Building 4 Biological Molecules
Carbohydrates, Amino Acids, Nucleotides, Lipids
Observe: 1. Carbohydrates (monosaccharides, disaccharides, polysaccharides), Lipids (of many kinds, including, triglycerides, phospholipids, and steroids, such as testosterone, estrogen, and cholesterol), Proteins (including enzymes, lipoproteins, glycoproteins, structural proteins, hormones, etc), and Nucleotides ( nucleotides join to form nucleic acids, which, along with a sugar and phosphate group, build DNA, RNA, and ATP)
Problem Statement: 1. Will making models help to better understand the form and function of these 4 types of biological molecules and their subgroups?
Hypothesis:
1. Yes, I think that making the molecules will help understand the 4 types of biological molecules and their subgroups, because, it will give a visual prospective.
Purpose(s):
1. To better understand each type of biological molecule discussed in Chapter 3 2. To understand what subgroups are 3. To understand monomers and polymers 4. To understand the structure of these biological molecules 5. To understand what their functions are in the body
Materials:
1. Black=Carbon 2. Red=Oxygen 3. Yellow=Hydrogen 4. Purple=Phosphorus 5. Orange=Nitrogen 6. Toothpix=Bonds 7. Ribbons to make amino acids 8. Nucleotide puzzle (part 2)
Procedure: 1. CARBOHYDRATES 1. Build this portion of the glucose molecule
(Monosaccharide: Glucose: C6H12O6)
2. Now build a second molecule and place besides the 1st
(Two monosaccharides: Two Glucose: C6H12O6)
3. Remove the HYDROXYL group (-OH) from 1 glucose molecule and the hydrogen part of the HYDROXYL group from the other. (H2O is a byproduct) and (Disaccharide: Maltose: C12H22O11 is formed)
4. Re-place the HYDROXYL group (-OH) and hydrogen in the corresponding glucose molecules
2A. AMINO ACIDS TO POLYPEPTIDES TO PROTEINS
5. Build an Amino Acid
