Lipids 5.3 Lipids Lipids include _______ and ___________ Characteristics: ________________ (____________________) Act as a _________________ that surrounds the _____________________________________ Help ______________________ from cell to cell Store _______________________ in your body Act as ______________________ Fats ________________ (3- carbon backbone) attached to __________________ that have hydrocarbon chains ____________, _______________, _________________ Saturated fat Fat in which __________________________ contain the ___________ possible number of ____________________ _______________________________________ Ex. Lard and butter; _________ at room temperature ________________ buildup leads to heart disease Fats Unsaturated Fat A fat that contains ____________________ number of ______________ atoms in ________________ of the fatty acid chains Bonding is different Some of the carbons are ______________ Ex. Corn oil, olive oil, and other vegetable oils Fats Is this fat saturated or unsaturated??? Steroids A _________ that contains _________________ of the carbon skeleton Ex: ___________________________________ How are there different types of steroids if they all have the 4 fused rings? __________________________________ __________________________________ Steroids Steroids _______________________ Type of steroid Found in ___________________________ Essential Also needed as a _____________________ __________________________________ Although it is needed, high levels in the blood can lead to _________________________ Concept Check What property do lipids share? What are the parts of a fat molecule? Describe two ways that steroids differ from fats. What does the term unsaturated fat on a food label mean? Proteins 5.4 Proteins ______________ Perform Most Functions in Cells _________________________ _________________________ _____________________________________________ _____________________________________________ Proteins are ____________ made up of ________ types of _______________________________ The whole point of making DNA is to make _______________ (hair, muscle, skin, etc) _____________________________ Proteins Amino Acids ______________________________________ ______________________________________ 3 are the same in all amino acids: ____________________ ____________________ ____________________ The only difference between amino acids is the _______________(_______________) Each side group has a different function depending on the function of the amino acid 20 types Proteins Proteins Building a Protein Proteins are made by _____________________ ____________ called ____________________ Amino acids are linked together by ________________ through _____________________ reactions _____________________ from between amino group of one amino acid and carboxyl group of the other amino acid Most polypeptide chains are at least _______ amino acids in length Lots of combinations of 20 amino acids to make many types of ______________ (like letters in alphabet form lots of different words) Proteins Protein Shape Need ___________ in order to _____________ properly Think yarn vs. finished sweater ___________________: protein loses shape due to temperature/pH/environment “____________________” Causes _____________________ Concept Check Give at least two examples of proteins you can "see" in the world around you. What are their functions? Relate amino acids, polypeptides, and proteins. Explain how heat can destroy a protein. Which parts of an amino acid's structure are the same in all amino acids? Which part is unique? Enzymes 5.5 Enzymes _____________________: __________________________________________ __________________________________________ Breaks bonds in molecule so that atoms can ____________ ___________ is a common way to provide activation energy but could destroy cells Therefore, _____________ are used: ______________________________________________________ ______________________________________________________ The main catalysts in organisms are called ___________ Enzymes don’t supply activation energy to reacting molecules. They ____________________________________________ ________________________________________________ Enzymes Enzymes How Enzymes Work: _____________________________ Molecule that enzyme works on is called a _________________ Substrate fits like a “________” into the enzyme (“___________”) Area where substrate binds is called the _________________ The bonds in the ______________ are ____________, and a reaction occurs new products Enzymes Enzymes Concept Check Explain the role of activation energy in a reaction. How does an enzyme affect activation energy? Describe how a substrate interacts with an enzyme.
