Document Summary
All cells have fatty acids within, the plasma has more during fasting. Fasting need a source of energy, if glucose is not available it comes from the fat reserves and goes into where gluconeogenesis can form it into energy. Beta-oxidation into two carbon groups which frees energy. Function inner and outer membrane components. Glucose transporter and/or sodium transporters are proteins that exist on the cell membrane, they can be lipoproteins. Prostaglandins small hormones important for regulation especially in smooth muscle or skeletal muscle contraction. Can help control bp arterial walls. Can move around they are not static * (fluid mosaic model) Palmitoleic acid 16 carbons and one unsaturated group. Linoleic and alpha linolenic acid are essential fatty acids. Cannot be synthesized by the body and are acquired through the diet. Glycerol in glycolytic pathway, triacylglycerol when it is being targeted is broken into fatty acids and fatty acid coa.
