1

What is oxygen's partial charge in water and why

It has a partial negative charge bc of its greater electronegativity

2

Alkalinity (basic)

Measure of hydroxide ion concentration

3

Organic Compounds

Molecules that are carbon and hydrogen based

4

Why can carbon make complex structures?

Bc it can bond four times due to its high electronegativity

5

Four Organic Compounds

Carbs, lipids, proteins, nucleic acids

6

Which of the four organic compounds are macromolecules?

Carbs, proteins, nucleic acids

7

Carbohydrate Isomer

Same molecular formula but different structural formula

8

Monosaccharides types

Glucose, fructose, and galactose

9

Monomer

Basic building block that can be a repeating unit

10

Disaccharide

Two simple sugars bonded

11

Glucose+glucose=

Maltose

12

Glucose+fructose=

Sucrose

13

Glucose+galactose=

Lactose

14

What ratio must there be between hydrogen and oxygen in order for it to be a sugar

2:1

15

Polysaccharides

Macromolecules

16

Macromolecules

A molecule made of repeating units

17

Examples of polysaccharides

Starch
Glycogen
Cellulose
Chitin

18

Where is starch stored?

Plants

19

Where is cellulose stored?

Cell wall of plants

20

Where is glycogen stored?

Animals

21

Where is chitin stored?

Exoskeleton of some animals

22

What do carbs provide?

Structure, quick energy when bonds break, protection

23

What do lipids provide?

Store energy, cushion, insulation, regulates what goes in and out of cell

24

What are phospholipids made up of? What is it?

Glycerol, phosphate group, two fatty acids . It's amphipathic

25

Amphipathic

A molecule that has both hydrophobic and phyilic parts

26

Saturated vs. unsaturated fat

Sat is single bonded, can be compressed
Unsat is double bonded so it's bent

27

Glycosidic bonds

Bonds that bond sugar monosaccharides

28

Ester bonds

Bonds that bond lipids

29

Waxes

Ester bonds with long carbon chains

30

Enzymes

Proteins that act as catalysts to a reaction
