0.2-g sample of amylopectin was analyzed to determine the frac- tion of the total glucose residues that are branch points in the struc- ture. the sample was exhaustively methylated and then digested, yielding 50 mol of 2,3-dimethylglucose and 0.4 mol of 1,2,3,6- tetramethylglucose. a. what fraction of the total residues are branch points? b. how many reducing ends does this sample of amylopectin have?

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
