Carbohydrates:
(CH2O) Main energy source of humans

Classification

Monosaccharide:
"Basic units of carbohydrates"

Glucose/Dextrose:
"found in the body as a result of CHO digestion"

Role

Energy source for cellular metabolism

Forms glycogen as a form of storage in the liver and muscles

Transforms into triaglycerol for later use

Fructose:
"found in high concentration in fruits and honey and can enter the blood stream rapidly

Galactose:
"Must be manufactured, binds with glucose to form lactose"

Olisaccharides

Polysaccharides

Roles

Provide Energy at rest and during PA

Preserve structural and functional integrity of the organism

Gluconeogenesis:
"body's process of creating new sugar from leftover carbon from other compounds"
