Document Summary
Main function of pancreas: secretes hormones: insulin (beta cells secrete insulin, signal from pancreas) Type 1 diabetes: pancreas doesn"t secrete enough/doesn"t secrete insulin (simple inflammatory marker turns into complete destruction for pancreas)-->beta cells destroyed, can"t secrete insulin at all. Type 2 diabetes: pancreas secretes too much insulin (ate too much saturated fat and sugar, so pancreas secretes a ton of insulin)-->insulin resistant/insensitive. Glucose: main energy source, metabolized in presence of oxygen. Cellular respiration: byproducts: carbon dioxide, water, atp (energy) Ketogenesis: what we do when we haven"t eaten; plan b for energy. Added sugar: way higher correlation with heart disease than fats. Lipid: any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents--include many natural oils, waxes and steroids. Triglyceride (tag): ester derived from glycerol and three fatty acids (tri+glyceride)
