Tóm tắt

Lipid sulphoquinovosyldiacylglycerol là một lipid mang điện tích âm, tồn tại trong màng tilacoide. Có giả thuyết cho rằng một tỷ lệ lớn lipid acid này không tham gia vào ma trận lipid chủ yếu mà gắn chặt với các phức hợp protein, nơi mà nó gắn kết chặt chẽ và tham gia vào việc tối ưu hóa hoạt động xúc tác, hoặc duy trì các phức hợp ở trạng thái cấu hình chức năng. Bằng chứng thí nghiệm cho giả thuyết này đang xuất hiện từ các nghiên cứu với hệ thống quang hợp 2 và các phức hợp yếu tố liên kết.
