Question

1. examine the amino acids shown in the diagram.

a. circle the amine group on amino acid 1.
b. draw a triangle around the carboxylic acid (carboxyl) group on amino acid 2.

1. in the diagram above, two amino acids are covalently bonded together through a condensation reaction to make a dipeptide. a peptide bond is a

Explanation:

1a. The amine group (-NH₂) in Amino Acid 1 is the -NH₂ attached to the central carbon. Circle it.
1b. The carboxylic - acid (carboxyl) group (-COOH) in Amino Acid 2 is the -COOH at the end of the molecule. Draw a triangle around it.

1. In a condensation reaction between two amino - acids, the amine group of one reacts with the carboxyl group of the other, releasing a water molecule and forming a peptide bond (-CO - NH -) to create a dipeptide.

Answer:

1a. Circle the -NH₂ group in Amino Acid 1.
1b. Draw a triangle around the -COOH group in Amino Acid 2.

1. A peptide bond is formed between the amine group of one amino - acid and the carboxyl group of another through a condensation reaction, releasing water to form a dipeptide.
