When two amino acids are linked together to form a peptide bond what is removed?
A water molecule
What molecule is removed during the formation of new bonds within a polypeptide?
During the formation of new bonds within a polypeptide, a molecule of water (H2O) is removed. This process is known as dehydration synthesis or condensation reaction, in which a hydroxyl (OH) group is removed from one amino acid and a hydrogen (H) atom is removed from the adjacent amino acid, resulting in the formation of a peptide bond.
What is another way of describing a dehydration synthesis reaction?
A hydroxyl group is removed from one molecule, a hydrogen atom from another molecule, and the two molecules are joined together to form a larger molecule. The OH and H combine together to form a water molecule. Therefore, dehydration synthesis involves removing a water molecule from two molecules (dehydration) in order to form a larger molecule (synthesis). This can be seen in many polymerization reactions, such as in forming a polypeptide from several amino acids. In this particular case, the OH is removed from the carboxyl group of one amino acid, and an H is removed from the amino group of another amino acid. The two amino acids are joined together in a dipeptide bond, and a water molecule is formed from the OH and H that were removed.
What kind of bonds hold amino acids together to make proteins?
A special form of amide bond called peptide bonds.
What is amino- sulfate?
What is amino sulphate
Which atoms in all of the amino acids frin the amino portion of the molecule?
MATT JONES has rabies!!
What is the unique portion of amino acids called?
R group.
When amino acids are oxidized to form cellular energy their amino groups are removed and liberated as?
Urea
What does the liver removed from the blood?
amino acids and glucose A+
Are amino acids steroids?
No. Amino acids are the building blocks of proteins, while steroids form just a portion of the hormone family.
The process by which amino groups are removed from proteins is called?
Deamination
What bonds form when water is removed?
peptide amino
Which atoms in all of amino acids form the 'amino' portion of the molecule?
matt jones cut his butt hole shaving it last week!!
What portion of a tRNA molecule determines the type of amino acid that bonds with the tRNA?
The Anticodon.
When amino acids are oxidized to form cellular energy their amino groups are removed and liberated as what?
in the liver urea is combined with carbon dioxide to form
Why is the amine group of an amino acid toxic to cells?
The amino group of an amino acid contains the elements Nitrogen and Hydrogen. By itself, it is not toxic to cells. But after deamination where the amino group is removed from the amino acid, the amino group is then converted into ammonia. Ammonia is toxic to cells, and also contains Nitrogen and Hydrogen, but it has a different chemical formula from the amino group.
What Portion of DNA which carries the genetic code for the formation of a particular protein by specifying its amino acids sequence?
Gene
