Bellwork:•Get out your lab•Review your questions, and summary

with your group (4 Min)•Copied and answered questions (HW)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

Objective: The objective of class today is to learn the structure and

function of carbohydrates and lipids in living systems.

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.

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.

Three examples of a polysaccharide include:

Carbohydrates• Rings that link

together in chains

• contain C, H, O• Ratio of carbon:

hydrogen: oxygen is 1:2:1

• energy = 4 cal/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

•Polysaccharide•Examples: starch, cellulose

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
