The first thing we did in class today was see our shirts we tie dyed on Friday. Everyone’s turned out great and was happy with the way it looked except for Nick whose shirt turned out looking very girlie. Next, our instructor showed us his virtual AP Bio café which he plans top eventually make national. The virtual café was really interesting and cool to see someone’s idea shown through a computer. When our instructor was done showing us his café, we moved on to notes.
These notes were a continuation of chapter 5 about macromolecules. The first topic was lipids; before today I didn’t know lipids and fats couldn’t be used interchangeably: fats are a type of lipid. Lipids are a long hydrocarbon chain and have 3 groups: fats, phospholipids, and steroids. Fat is a long HC chain that is non polar and hydrophobic. The two types of fats we learned about were saturated and unsaturated fats. Phospholipids consist of 2 fatty acids and PO4. The fatty acid tail is hydrophobic and the PO4 is hydrophilic. Steroids such as, cholesterol and sex hormones are 4 fused C rings.
Next we learned about Proteins which have many functions. The structure of a protein is a monomer which is an amino acid. We also learned about what determines the order of amino acids but unfortunately we didn’t have enough time to complete the lesson.
