LS1 6 Atoms from Sugar forming Macromolecules

Project Zero THINKING ROUTINES

HS-LS1-6.    Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.
[Clarification Statement: Emphasis is on using evidence from models and simulations to support explanations.] [Assessment Boundary: Assessment does not include the details of the specific chemical reactions or identification of macromolecules.]

Making Protein Crystals in Space

There are 100,000 different proteins in the human body

Studying the structures with X-ray crystallography or neutron diffraction help scientists learn more about them--perhaps to develop medicines, or synthesize them artificially

Better diffraction results occur with better crystals and growing crystals in space in a microgravity environment gets better crystals

Carbohydrates, Proteins and Lipids

Carbohydrates

Lipids

Carbohydrates are complex sugar molecules that are made up of long chains of monosaccharide units known as polysaccharide molecules.

​

 

Monosaccharides include glucose, fructose, and galactose.

​

 

Carbohydrates provide the energy required by all cells in the body.  Cells use glucose in the respiration process to carry out metabolic activities

Disaccharide

examples sucrose and galactose

Polysaccharide

examples starch and cellulose

​

Function of carbohydrates:

 

Digestive enzymes break down polysaccharides (ex. starch) so they can be absorbed by the body. Monosaccharides ex. glucose and fructose release energy from cellular respiration--releasing energy for cell processes

Carbohydrates are precursors for metabolic reactions including the synthesis of macromolecules such as fats, nucleic acids, and amino acids

Glycogen is a storage form of carbohydrates–-energy reserves in liver and muscles

Cellulose provides the support structure for plants

Proteins

Proteins are chains of amino acids linked together by peptide bonds and folded into a specific 3D structure that also have crosslinks, such as disulphide bridges, between specific amino acids to hold it in shape.

 

>20 amino acids are required for good health, our bodies can only make 14 of these essential amino acids, thus the others essential amino acids can only be obtained from food
