I understand that you have been searching for information on invariant amino acids and have only found journal articles. Allow me to explain what invariant amino acids are and guide you on where to find more accessible information.

Invariant amino acids, also known as conserved amino acids, refer to amino acid residues that remain unchanged or minimally altered across different species or within a specific protein family. These residues are crucial for maintaining the structure, function, or stability of a protein.

To find more information on invariant amino acids, you can try the following steps:

1. Utilize a more general search query: Instead of searching for "invariant amino acids," try searching for "conserved amino acids" or "amino acid conservation." This broader term may provide more accessible information.

2. Use educational websites: Look for educational websites or resources that explain protein structure and the role of amino acids. Some reputable sources include Khan Academy, BioNinja, or Protein Data Bank (PDB) websites.

3. Look for textbooks or online courses: Search for textbooks or online courses related to biochemistry, molecular biology, or protein structure. These resources usually provide detailed explanations on amino acids and protein conservation.

4. Consult online forums or communities: Participate in online communities specific to biology or biochemistry. You can ask questions or request accessible explanations on platforms like Reddit, Quora, or Biology Stack Exchange.

Remember, if you're not finding easy-to-understand information, it may be helpful to utilize different search terms or explore different types of resources beyond scholarly articles.
