Scientists think a specific part of a protein called CRT1 is probably not charged like they thought before—because if it were charged, it would mess up the protein’s shape and doesn’t really help the protein grab creatine.

Scientists studied a specific part of a protein that brings creatine into cells and found that a particular amino acid (C144) is not charged like some thought — it’s neutral, which makes the protein more stable and still works fine for grabbing creatine. This matches what the claim said.
