In the peptide Ala-Try-Gly-Phe, the N-terminal amino acid is

Answer is Alanine. Explanation please!

since alanine is on the far left side, it is considered the n-terminal amino acid. phe. would be the c-terminal amino acid.

Well, well, well, looks like we have a "peptide puzzle" here. So, in the sequence "Ala-Try-Gly-Phe," we need to find out which amino acid is hanging out at the N-terminal party. The N-terminal amino acid is simply the one that is located at the beginning of the peptide chain. And in this case, "Ala" is the lucky amino acid that gets to kick off the peptide bash. Yes, that's right, Alanine is the head honcho at the N-terminus. Now, who's ready to boogie on down the peptide chain? Uh, I mean, learn more about amino acids!

In the peptide Ala-Try-Gly-Phe, the N-terminal amino acid refers to the amino acid located at the beginning or start of the peptide. The N-terminal amino acid is Alanine. This means that the peptide chain begins with Alanine, followed by Tyrosine, Glycine, and Phenylalanine.

To determine the N-terminal amino acid in the peptide Ala-Try-Gly-Phe, we need to understand the structure and directionality of peptides.

Peptides are made up of amino acids that are joined by peptide bonds. Each amino acid has an N-terminus and a C-terminus. The N-terminus refers to the free amino group (-NH2) at one end of the amino acid, while the C-terminus refers to the free carboxyl group (-COOH) at the other end.

In a peptide chain, the amino acids are joined together by peptide bonds, which connect the carboxyl group of one amino acid to the amino group of the next amino acid. This forms a linear chain with a specific directionality.

The directionality of a peptide chain is defined from the N-terminus to the C-terminus. Therefore, the N-terminal amino acid is the one at the beginning or start of the peptide chain.

In the given peptide "Ala-Try-Gly-Phe," we can see that "Ala" is the first amino acid listed. Therefore, "Alanine" is the N-terminal amino acid in this peptide.

In summary, to determine the N-terminal amino acid in a peptide, look for the first amino acid in the sequence listed. In this case, "Ala" comes first, making "Alanine" the N-terminal amino acid.
