And that means, because the bonds holding the phospholipids and proteins together are weak, that means they will not remain stationary in place, but rather, they will be found in a constant sideways motion. So our phospholipids and proteins will be in a constant lateral state of motion. So they will be moving sideways, as shown in the following diagram. So, for example, this fossil lipid could move here, could move here. The protein could also move into different locations. Now, one important point that I must point out is the following.
