Synopsis of The 3 Parts
Part 1: This was designed to test four different methods of cheese production so that we may find the most effective curdling agent
Part 2: This second portion was a variation of the first test, where each group changed a variable in their procedure. For us, this was incubation temperature
Part 3: Our last part was designed for us to see the macro-molecules found in cheese. We tested with positive and negatives, then with our cheese.

Concepts
Macromolecules: Macromolecules are large molecules that include the following four concepts.
Carbohydrates: There are two types of Carbs that we focused on, which were monosaccharides and polysaccharides. Monosaccharides are simple sugars that store energy, an example is glucose (C6H12O6). Polysachharides are a multi-ringed structure instead of a single ring, like the monosachharides. These store energy, help in cell structure, and act as markers for protein transport. We saw Monosaccharides in our lab, but not Polysaccharides.
Lipids: Lipids is commonly known as fats and oils. Our cheese lab contained lipids. There are three major things that lipids do. They form the cell membrane through Phospholipids, store energy through fatty acids, and act as cell signalers and messengers.
Nucleic Acids: Nucleic acids are the genetic code of eukaryotic cells. They also make protein synthesis, catalyze reactions, and transfer information. deoxyribonucleic acid (DNA) complementary base pairs are cytosine and thymine, and adenine and guanine. ribonucleic acid (RNA) is the same, but replace thymine with uracil. The sugar backbone of DNA and RNA is formed by the binding of a hydroxyl group with a phosphate. We never tested this in our lab.
Proteins: Proteins are made to carry out tasks given to them, and they are made according to their function. Some functions are transportation, structural support, carrying information, etc. Polypeptides are the code to what a protein is. A polypeptide is a series of peptide bonds, which are made of 20 different amino acids. We did find protein in our cheese lab.

Reflection
Reflection: There were multiple positives and negatives. Positives: I was able to follow the procedure without any major bumps in the road. Secondly, I learned how to isolate a variable and change it independently. Negatives: There was the smoke in the air which, combined with my asthma, made it not easy to breathe. I wasn't working at my best because of this, so I should have stayed home instead of pushing myself. Secondly, There was an issue where another group thought we were copying their change for the second part of the lab (incubation through hotter water). We didn't know they had that idea until we both started doing it. While we both did it anyway, I should have been louder and made sure everyone knew my idea.
