Macromolecules are molecules that are composed of thousands of atoms and are polymers of smaller molecules that are called monomers (basic building blocks). Some main examples of macromolecules are proteins, lipids, carbohydrates, and nucleic acids. Each macromolecule can be based on the foods we eat. Proteins are one of the most important macromolecules and its made out of amino acids. Lipids are organic compounds of fatty acids that are made up of glycerol. Carbohydrates are biological macromolecules that are divided into 3 subtypes such as monosaccharides, disaccharides, and polysaccharides. Nucleic acids are molecules that are composed of smaller molecular units called nucleotides and are linked like a chain.
Monomer: amino acids
Dietary Sources: lean meats, dairy products, eggs, fish
Functions in cells: Storage, Transport regulatory, Movement of structural enzymes
Examples: antibodies, contractile storage proteins
Monomer: Glycerol + Fatty Acids
Dietary Sources: nuts, soybeans, oil
Functions in cells: Energy storage, Forms cell membranes, Chemical messengers, Protection/Insulation
Examples: phospholipids, fats, oils, wax
Monomer: Monosaccharides (Simple Sugars)
Dietary Sources: fruits, vegetables, milk,
Functions in cells: Energy storage
Examples: glucose, fructose, galactose
Monomer: Nucleotides
Dietary Sources: vegetables, seeds, grains, fish eggs
Functions in cells: Carries genetic information to make proteins
Examples: DNA and RNA
Overall, I am proud of my groupmates for completing this project while I was absent for a week. They both worked really hard to get the results that they wanted and I'm happy that they did it without me. I also feel bad that I couldn't contribute any help during the process of the lab but I am satisfied with the results we got. It is unfortunate that my group got all mixed up with the directions to the lab so they came up with only one out of the four macromolecules for this lab. I learned a lot about macromolecules and their functionality between different ones coming back from my absence.
