Hydrophilic (water-loving) or could be called water, it mean attracting water molecules as close as possible, the phospholipid is made up of a head that is polar, and a tail that is non polar or in another words called “hydrophobic” , this means that the head of the phospholipid is attracted to water molecules ( this helps you understand the structure of cell membrane formation). Steriod, a class of lipids, some hormones like cholesterol are made up of steroids. They maintain fluidity of cell membrane. Example: oestrogens
Answer:
A. Cadherins in desmosomes would no longer be anchored to intermediate filaments
Explanation:
Cadherins are Ca dependent molecules (proteins) that are involved in cell-cell adhesion (they are type of cell adhesion molecule-CAM). Cadherins are composed of: a small cytoplasmic component, a transmembrane component, and the extra-cellular part.
There are types of cadherins called desmosomal cadherins which are involved in the formation of desmosomes (structure for cell-cell adhesion) and they bind to linker proteins and keratin intermediate filaments.
