What else can I help you with?
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.
What amino acid has a methyl group as its R group?
Alanine is the amino acid with a methyl group as its R group.
What are the parts of an amino acid molecule?
An amino acid molecule consists of an amino group (NH2), a carboxyl group (COOH), a central carbon atom (α-carbon), a hydrogen atom, and a side chain (R group) that varies among different amino acids.
Which of the following is not attached to the central carbon atom in an amino acid?
In an amino acid, the central carbon atom is attached to an amino group, a carboxyl group, a hydrogen atom, and an R group (side chain). Therefore, the central carbon atom is not attached to a phosphate group in an amino acid.
Which amino acid has no free alpha amino group?
Proline is the amino acid that does not have a free alpha amino group in its side chain. This is because proline's side chain cyclizes back to the amino group, forming a unique structure that lacks a free alpha amino group.
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.
Why is the R group in amino acids?
The R group in an amino acid are what make that amino acid unique.
What funtional group of aspirin causes it to irritate the stomach?
Ester, a carboxylic acid.
Why is the R group in amino acids important?
The R group in an amino acid are what make that amino acid unique.
What is the functional group of Glutamic acid?
The functional group of Glutamic acid is a carboxylic acid group (-COOH) and an amino group (-NH2), which are key components of amino acids.
What is the chemical attraction between the acid group of one amino acid and the amino group of another amino acid can form?
the carboxylic acid group of a amino acid will give of an OH molecule while the amino group of the other will give of an H atom to form ah H2O molecule and while the carboxylic group or the C terminal connect to the amino group of the other giving you CONH as the peptide bond.
Is there any amino acid having secondary amino group in its structure?
The amino acid proline is the only amino acid that has a secondary amine functional group. This is because proline is a cyclic amino acid that links the 3-carbon R-group back to the amine group, resulting in a secondary amine.
Is formic acid a simple amino acid?
No, formic acid is not a simple amino acid. It is a simple carboxylic acid with the chemical formula HCOOH. Amino acids are organic compounds containing an amino group (-NH2) and a carboxyl group (-COOH).
Why is glutamic acid an acidic amino acid and lysine a basic amino acid?
Glutamic acid has a carboxylic acid (COO-) group on the gamma carbon of the amino acid. The carboxylic acid group carries a negative charge and is considered acidic. Lysine has a amino group (NH3+) on the zeta carbon of the amino acid. The positively charged group on the terminal carbon atom makes it an basic amino acid.
What are the two groups of amino acid?
The functional groups of an amino acid are the amino group (-NH2) and the carboxyl group (-COOH).
In transamination the amino group of an amino acid is?
transferred to a keto acid
True or false An amino acid contains either an amino group or a carboxylic acid group?
the answer is true
