Amino acids have both amine and carboxylic acid functional groups and are therefore both an acid and a base at the same time.
Ammine group -NH2, the basic part. Carboxilic group -COOH,the acidic part
Its false
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.
amino acid
There are two ions present in every amino acid. There is a positively charged amino group and a negatively charged carboxyl group.
Proline
The R group in an amino acid are what make that amino acid unique.
Ester, a carboxylic acid.
An amino acid always has an amino group and a carboxyl group. The amine group of one amino acid is capable of forming a peptide bond with the carboxyl group of another amino acid.
The R group in an amino acid are what make that amino acid unique.
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.
Its false
The functional groups of an amino acid are the amino group (-NH2) and the carboxyl group (-COOH).
transferred to a keto acid
The amino acids are distinguished by the R groups which determines what amino acid it is.
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.
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.
the answer is true
