Danny Marnell BioE 210 HW #2 1. 5) Molecules have the ability change their 3-D shape because covalently bonded atoms are able to rotate around while keeping its bonded state. 11) Amphipathic molecules have 2 different regions. The non-polar regions cluster together, while the polar regions form hydrogen bonds with water, which creates a “shell” around the non-polar cluster. 15) Carbohydrates, lipids, proteins, and nucleic acids make up the four classes of organic molecules in the body. 16) Carbohydrates are made up of monosaccharides, disaccharides, and polysaccharides. Monosaccharides are simple sugars which are made up of mostly 5 or 6 carbon atoms, with hydrogen and hydroxyl groups attached to each of the carbons. Disaccharides are two monosaccharides that have undergone dehydration to form a single molecule. Polysaccharides occur when many monosaccharides are linked together. 19) Subclasses of lipids are fatty acids, triglycerides, phospholipids, and steroids. Fatty acids are a chain of carbon atoms with hydrogen groups attached, and a carboxyl head. Triglycerides form when three fatty acids bond to glycerol, by way of dehydration of the carboxyl and hydroxyl groups. Phospholipids are similar to triglycerides, except the third hydroxyl of glycerol binds to a phosphate molecule. A nitrogen containing molecule also binds to the end of the phosphate molecule.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
