It is given that a protein has a molecular weight (Mw) of 21342. It consists of 180 amino acids of which 80 are glutamine (Mw of anhydro residue = 128.1), 60 are histidine (Mw of anhydro residue 137.2) and 40 alanine (Mw of anhydro residue 71.1). At both the C-terminal and the N-terminal position an alanine residue is present.

Which best describes why nh4+ can form an ionic bond with ci-?

What is the subscript for oxygen in its molecular formula

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
