Flashcards in Bio Test #4 Deck (31):
1

Organic Compounds

Compounds that contain carbon found in living organisms

2

What are inorganic compounds that contain carbon, that is found in living organisms?

CO2 (carbon dioxide), CO3 (carbonate),& HCO3 (bio carbonate)

3

What are the 3 main organic compounds?

Carbohydrates
Proteins
Lipids

4

What are characteristics of organic compounds?

Large & seem very complex, but in reality they are built using small & relatively simple monomers

5

Monomers

Subunits

6

Polymers

Monomers joined together

7

What are monomers for carbohydrates?

Glucose
Ribose
Fructose

8

How many carbon compounds does glucose contain?

C6H12O6; 6 carbon compounds

9

How many carbon compounds does ribose contain?

C5H10O5; 5 carbon compound

10

What are functions of carbohydrates?

Quick form of energy, transport energy, stores energy

11

Saccharides

Another word carbohydrates

12

What are monomers of protein?

Amino acids

13

Protein

Amino acids joined together

14

Peptide

Another word for amino acids

15

How are amino acids joined together?

By a condensation reaction

16

Peptide bond

A covalent bond between two amino acids

17

What are functions of protein?

They control the rate of reaction, proteins are a part of bones & muscles, transport things in and out of cells, help fight diseases

18

What are monomers of lipids?

Glycerol & fatty acid

19

Glycerides

Another word for lipids

20

Monoglyceride

1 fatty acid chain linked to glycerol

21

Diglyceride

2 fatty acid chains added to the glycerol

22

Triglyceride

3 fatty acid chains are added to the glycerol

23

What can lipids be?

Saturated or unsaturated

24

Saturated

With hydrogen

25

Unsaturated

Fatty acid train loses some hydrogen & forms double bonds between carbon, there can be more than one double bond

26

What are the functions of lipids?

Long term energy storage, water proof covering on leaves (wax), heat insulation, buoyancy, part of cell membrane (phospholipid bilayer)

27

Heat insulation

Fat under skin reduced heat loss

28

Buoyancy

Fat is less dense than water & it helps them float

29

How are carbs different than lipids in energy storage?

Easily digested (energy can be released more quickly same); soluble in water, so they are easier to transport; short term energy

30

How are lipids different than carbs in energy storage?

Cannot be digested as easily but they contain more energy per gram, so storage of lipids is lighter than carbohydrates for the amount of energy; in soluble in water so they do not cause problem w/ osmosis in cells; long term energy

31

Indicator

Chemical substances that react w/ specific compounds (they change color when they react w/ a specific compound (the color change indicates presence of that compound))
