• A) Skin cells show lower levels of 18:0 relative to 18:1 AND higher levels of 16:0 relative to 18:0.
• B) Skin cells show higher levels of 20:0 relative to 18:0 AND higher levels of 18:2 relative to 18:0.
• C) Skin cells show lower levels of 20:0 relative to 18:0 AND lower levels of 18:0 relative to 18:2.
• D) Skin cells show higher levels of 18:2 relative to 18:0 AND lower levels of 16:0 relative to 18:0.
