1. Vitamins – micronutrients Organic Fat or water soluble
Table 35

2. Vitamin deficiency Vitamin fortification
To what extent is mass medication through the food we eat an infringement of personal freedom?
Is there a way to strike balance between the claim of scientists/government to knowing what is best for health vs. right of an individual to choose what to eat?

4. Pigments - intense absorption bands, color that is seen is reflected
Table 35
Because…
Highly conjugated = p orbital electrons are delocalized in benzene rings structures
E- not held as tightly so become excited
Chromophore – part of molecule that absorbs the radiation
chromophore

5. Porphyrins
Big rings
Nitrogen-containing
Ligand with metals

6. Chlorophyll

7. Hemoglobin – heme group

8. Cooperative binding of O2 to Hb

9. High temp, exercise so need to O2
High CO2 (low pH), need O2 released

10. Fetal = 2 alpha and 2 gamma

11. Cytochromes Responsible for electron transport
Difference: Fe become reduced and re-oxidized

12. Carotenoids
Accessory pigment in photosynthesis

13. Anthocyanins
Formed in reaction between sugars and proteins requiring light
Sensitive to pH – can be used as indicators
