macromolecules notes
learning target:
in this lesson, i am learning the major characteristics of the four different categories of macromolecules. ill know i have it when:

• i can name the four categories of macromolecules.
• i can describe the elements and basic structure of each macromolecule.
• i can list two functions for each macromolecule.

part 1: guided reading
access the pdf here to read about the four types of macromolecules, and use this knowledge to answer the questions that follow.

1. how are monomers and polymers related?

1. what are four main types of macromolecules found in living things?

1. a protein is made up of monomers called

1. the carbon chain that makes up part of a lipid is called

Explanation:

1. Polymers are made by linking monomers together through chemical bonds. For example, many glucose monomers can link to form the polymer starch.
2. The four main types of macromolecules in living things are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates provide energy, lipids are for energy - storage and insulation, proteins have various functions like catalyzing reactions and forming structures, and nucleic acids store and transmit genetic information.
3. Proteins are made up of monomers called amino acids. There are 20 different amino acids that can be combined in various sequences to form different proteins.
4. The carbon - chain that makes up part of a lipid is called a fatty acid. Fatty acids can be saturated or unsaturated depending on the presence of double bonds in the carbon - chain.

Answer:

1. Polymers are formed by linking monomers.
2. Carbohydrates, lipids, proteins, nucleic acids.
3. Amino acids.
4. Fatty acid.
