A water loving molecule!
the inside of it, the phospholipid's tails
What determines a molecule's solubility degree in water is its polarity. Equals dissolve.
The term "hydrophobic" refers to substances that do not interact well with water and tend to repel it. Hydrophobic molecules are typically nonpolar and do not dissolve in water, making them crucial in various biological and chemical processes, such as the formation of cell membranes. In contrast, hydrophilic substances are water-attracting and can dissolve in water.
cohesion-- Water molecules stick to each other. adhesion-- Water molecules stick to other molecules. Water is a polar molecule because of oxygen is more electronegative. Hydrogen bonds create surface tension and result it water's cohesive and adhesive properties. Hydrophobic = repel water Hydropholic = affinity for water. ...... hahaha XD
In a dual layer; the tails are facing towards each other, so there is a layer of phospholipid heads on the outer surface of the cell membrane, & another layer of heads on the inner surface of the membrane.
Two layers of phospholipids are arranged as a bilayer that forms the basis of cell membrane structure. One layer has its hydrophilic heads neighbouring the surroundings whereas the other has its hydrophilic heads neighbouring the cytoplasm. The hydropholic fatty acid tails of both layers of phospholipid point towards the centre.
The hydrophilic end of the phospholipid is the end that is attracted to water. Only the hydrophilic end will come in contact with the water. The other, hydrophobic ends, will face inward and touch each other.
