1
what is the four classes of biological macromolecules
proteins, lipids, carbohydrates, nucleic acids,
2
A very large molecule, such as a polymer or protein, consisting of many smaller structural units linked together….by a process called DEHYDRATION SYNTHESIS
Macromolecule
3
biological macro-molecule are made up of a small number of elements
Carbon, Hydrogen, Oxygen, (Nitrogen, Phosphorus)
4
what are the three out of four biomolecules can be found on food
fats, carbs, protein
5
what are the types of Nucleic Acids
DNA (DeoxyriboNucleic Acid) RNA (RiboNucleic Acid)
6
Almost all of the molecules that make up your body are ______, chains of subunits.
polymers
7
Each type of macromolecule is a polymer composed of a different type of subunit called a ________
monomer
8
subunits of the macromolecules are covalently-bonded. The covalent bonds between the subunits are always formed by a type of reaction called _____________ (making something while losing water).
Dehydration synthesis
9
what happens during dehydration synthesis?
a water molecule is lost, electrons are rearranged, and a new bond is formed between the subunits.
10
what are the organic molecules?
Carbon atoms are present ,Carbon forms four covalent bonds with other atoms, This allows for a wide variety of organic molecules. Organic molecules are found in both living and non-living thing
11
what are the non organic molecules
Hydrocarbons: The simplest organic compound Contain only carbon and hydrogen Carbon atoms bond easily to each other forming numerous types of hydrocarbons molecules
12
Carbohydrates, What do they do
They are the main source for the body to gain energy. They are our fuel! CARBS= ENERGY and CELL WALLS
13
Carbohydrates, where are they found ?
In plant foods- in the cell walls of plants --- in fruits, vegetables, peas, beans, SUGAR comes from a plant and so does FLOUR! (pasta, potatoes, bread, candy, cookies)
14
2 TYPES OF CARBOHYDRATES
Simple, complex
15
Simple Sugars are carbohydrates made up of 1 or 2 monomers. They also taste sweet. example of simple sugar
cookies,cakes, candies
16
Complex Cabohydrates are polymers made up of many monomers. Most also taste starchy. Examples of complex carbs?
starch, potatoes, pastas
17
Carbohydrates are chains (polymers) made of monomers. The most common monomer of carbohydrates is…
glucose
18
Each carbohydrate is made up of…
Carbon, Hydrogen, and Oxygen
19
Lipids, What do they do?
They are a great source of STORED ENERGY so we have it in the future. They INSULATE the body to maintain normal body temperature and they CUSHION the internal organs for protection. They produce hormones for the body called STERIODS.
20
Interesting info about lipids
Fruits produce a waxy coating to keep from drying out. The cells in a tulip make a wax which helps coat the leaves. Ear wax traps dust, sand, and other foreign particles from going deeper into the ear and causing damage.
21
many different types of steroids. They are all lipids. Their functions vary. Some common steroids are:
SEX STEROIDS , ANABOLIC STERIODS CHOLESTEROL,Like testosterone and estrogen and muscle
22
LIPIDS,WHERE ARE THEY FOUND?
In plants --In animals- in adipose tissue, connective tissue, in animals -- Lipids make up the cell membrane of all cells.
23
Examples of lipids
oil, butter magarine
24
lipids made up of...Lipids are chains (polymers) made of monomers. Lipids are made of glycerol and fatty acids
glycerides
