Textbook Question
Give the name for the amino acid represented by each of the following abbreviations:
d. G
Verified step by step guidance1
Step 1: Understand that the question is asking for the name of the amino acid represented by the single-letter abbreviation 'G'.
Step 2: Recall that amino acids are often represented by either a three-letter abbreviation or a single-letter abbreviation. For example, Glycine is represented as 'Gly' (three-letter) or 'G' (single-letter).
Step 3: Identify the amino acid corresponding to the single-letter abbreviation 'G'. In this case, 'G' stands for Glycine.
Step 4: Glycine is the simplest amino acid, with the chemical formula NH₂CH₂COOH. Its side chain (R group) is a single hydrogen atom, making it nonpolar and achiral.
Step 5: Conclude that the name of the amino acid represented by the abbreviation 'G' is Glycine.
