Water
Water as a coolant in sweat
sweat gets heat away from our bodies
when swat evaporates it releases energy from our body
the skin and blood vessels are cooled
Thermal properties of water
high specific heat capacity
water as a coolant
temperature of water is relatively stable
Amino Acids
Positive and negative charges meaning it is soluble in water
it can be polar, non polar or charged
Carried by the blood plasma
Substances can be hydrophilic or hydrophobic
Hydrophilic: means water loving, this substances are attracted to water, all substances that dissolve in water are hydrophilic
Hydrophobic: hates water, all lipids are hydrophobic including fats and oils. they are non polar
Water molecules are polar and hydrogen bonds form between them
hydrogens bonds are electrostatic attraction between polar molecules
hydrogen bonds form between H and the following atoms: N,O,F
Modes of transport of glucose
carried by the blood plasma
polar molecule so it is freely soluble
