1 Chemicals of Life

2 4 classes of biological molecules:
_________________________

3 Chemicals of Life Living cell components:
assembling into _______________ forming _______________ storing/relaying _______________ Required for a variety of cellular processes: ______________________________

4 Carbohydrates Accessible _______________ to fuel _______________
Provides _______________ inside plant cell walls Simple Sugars _______________ Complex Sugars

5 Disaccharide Monosaccharide Complex sugars Simple sugars:
_______________ sugar molecules bonded together Ex’s sucrose (table sugar), maltose, lactose Simple sugars: _______________ sugar molecule Fuel for cellular work Ex’s: glucose, fructose, galactose, ribose

6 Polysaccharide __________________sugar molecules together that create ______________________________ Short term ____________________ of sugar Provide structural support for ___________________ Ex’s: ___________________________________________

7 Lipids Excellent _________________________________compound
Used as protection and in communication Carry many important _____________________ *base components of _____________________ Serve as ___________________ to the skin Protects _____________________ of body Insoluble in water

8 Groups of Lipids _______________________
Made up of a glycerol and fatty acids Fatty acid chains can be saturated or unsaturated

9 Unsaturated Fats ____________Liquid at room temperature (plant oils)
No C=C double bonds Disadv: harder for body to break down Adv: permit cooking at higher temp Unsaturated Fats ____________Liquid at room temperature (plant oils) One or more C=C double bond Trans fats : double bonds easier to digest

10 Phospholipids Phospholipids make up the _______________________
Composed of two parts: __________________+ _________________ (Hydrophillic: water-liking) 2 _______________________ (Hydrophobic: water-hating) Fatty acid chains can be saturated or unsaturated

12 Proteins Large molecules made from _______________________________________ (building blocks) Combine to form ______________________ Different kinds of proteins support different types of functions

13 Protein Functions: ______________________ are proteins that act as biological catalysts, regulate the rate that cellular reactions occur. _______________________ proteins provide internal and external support to protect/maintain cell shape like hair, skin, nails, feathers

14 Functions continued: _________________________ proteins provide basis for cellular and whole organism movement (muscular movement) _________________________proteins such as antibodies help body defend itself against disease agents _________________________organisms store proteins as a source of amino acids for later use, usually in growth and development. Found in egg whites and plant seeds.

15 Nucleic Acids DNA (__________________nucleic acid)
The genetic information that programs ________________________. Found in all living organisms Transmits genetic information from ______________________________ Stays within the nucleus * RNA (_________________nucleic acid ) Single stranded nucleic acid Used to translate the information from ________ into ______________

16 Nucleotides Free nucleotides combine together to form nucleic acids
___________________________ - DNA: ___________________ sugar - RNA: ___________________ sugar DNA Bases:___________(A), __________ (T) ___________ (C), __________(G) RNA Bases: Instead of ______________ has _____________
