Lipids Flashcards
serve as insulating materials against atmospheric heat and cold and protect internal organs.
subcutaneous lipids
act as electrical insulators, allowing rapid propagation of depolarization waves along myelinated nerves.
Nonpolar lipids
responsible for membrane integrity and regulation of membrane permeability.
Lipids in biomembranes
actively participate in electron transport chain.
Lipids present in inner mitochondrial membrane
important cellular constituents, occurring both in the cell membrane and in the mitochondria, and serving also as the means of transporting lipids in the blood.
Combinations of lipid and protein (lipoproteins)
Carbohydrate vs. Lipid
Short-term energy storage
Carbohydrate (glycogen)
Carbohydrate vs. Lipid
Long-term energy storage
Lipid (triglyceride)
Carbohydrate vs. Lipid
More effect on osmotic pressure
Carbohydrate (glycogen)
Carbohydrate vs. Lipid
Less effect on osmotic pressure
Lipid (triglyceride)
Carbohydrate vs. Lipid
More readily digested - used for aerobic or anaerobic respiration
Carbohydrate (glycogen)
Carbohydrate vs. Lipid
Less easily digested - can only be used for aerobic respiration
Lipid
Carbohydrate vs. Lipid
Stores half as much ATP per gram (~1760kJ per 100g)
Carbohydrate
Carbohydrate vs. Lipid
Stores twice as much ATP per gram (~4000kJ per 100g)
Lipid
Carbohydrate vs. Lipid
Water soluble as monomers/dimers - easier to transport
Carbohydrate
Carbohydrate vs. Lipid
Not water soluble (hydrophobic) - more difficult to transport
Lipid
Lipids serve as metabolic regulators of
steroid hormones and prostaglandins.
