Control of Fatty Acid Synthesis vs. Oxidation - When Insulin is HIGH --> fatty acid synthesis occurs When Glucagon is HIGH --> lipolysis, fatty acid B-oxidation, ketogenesis occur **These never happen at the same time! Lipolysis - Process of releasing free fatty acids from triacylglycerols stored in the adipose IN THE FASTED STATE Steps of lipolysis - 1) Hormone Sensitive Lipase: activated by glucagon and epinephrine TAGs are hydrolyzed into FFAs and glycerol (inhibite...
