2 Carbohydrates I.Main function in cell: A._____________________; B.main component of ____________ II.Main dietary sources: A.Foods high in _________________ B.____________________ C.___________ and other ____________ vegetables

3 Carbohydrates I.Common elements A.Made of: Carbon, Hydrogen, Oxygen (CHO) in a ______________________ II.Monomer A.__________________________ 1.Mono = one & saccaride = sugar B.Examples: ___________ (shown), fructose, galactose

4 Carbohydrates I. Disaccharide: ___________________ A.Chemical Formula: C 12 H 22 O 11 B.Example: 1.________ – _________ + _________ = table sugar 2.Maltose – glucose + glucose = malt 3.____________ – glucose + galactose = milk sugar

5 Carbohydrates I. __________________: many sugar units; known as a complex carbohydrate, or ___________________ A.Examples: 1._________________ (bread, potatoes) – stored in plants; 100s of glucose 2._______________________(beef muscle) – _________________muscle of animals; maintains blood and sugar levels and generates ATP for muscle contraction 3.________________(lettuce, corn) – ____________________________; 4. gives structural support to plants

6 Proteins I.Main function in cell: A.________________________ B.Drives chemical reactions (___________) II.Main dietary sources: A.Seafood and ___________ B.______ and other dairy products C._____________ and beans

7 Proteins (Polypeptides) I.Common elements: A.Made of: ________________________ (CHON) II.Monomer A._________________ 1.Amino acids have a central carbon with 4 things boded to it: 2.The __________________________ _ __________ that gives each amino acid its properties.

8 I.Amino acids (__________________) bonded together by ________________________. II._______________________________________________ (known as a protein backbone) aa1aa2aa3aa4aa5aa6 Peptide Bonds Amino Acids (aa) Proteins (Polypeptides)
