True or False A peptide bond joins the amino group of one amino acid to the amino group of another amino acid?
False. A peptide bond joins the carboxyl group of one amino acid to the amino group of another amino acid.
Which term describes an amino acid normally found in the blood?
The term "free amino acid" describes an amino acid that is normally found in the blood.
Where does deamination occur in the body?
The process of deamination removes the amino group from an amino acid. The amino part of the amino acid is converted into urea carried by the blood into the kidneys and removed as urine. In human body deamination takes place primarily in the liver, however, glutamate is also deaminated in the kidneys.
What type of bond forms between the new amino acid and the previous amino acid on the chain?
A peptide bond forms between the new amino acid and the previous amino acid on the chain during protein synthesis. This bond is formed through a dehydration reaction, where the carboxyl group of one amino acid reacts with the amino group of the other amino acid, releasing a molecule of water in the process.
How many Dalton in an amino acid?
An amino acid typically ranges from around 100 to 200 Daltons, depending on the specific amino acid and its side chains.
What is cystinuria?
Cystinuria is an inborn error of amino acid transport that results in the defective absorption by the kidneys of the amino acid called cystine. The name means "cystine in the urine."
If the Tm for a particular amino acid is 120 mg 100 ml and the concentration of that amino acid in the blood is 230 mg 100 ml the amino acid?
If the concentration of the amino acid in the blood is higher than its Tm value, it suggests that the amino acid is being filtered and excreted by the kidneys as it has exceeded the renal threshold. This could indicate a potential problem with reabsorption in the kidneys.
In the metabolism of amino acids for energy what is the fate of the amino group?
During amino acid metabolism for energy, the amino group is removed from the amino acid through deamination, forming ammonia. The ammonia is then converted into urea in the liver and excreted in the urine, while the remaining carbon skeleton of the amino acid can be further broken down to generate energy through pathways like the citric acid cycle.

What amino acid is technically not an amino acid?
Tryptophan is technically not an amino acid because it contains an indole ring in its structure, making it both an amino acid and an aromatic heterocycle.
What type of substance is creatine?
An amino acid that occurs in vertebrate tissues and in urine. In muscle tissue, creatine generally occurs as phosphocreatine. Creatine is excreted as CREATININE in the urine.
What is an abnormal result in amino acid screening tests?
Abnormal results in amino acid screening tests may indicate a metabolic disorder such as phenylketonuria (PKU), maple syrup urine disease, or homocystinuria. These disorders prevent the body from properly breaking down certain amino acids, leading to a buildup of toxic byproducts that can be harmful to health.
What is secondary aminoaciduria?
Secondary aminoaciduria is a condition where there are increased levels of amino acids in the urine due to other underlying factors such as a liver disorder, kidney disease, or genetic disorders affecting amino acid metabolism. It is not a primary disorder of amino acid transport or reabsorption in the kidneys. Treatment typically involves addressing the underlying cause of the increased amino acid excretion.
Why anthranilic acid is not a amino acid?
Anthranilic acid is not an amino acid because it lacks an amino group (-NH2) within its molecular structure, which is a defining feature of amino acids. Despite its name containing "acid," anthranilic acid is actually a precursor to various amino acids but is not classified as an amino acid itself.
True or False A peptide bond joins the amino group of one amino acid to the amino group of another amino acid?
False. A peptide bond joins the carboxyl group of one amino acid to the amino group of another amino acid.
How do you use amino acid in a sentence?
there is amino acid in your stomach.
What is amino acid that is in batteries?
the amino acid in the batteries is NH3+
