The structures of the fatty acid tails. They can either be "saturated" or "unsaturated," which refers to hydrogens. If a fatty acid tail is saturated, then the carbon skeleton is bonded to as many hydrogens as possible. These are single C--H bonds so one carbon pairs with two hydrogens. An unsaturated fatty acid carbon may be double bonded to one hydrogen only. The double bonding causes "kinks" in the tails, causing them to be sort of "jumbled". Because the tails don't line up in unsaturated lipids, the freezing point is effectively lowered. Aquatic organisms in the Northern hemisphere have a higher concentration of unsaturated fatty acid chains in their lipid bilayer to preserve it's fluidity during the winter months.
Another factor is cholesterol: a lipid (steroid) that lies between the fatty acid tails. This too affects the fluidity of the membrane.
What else can I help you with?
What are the example of fluidity?
Examples of fluidity include water flowing in a river, gases expanding to fill a container, and people moving smoothly through a crowded space. Fluidity refers to the ability of a substance or system to flow and change shape easily.
The molecules in a room-temperature glass of water jostle around at?
Room temperature glass of water, the molecules are in constant motion and jostle around due to thermal energy. This motion is random, causing the molecules to collide with each other and the walls of the container. This activity contributes to the fluidity and equilibrium state of the water.
What is associated with water?
Water is often associated with the concepts of purification, renewal, life, and emotion. It symbolizes cleansing, adaptability, and fluidity. Water is also linked to intuition, spirituality, and the subconscious mind.
What are some modulators of membrane fluidity?
Some moderators of membrane fluidity are the proteins embedded in it and cholesterol molecules also.
How do a phospholipid behave in water?
In water, phospholipids spontaneously arrange themselves into a bilayer due to their amphipathic nature; they have hydrophilic (water-attracting) heads that orient towards the water and hydrophobic (water-repelling) tails that face inward, away from the water. This arrangement forms the foundational structure of cell membranes, allowing for the formation of a semi-permeable barrier. Additionally, the bilayer's fluidity enables the movement of proteins and other molecules within the membrane, essential for various cellular functions.
What Can't be compressed much but can move about?
Water is an example of a substance that cannot be compressed much due to its incompressibility, but it can move about freely due to its fluidity.
Why is the fluidity of oil lesser than that of water?
oil is more viscus than water
What is the function of water in the circulatory system?
osmregulation, thermoregulation, fluidity, dissolution, etc

Why does water decrease friction and makes things slippery?
Water acts as a lubricant, reducing friction between surfaces by creating a layer that allows them to slide past each other more easily. This is due to the low viscosity and high fluidity of water, which helps to smooth out imperfections on the surfaces in contact, making them slide with less resistance.
How does cholesterol impact membrane fluidity?
Cholesterol helps regulate membrane fluidity by interacting with the fatty acid tails of phospholipids in the cell membrane. It can decrease fluidity at high temperatures and increase fluidity at low temperatures, maintaining the stability and flexibility of the membrane.
