Biomolecules (Updated 2023) 

Explore the four biomolecules and their importance for organisms and the structure and function of their cells! This 2023 UPDATED Biomolecules Amoeba Sisters video has some more detail and improved art from the 2016 Amoeba Sisters biomolecules video. The old 2016 biomolecules video • Biomolecules (Older Vi... will remain up in case you prefer it. The biomolecules (carbohydrates, lipids, proteins, and nucleic acids) can all can have important functions in the body. As mentioned for the old 2016 video, this video is not giving human dietary guidelines - for your dietary needs, consult with a dietitian or medical doctor.

FURTHER EXPLORATION MENTIONED IN VIDEO:
CARBOHYDRATES:
Want to see a diagram of two carbohydrates connected by a glycosidic linkage (bond)? openstax.org/books/biology-2e...
LIPIDS:
Lipids do not have a true polymer or true monomer. [Because they don't have a true polymer, many sources will include them as a non-polymeric macromolecule]
Why do lipids lack a true monomer? Unlike the others, they do not have a repeating unit.
NUCLEIC ACIDS:
If there are nucleic acids like DNA in my food, what happens to them? Check out this article from "The Conversation" (we like "The Conversation" as it partners scientists with journalist) written by a professor of molecular biology. theconversation.com/is-eating...
