Amylopectin

all glucose

Starch = Amylose + Amylopectin (How plants store glucose)

Amylose

all glucose

Amylopectin – how plants store glucose

Glycogen – how animals store glucose (same structure but more branch points Amylopectin – branch every 12-20 units

Glycogen – branch every 8-10 units)

The 20-mile mark - when you run out of glycogen :

Cellulose – glucose polimer with 1,4-glycoside bonds

Amylose

Cellulose: the most widely distributed plant skeletal sugar ½ the cell wall material of wood

almost 100% of cotton

glucose

2 x pyruvate

+ energy

Glycolysis: the breakdown of glucose to pyruvate

Krebs cycle (more energy)
