Flashcards in Macromolecules Deck (60):
1

Macromolecules

Cells and their organelles are made up of smaller building blocks

2

Types of macromolecules

Lipids
Proteins
Carbs
Nucleic acids

3

Each subunit of a macromolecule is

Monomer

4

Polymers make up ..

Monomers

5

Lipid structure

Monomer : fatty acid
Polymer : lipids

6

Types of lipids

Triglycerides
Steroids
Phospholipids

7

Triglycerides

Food sources of fat

8

Steroids

Hormones & cholesterol

9

What causes Fatty acids to be saturated and unsaturated ?

If it's solid = saturated
If liquid or room temp = unsaturated

10

What does it mean that lipids are non polar and how does this affect their relative w water ?

Doesn't need to be mix w water

11

Saturated can ...

Can't Take anymore

12

Unsaturated can..

Take more

13

Polar head & non polar tail regions is

Lipids

14

Lipids function

Make up membrane , providing cell structure

Long term energy storage

15

Lipid food source

Fatty foods
Meat , oils , eggs

16

Proteins structure

Made up of monomer : amino acids ( 20 different kinds )

Polymer = protein ( polypeptides )

17

Proteins structure

The shape of a protein determines its function

18

Levels of protein structure

Primary structure
Secondary structure
Tertiary structure
Quaternary structure

19

Protein function

Build and repair muscle and tissues

20

Enzymes

Proteins that speed up chemical reactions

21

Proteins food source

Meat , fish , buts , milk , eggs , gains , soy

22

Relationship between glucose , fructose , & galactose

They are isomers of one another
They have the same chemical formula , but different in how the elements are bonded to each other

23

Unsaturated

A double bond between atleast two carbons in the fatty acid

24

Saturated

Carbons only have a single hydrogen bonded to each

25

You need quick boost of energy ?

Monosaccharide

26

You want to grow strong nails ?

Animal & plant structures

Protein

38

Forms the cell membrane of all cells

Lipids

39

Speeds up chemical reactions by lowering activation energy

Protein

40

One sugar

Carb

41

Monomer of proteins

Protein - amino acids

42

Long term energy storage for plants

Carb

47

What percentage of your food should be from carbs ?

60%

48

Carb supplies

Energy

49

Carbs play a role in

Digestive
Metabolism
Oxidation

50

Unused portion of carb is stored in

The liver or tissues as fat

51

Carbs mainly come from

Plant sources

52

Simple carb

Quick energy sources , don't usually supply nutrients or fiber

53

Glucose

The major kind of simple sugar . Basic source of energy for all living things

54

Sucrose

Commonly known as table sugar , beet , or cans . Occurs in fruits or veggies

55

Fructose

Known as fruit sugar . Most plans contain this sugar especially fruits and saps

56

Glucose

Sometimes known as blood sugar and nearly all plant foods contain this sugar

57

Maltose

Known as malt sugar , is found in grains

58

Lactose

Known as milk sugar , is found in the principal carb in milk

59

Starch

The body breaks down simple sugars
Break down sugar & starchs into glucose

60
