present study).he present investigation has been carried out to examine the relationship between the activities of starch debranching enzymes and the alteration of amylopectin structure in various sugary-1 endosperms of rice by partitioning the endosperm into the starch region and the phytoglycogen region.
Insulin Syringes. An insulin syringe has three parts: a needle, a barrel, and a plunger. The needle is short and thin and covered with a fine layer of silicone to allow it to pass through the skin easily and lessen pain. A cap covers and protects the needle before it is used. The barrel is the long, thin chamber that holds the insulin.
