All amino acids that are found in proteins, except for proline, contain a(n); Group of answer choices amino group carbonyl group
Jobisdone [24]

Answer:

amino group

Explanation:

There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.

Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.

Calculate the change in the standard entropy of the system, delta s degree for the synthesis of ammonia from N_2(g) and H_2(g) a
Svet_ta [14]

Answer:

\Delta S^{0} for the reaction is -198.762 J/K

Explanation:

N_{2}(g)+3H_{2}(g)\rightarrow 2NH_{3}(g)

Standard change in entropy for the system (\Delta S^{0}) is given by-

\Delta S^{0}=[2moles\times S^{0}(NH_{3})_{g}]-[1mole\times S^{0}(N_{2})_{g}]-[3\times S^{0}(H_{2})_{g}]

where S^{0} represents standard entropy.

Here S^{0}(NH_{3})_{g}=192.45J/(K.mol), S^{0}(N_{2})_{g}=191.61J/(K.mol) and S^{0}(H_{2})_{g}=130.684J/(K.mol)

So, \Delta S^{0}=[2\times 192.45]-[1\times 191.61]-[3\times 130.684]J/K=-198.762J/K
