Interpretation:
The names, three-letter abbreviations and one-letter abbreviations for the given structure of amino acids are needed to be determined.
Concept introduction:
Amino acids are organic compounds containing amino as well as a carboxylic group. The general molecular formula of an amino acid is as follows:
Here, R refers to different groups for different amino acids. If there is more than one amino group present in amino acid, it is considered as basic amino acid and if there is more than one carboxylic group present, then it is considered as an acidic amino acid.
Answer to Problem 1P
A: Proline, the three-letter abbreviation is Pro and a one-letter abbreviation is P.
B: Tyrosine, the three-letter abbreviation is Tyr and a one-letter abbreviation is Y.
C: Leucine, the three-letter abbreviation is Leu and a one-letter abbreviation is L.
D: Lysine, the three-letter abbreviation is Lys and a one-letter abbreviation is K.
Explanation of Solution
The given structure of amino acids (A-D) are:
The amino acid in structure A is proline. It is one of the a-amino acids that is used by living organisms as the building blocks of the proteins. Its three-letter abbreviation is Pro, and one letter abbreviation is P.
Structure B represents a non-essential amino acid, tyrosine. In animals, it is synthesized from phenylalanine. It is also the precursor of epinephrine, thyroid hormones and melanin. Its three-letter abbreviation is Tyr, and one letter abbreviation is Y.
The structure C represents the amino acid Leucine which is obtained from the hydrolysis of most common proteins. It was discovered in 1819in muscle fiber and wool. Its three-letter abbreviation is Leu and the one-letter abbreviation is L.
The structure D represents the amino acid Lysine which is an essential amino acid for the nutrition of humans. Its three-letter abbreviation is Lys, and one letter abbreviation is K.
A: Proline, the three-letter abbreviation is Pro and a one-letter abbreviation is P.
B: Tyrosine, the three-letter abbreviation is Tyr and a one-letter abbreviation is Y.
C: Leucine, the three-letter abbreviation is Leu and a one-letter abbreviation is L.
D: Lysine, the three-letter abbreviation is Lys and a one-letter abbreviation is K.
