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.
Insulin Syringes can not be used in place of a Tuberculin Syringe because the units of measure are different and the needle of a TB Syringe is shorter than that of an Insulin Syringe.he width of the needle is known as the needle gauge. The higher the number of the needle gauge, the thinner the needle. These syringes are marked in increments of 0.01 cc. And the needles are often 26 to 27 gauge in diameter and 1/2 to 5/8 inch in length.
