that binding the hydroxyl of the
carboxyl and one hydrogen of the aminis lost resulting in the liberation of one e
water molecule.
- What is the binding
between two amino acids
called?
The chemical boacids is called a peptide bond.nd between two amino
- Do the –R groups bound to
the central carbons participate
in the union between amino
acids?
The peptide bond attachesof the amine group of one amino acid the nitrogento (^)
the carbon of the carboxyl group ofanother amino acid liberating one
molecule of water. So the –R groups do
not participate in that bond.
- Do the –H groups bound to
the central carbons participate
in the peptide bond?
The central carbgroups and the hydrogens attached toons themselves, the –R
the central carbons do not participate in
the peptide bond.
- Do the amine and the
carboxyl groups attached to
central carbons participate in
the union between amino
acids?
Yes. The nitrogen of the amione amino acid binds to the carbon ofne group of
the carboxyl group of the other amino
acid. Tthe formation ohe water mf the peptide bond thusolecule liberated from
has a hydrogen from the amine and an
oxygen and another carboxyl. hydrogen from the - Does the chemical reaction
to unite amino acids
incorporate or liberate atoms?
What are the chemical entities
incorporated or liberated in
this reaction?
The union of amino acids by peptide
bond liberates atoms. Thas constituents of one moleculey are liberatede of
water. - Are there different
proteins made by the same
total number of amino acids?
Different proteins with thnumber of amino acids may ee same totalxist. In
such cases the differentiationby the types of amino acids or is givenby the
sequence in which thprotein. ey form the
