Lipids In Cell Membranes
BASIC CHEMISTRY 1. What is the difference between being ionized and being polar? When ionized the atom will either lose or gain electrons. A polarized molecule has an overall neutral charge with positive and negative sides such as H2O. 2. Compare macromolecules to Monomers; complete the chart below Example of a Macromolecule | Corresponding Monomer | polysaccharide | monosaccharide | lipids | glycerol, fatty acid | protein | Amino acids | nucleic acid | necleotides | CARBOHYDRATES 1. List the three main groups of carbohydrates. The three main group of carbohydrates are monosaccharides, disaccharides, and polysaccharides 2. Play the animation of dehydration synthesis. What two monosaccarides did you start with? What

Which of the following are also found in the cell membrane: lipids, proteins, or carbohydrates? What is the role of steroids in a cell membrane?
Cell membranes contain all three of the above groups, lipids are found abundantly in cell membranes, steroids are a type of lipids which helps with membrane fluidity by restricting the motion of the fatty acid tails.
PROTEINS
1. Scroll down to proteins. List the six functions of proteins listed. What are the units of a protein and how are they connected? Proteins can be categorized into transport, hormonal, receptor, enzyme, regulatory, and structural proteins. The basic unit of a protein is an amino acid. Amino acids are linked by peptide bonds to form polypeptides. 2. Proteins can be small or large. The larger they get causes them to fold. List the four types of structures in which they can fold. Since they are held in this folded place by hydrogen bonds, what is it called when you heat a protein and ruin its structure? Proteins fold in a primary, secondary, tertiary, and quaternary structure. Each structure is a combination of the ones before it. When these folds are damaged, denaturing
