Identifying the C-Terminal Amino Acid in a Peptide Chain

The question of which is the C-terminal amino acid in the peptide ala-gln-arg-ser-his is fundamental to understanding peptide structure and function. In any peptide chain, amino acids are linked together by peptide bonds, forming a linear sequence. This sequence has distinct ends: the N-terminus, which has a free amino group, and the C-terminus, which has a free carboxyl group.Solved Which is the C-terminal amino acid in the peptide The C-terminal amino acid is the one that terminates the chain at the carboxyl endWhich is the C-terminal amino acid in the peptide ALA-GLN-ARG-SER- HIS? a ... The amino terminal amino acid is: a. Arg b. Cys c. Gln d. Met e. None of ....

For the specific peptide sequence Ala-Gln-Arg-Ser-His, the amino acids are listed from the N-terminus to the C-terminus. Therefore, the amino acid at the very end of this sequence, possessing the free carboxyl group, is Histidine (His). This means that His is the C-terminal amino acid in the peptide Ala-Gln-Arg-Ser-His.Characterization of the C-terminal Flanking Peptide ...

The order in which these amino acids are linked is crucial for their biological activity.Primary structure of single-chain pro-urokinase. Each amino acid has a central alpha-carbon atom bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a unique side chain (R-group). When amino acids join to form a peptide, the carboxyl group of one amino acid reacts with the amino group of another, releasing a molecule of water and forming a peptide bond (-CO-NH-).2018年12月9日—Which is the C-terminal amino acid in the peptide ALA-GLN-ARG-SER-HIS? a.

The end of the chain with the free amino group is called the N-terminus (amino-terminus), and the end with the free carboxyl group is called the C-terminus (carboxyl-terminus). The naming convention for peptides typically starts with the N-terminal amino acid and proceeds to the C-terminal amino acidProteins, Peptides, and Amino Acids.

In the peptide Ala-Gln-Arg-Ser-His:

* Ala (Alanine) is the first amino acid, at the N-terminus.

* Gln (Glutamine) is the second.

* Arg (Arginine) is the third.

* Ser (Serine) is the fourth.

* His (Histidine) is the fifth and final amino acid, at the C-terminus.

Significance of C-Terminal Amino Acids

The C-terminal amino acid plays a significant role in several biological processes. For instance, it can be a target for enzymatic modification or degradation. Some enzymes specifically cleave amino acids from the C-terminus of a peptide or protein. The free carboxyl group at the C-terminus also contributes to the overall charge and chemical properties of the peptide, which can influence its solubility and interactions with other molecules.

Furthermore, in certain signaling pathways or protein processing events, the identity of the C-terminal residue can be critical for determining how a protein is recognized, modified, or targeted within a cell.PeptideCutter - Cleavage specificities of selected enzymes ... For example, some peptides are synthesized with a C-terminal amide instead of a free carboxyl group, a modification that can alter their stability and biological activity.
