- Amino acids have different side chains which determine function and reactivity
- Proteases break proteins down into small peptides or amino acids
- Proteins have primary structures and may have Secondary, Tertiary and Quaternary structures that increase their complexity and function
- Proteins can form alpha helices, beta barrels, beta sheets]]> 2022-01-19 03:19:52 UTC https://padlet.com/kste42231/uva56nri30l93jsn/wish/1999432457 avas7187 https://padlet.com/kste42231/uva56nri30l93jsn/wish/1999432964 17kJ/g

- Found in eggs, organs, skins. We cannot function without protein.

- Proteins are made up of a number amino acids. The human body can only produce about half of these naturally, and the rest can only be absorbed through diet
- The lifespan of most proteins averages less than two days
- Protein is the 2nd most abundant substance in the human body behind water. It is found in every single cell in your body.]]> 2022-01-19 03:41:50 UTC https://padlet.com/kste42231/uva56nri30l93jsn/wish/1999459083
