| CHemical break down of food to nutrients |
|
|
Term
|
Definition
Transfer of nutrients into small intestine cell
-packaging of nutrients
-release into blood or lymph
-if body is low on nutrient, body will try to absorb more |
|
|
Term
|
Definition
-Large protien molecules that facilitate specific chemical reactions
-high specificity:
Emzymes will only work on certain substances
-not altered by reactions
-names after substate: with 'ase' |

Digestion Enzymes
substate: lactose |
|
Definition
Enzyme: lactase
product: glu & gal |

|
Term
|
Definition
Epithehal-lines the outside surface and external passages - secretes, excretes, absorbs
Connective- supports and protects, holds structures together - stores fats, makes blood cells
Muscle- movement
Nervous- Transports nerve impulses |
|

Term
|
Definition
Essential for fat digestion
-not an enzyme but an emulsifer
-made by liver, stored in gallbladder
-contains alot of cholesterol
-95% reabsored in small and large instestine |

1st link in food chain
-photosynthesis: plants use 10% of suns energy to make CHO
-glucose is most abundant CHO
-Only significant animal source of CHO are milk + some milk products |
|
|
Term
|
Definition
-Energy: used in all cells
-Some cells (brain & RBC) can only use CHO
-Needed to effiently burn fat
-Spares protien from use for energy
-fiber, alternative forms of CHO provide a number of benefits |

Definition
1. Type of building block (3 main ones)
2. Size (#of building blocks 1-1000s)
3. Type of chemical bond between biulding blocks |
|
|
Term
|
Definition
Saccaride = building block
Simple CHO = 'sugars'
mono=1 di=2 tri=3
Complex CHO=starch/amylose, amylopectin
Complex CHO = fiber: different bonding then starches |
|
|
Term
|
Definition
Glucose (Glu):most abundant CHO, part of table sugar,'blood sugar'
Fructose (Fru):found in fruit and honey, part of table sugar
Galactose (Gal):part of milk sugar, generally not found in nature |
|
|
Term
|
Definition
Sucrose= Glu + Fru - table sugar
Maltose= Glu + Glu- product of amylose digestion
Lactose= Glu + Gal- milk sugar |
|
|
Term
|
Definition
Multiple glucose
-starch, amylose, amylopectin= many Glu
-Fiber= many different kinds, different chemical bonding then amylose- only found in plants
Glycogen- storage form of CHO in animals |
