Study Notes
- Water is an important inorganic molecule found in the human body, making up about 67% of our bodies.
- Water is a polar molecule composed of two hydrogen atoms and one oxygen atom, forming polar covalent bonds within the molecule and hydrogen bonds between separate water molecules.
- Solubility in water is determined by the polarity of substances, with polar molecules and charged ions being water-soluble, while non-polar molecules like oils and fats are water-insoluble.
- Substances that dissolve easily in water are considered hydrophilic, while those that do not are hydrophobic.
- Non-polar substances like oils and fats are lipid-soluble, while polar and charged substances are lipid-insoluble.
- Understanding solubility is important for various applications such as medication delivery and transportation through the body.
- Water-soluble substances can easily dissolve in the plasma, while lipid-soluble substances can cross cell membranes due to their non-polar nature.
