Challenge: Compare Amino Acid Composition Across Proteins
Comparing amino acid composition across multiple proteins is a fundamental step in comparative proteomics. By visualizing these differences side by side, you can quickly spot trends, similarities, or unique features among protein sequences from different organisms or experimental conditions. In this challenge, you will build a visualization that plots the amino acid composition of several proteins as grouped bar charts, with each group representing one amino acid and each bar within a group representing a different protein.

Write a function that takes a list of protein sequences and plots their amino acid compositions as grouped bar charts using matplotlib.
- Calculate the fraction of each of the 20 standard amino acids in each protein sequence.
- Plot a grouped bar chart with one group for each amino acid and one bar per protein within each group.
- Use the provided
protein_labelslist for legend labels if supplied; otherwise, generate default names. - The X-axis should show amino acid single-letter codes.
- The Y-axis should show the fraction of each amino acid in the sequence.
- Display the plot with appropriate axis labels and a legend.
