Essential Question How do the different macromolecules meet our needs?

Macromolecules

Carbon atoms have unique bonding properties. Carbon molecules form covalent bonds with up to four other atoms, including other carbon atoms. • Carbon-based molecules have three general types of structures. – straight chain – branched chain – ring

Many carbon-based molecules are made of many small subunits bonded together. – Monomers are the individual subunits. – Polymers are made of many monomers.

Macromolecules They are Polymers There are four distinct macromolecules that are also carbon based found in all living things

Four main types of carbon-based molecules are found in living things. Carbohydrates are made of carbon, hydrogen, and oxygen and provide quick energy – Monomers are simple sugars.

• Lipids are nonpolar molecules grouped together called glycerols – Each carbon chain is called a fatty acid. Triglyceride

Lipids have several different functions. – broken down as a source of energy – make up cell membranes – used to make hormones

Proteins are polymers of amino acids (monomers). – Twenty different amino acids are used to build proteins in organisms.

Proteins differ in the number and order of amino acids. – This determines its function to build muscles Hemoglobin hydrogen bond – Incorrect amino acids change a protein’s structure and function.

Nucleic acids are polymers of monomers called nucleotides.

• Nucleic acids are polymers of monomers called nucleotides. • DNA stores genetic information. – RNA builds proteins. DNA RNA
