Animals cannot make these pigments
Humans get them from
- animals that eat pigmented plants
- eating pigmented plants
These pigments are
- defense against diseases
-
protection from heat
- plants need them for the hot summer temperatures
- high in lungs to protect from heat such as a sauna or fever
- protects the structure from destruction during
- heat exposure
- fever
- kills germs, including Covid-19
- protects lungs during infections
- released when burned
- high in rubber to give the black smoke
- burning molecules releases them
- these pigments are key in exhaust, burning
Pigments decline as we age:
- loss of hair color
- pale skin when sick
moving to more technical
- Isoprene - the bases of these pigments
- carotinoids are based on isoprenes
- learn about the haze over cities
- why global warming is not actually carbon dioxide
- Isoprene - (inorganic)
- emissions per year
- CO2 - carbon dioxide (organic)
- emissions per year
A source of haze
Scientists identify how a hydrocarbon commonly emitted by plants is converted to light-scattering aerosols
