Functions of trilgycerides (5)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Blubber for bouyancy (fat weighs les than muscle)

Insulation

Protector of organs & shock absorber

Energy source

Water source

Why does body store triglycerides rather than carbohydrates (glucose)? (2 reasons)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Triglyceride metabolism yields (wins) more ATP than glucose

Adipose tissue (lipid sotrage) can expand exponentially whereas carbohydrate storage (liver) has finite size

Differences and similarities of diglycerides and phospolipids (number of fatty acid chains, hydrophilic region, hydrophobic region)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Diglycerides: two fatty acid chains, no hydrophilic region, hydrophilic region

Phospholipids: two fatty acid chains, hydrophilic and hydrophobic regions

Phospholipids (twi things that make them useful)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Unsaturated fatty acid chain (kink) makes hydrophobic region flexible

Hydrophilic head keeps the membrane together and protects them from bigger and hydrophobic molecules

Sterols (structure 1, properties 3)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Tetra-ring structure

Grouped in lipids (same properties)

Non soluble in polar solvents (water)

Soluble in non polar (organic) solvents (ether)

Cholesterol (function (3), properties (2) -> (1))

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Hormone synthesis, vitamin d synthesis, structural support in membranes

Extremely hydrophobic and insoluble in polar solvents

Packed into apolipoprotein (lipid,cholesterol,protein bundle)

What happens if you have too much cholesterol? (3)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Heart disease

Atherosclerosis

Inflexible membranes

HDL (definition, function (2), how much cholesterol do they contain?)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Apolipoprotein (lipids,cholesterol,protein) -> High density of cholesterol

Transportation of fat (cholesterol, phospholipids, triglycerides) & cholesterol from cells to liver for excretion or reuse

LDL (definition, function, how much cholesterol do they contain?)

Commandes clavier:

= tourner,

= avant/arrière,

= faire défiler

Apoliopprotein -> Low density of cholesterol

Deliver cholesterol to cells (used witihn membrane and synthesis of steroid hormones)
