Bellwork:•Essays were due yesterday•Turn in rubric with name and period on
it.•Copy and answer the following questions 1. When we added water, what process was occurring;
dehydration synthesis or hydrolysis? Describe the glue after water was added.
2. When we added borax, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after borax was added.

The glue contains a polymer called polyvinyl acetate resin.
We changed the polymer’s behaviors twice in this activity;
once when we added water and the second time when we added
borax.

Carbohydrates & Lipids
![Page 7: Bellwork: Essays were due yesterday Turn in rubric with name and period on it. Copy and answer the following questions 1.When we added water, what process.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649e975503460f94b9a7df/html5/thumbnails/7.jpg)
Objective: The objective of class today is to learn the structure and
function of carbohydrates and lipids in living systems.
![Page 8: Bellwork: Essays were due yesterday Turn in rubric with name and period on it. Copy and answer the following questions 1.When we added water, what process.](https://reader035.fdocuments.us/reader035/viewer/2022062518/56649e975503460f94b9a7df/html5/thumbnails/8.jpg)
Living things use carbohydrates as their main source of energy. Plants and some
animals also use carbohydrates for structural purposes.

The breakdown of sugars supplies immediate energy for all cell activities.

Living things store extra sugar as complex carbohydrates known as
starches.

Single sugar molecules are called monosaccharides. (simple sugars)

Three examples of monosaccharides include:
• Glucose
• Galactose
• Fructose

Large molecules made from monosaccharides are called
polysaccharides.

Carbohydrates• Rings that link
together in chains
• Ratio of carbon: hydrogen: oxygen is 1:2:1
• contain C, H, O• energy =
4cal/gram

Carbohydrate
Structure: Functions:
Monomer: Polymer:
•Circle or ring shaped•Create a 1:2:1 ratio
Elements:•C, H, O
•Main source of immediate energy
Good to know:•Often known as simple (monomers) and complex (polymers)
•Monosaccharide•Examples: glucose, sucrose

Energy in Food
• Burning carbohydrates – watch and write down your observations
• Burning lipids – take notes and write down any observations
• Calories in food – take notes…MAKE SURE you write down how many calories per gram in each biomolecule AND the daily recommended allowance

Lipids are molecules that are not soluble in water. They are nonpolar
and hydrophobic.

• Fats
• Oils
• Waxes

Lipids can be used to:• Store energy.• Contain the most
energy per gram of any biomolecule. (9 Cal/gram)
• To form biological membranes and waterproof coverings.

Many lipids are formed when a glycerol molecule combines with compounds called
fatty acids.
