what macromolecule is a phospholipid?

Phospholipids are like fats but they have two fatty acids and a phosphate group joined to glycerol. The fatty acid tails are hydrophobic but the phosphate part is hydrophilic. This is an important feature of these molecules.

Phospholipids are similar to triglycerides, but they do vary slightly in form and function. While triglycerides have glycerol and three fatty acids, phospholipids have glycerol, two fatty acids and a phosphate. Phosphates are molecules with charges and have oxygen and phosphorus. ... Fat cells do not store phospholipids.

Phospholipids and the Lipid Bilayer In phospholipids, the two fatty acids are hydrophobic, or insoluble in water. But the phosphate group is hydrophilic, or soluble in water. When phospholipids are mixed with water, they spontaneously rearrange themselves to form the lowest free-energy configuration.

Answer Expert Verified The answer is D. The reason for this is, as stated in your question, it is called a phospholipid bilayer.

Phospholipids are unusual yet important to cell membrane structure because they: A) are part of DNA.

-Phospholipids have two hydrocarbon tails, whereas detergents have just one. -Phospholipids form bilayers in water, whereas detergents tend to form micelles. -Detergents are shaped like cones, whereas phospholipids are more cylindrical. -Phospholipids are hydrophobic, whereas detergents are amphipathic.

Macromolecules are huge molecules made up of smaller subunits called monomers. There are two types of macromolecules - organic (those found in living things) and inorganic (those found in things not living). Organic macromolecules include four classes - proteins, carbohydrates, lipids and nucleic acids.

The term macromolecules refers to large molecules that are built from smaller subunits. When all the subunits are of the same type the macromolecules are called polymers and the subunits are monomers. When the subunits are of different types they are simply referred to as macromolecules.

Phospholipid Definition. A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule.

A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.

Lipids. Unlike the other macromolecules, lipids are not soluble in water, and they don't form long sequences made up of similar or repeating smaller units. The fats you consume are molecules called triglycerides, consisting of three fatty acids attached to a glycerol.

Phospholipids, the principal components of cell membranes, consist of two fatty acids joined to a polar head group (Figure 2.7). In the glycerol phospholipids, the two fatty acids are bound to carbon atoms in glycerol, as in triacylglycerols.

The phospholipid bilayer is composed of two layers of lipids. Each lipid contains a hydrophobic (water repelling) tail and a hydrophilic (water attracting) head.

Phospholipids are crucial for building the protective barrier, or membrane, around your body's cells. In fact, phospholipids are synthesized in the body to form cell and organelle membranes. In blood and body fluids, phospholipids form structures in which fat is enclosed and transported throughout the bloodstream.

Phospholipids. The membrane bilayer contains many kinds of phospholipid molecules, with different sized head and tail molecules. These consist of a head molecule, a phosphate molecule, a glycerol and two fatty acid chains.

Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.
