What part of the cell are phospholipids found?
Phospholipids are usually found in the cell membrane of a cell (hence the alternate name for a cell membrane being the phospholipid bilayer).
What us the density of 2A stone aggregate?
If by aggregate you mean the 'rock' mixed in to make concrete, then the density is usually about 2.7 g/cm3 .
The basic unit of the cell membrane is the?
Phospholipids.
Are phospholipids charged at pH 7?
Phospholipids are typically uncharged molecules at pH 7 as they have a neutral overall charge. The phosphate group in phospholipids is usually ionized and carries a negative charge, but the overall charge of the molecule is balanced by the other components, making it neutral.
What is concerete made up of?
cement powder mixed with an aggregate (usually gravel or sand) and water
Why Phospholipids are completely insoluble in water?
Water solubles have poles (partial positive or partial negative ends) which being attracted by the opposite poles of water (OH- & H+ respectively) causes the solution. Hydrophobic substances have no such poles.
Are the heads of phospholipids hydrophilic?
Yes, the heads of phospholipids are hydrophilic.
What will happen when Aggregate demand and aggregate supply decrease?
When aggregate demand and aggregate supply both decrease, the result is no change to price. As price increases, aggregate demand decreases, and aggregate supply increases.
Is Hemoglobin a phospholipids?
hemoglobin is composed of long chanins called phospholipids
What is the subunit of phospholipids?
Phospholipids are a class of lipids, which are major components of cell membranes. The three subunits of phospholipids are phosphate, glycerol and fatty acids.
How do phospholipids contribute to membrane structure?
Since phospholipids have a hydrophobic tail (does not like water) and a hydrophillic head (likes water) it is best for a membrane structure. For the tail, it's usually bent at one end so phospholipids can attach to each other and usually never separate. Here's a visual representation: For a membrane, the phospholipids connect until they make a circle to sorround what is inside of the cell, but it is a bilayer membrane which means there will be 2 circles of phospholipids which looks like this (ignore the yellow part): Since the hydrophobic part is facing each other, it keeps the phydrophillic parts outside and inside of the cell (look at the link above). That means the water that usually sorrounds the cell cannot get into the cell because the hydrophobic part is in between the hydrophillic part. The one that does not like water will not allow the water to get into the cell.
Where in eukaryotic cells is phospholipids made?
phospholipids are made in the smooth endoplasmic reticulum.
