An octapeptide composed of four repeating glycylalanyl units has one free amino group on a glycyl residue and one free carboxyl group on an alanyl residue. Please draw structure and explain

Following are the solution to this question:

Explanation:

The octapeptides are:

Its structure includes free glycine amino, and alanine residues free carboxylic. Its peptides are customarily extracted from the left side free NH2 residues as well as the right side free -COOH residues only in the same direction, the sequence is provided.

please find the structure in the attached file.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
