Homeoviscous adaptation is the adaptation of the cell membrane lipid composition to keep the adequate membrane fluidity.

 In general is an altering the length and degree of saturation of fatty acids in their membranes by increase unsaturated fatty acids at lower growth temperatures and an increase in saturated fatty acids at higher temperatures.

hydropathy plot

Hydropathy plots allow for the visualization of hydrophobicity over the length of a peptide sequence. A hydropathy scale which is based on the hydrophobic and hydrophilic properties of the 20 amino acids is used. A moving "window" determines the summed hydropathy at each point in the sequence (Y coordinate). These sums are then plotted against their respective positions (X coordinate). Such plots are useful in determining the hydrophobic interior portions of globular proteins as well as determining membrane spanning regions of membrane bound proteins.

 

Hydrophobic

Hydrophobic is a property of a substance that repels water.  Hydrophobic materials often do not dissolve in water It means lacking affinity for water, and tending to repel or not to absorb water.  Hydrophobic molecules tend to be non-polar molecules and group together, for example Oils and fats are hydrophobic and it is found in the tail , The opposite of hydrophobic is hydrophilic, water-loving this found in head .
