Hydrocarbons = Molecules containing only carbon and hydrogen

- Are major components of fossil fuels produced from the organic remains of organisms

living millions of years ago, though they are not prevalent in living organisms.

- Have a diversity of carbon skeletons which produce molecules of various lengths and

shapes.

- As in hydrocarbons, a carbon skeleton is the framework for the large diverse organic

molecules found in living organisms. Also, some biologically important molecules may have

regions consisting of hydrocarbon chains (e.g. fats).

- Hydrocarbon chains are hydrophobic because the C-C and C-H bonds are nonpolar.

What molecules in membranes allow lipids and water to mix?

Phospholipids are the main molecules in membranes that allow lipids and water to mix. They contain both hydrophobic (lipid-loving) and hydrophilic (water-loving) regions in their structure, enabling them to form the basic structure of cell membranes. The hydrophilic head interacts with water, while the hydrophobic tail interacts with lipid molecules.


How does the structure of fatty acids compare to the basic units found in other macromolecules?

Fatty acids are composed of a hydrophilic carboxylic acid head and a hydrophobic hydrocarbon tail, while basic units in other macromolecules (such as amino acids in proteins, nucleotides in DNA/RNA, and monosaccharides in carbohydrates) have different functional groups and structures specific to their roles in each macromolecule. The differences in functional groups and structure give these basic units unique properties and functions within their respective macromolecules.

How do phospholipids help control the passage of materials in and out of the cell?

They have a hydrophilic and hydrophobic region. The hydrophobic regions will face inward in a phospholipid bilayer, and the hydrophilic will face outward. This creates a bilayer that only allows small, nonpolar molecules through. It makes it difficult for larger macromolecules to pass through because the hydrophobic regions will not face the water inside or outside the cell.


What elements are used to make a fat moecule?

A fat molecule is made up of three fatty acid molecules attached to a glycerol molecule through ester bonds. The fatty acids consist of a long hydrocarbon chain with a carboxylic acid group at one end. The combination of these components forms a triglyceride, the basic structure of most fats.

How does phospholipid react in water?

Phospholipids are amphipathic molecules with a hydrophobic tail and hydrophilic head. In water, phospholipids spontaneously form lipid bilayers due to their amphipathic nature, with the hydrophobic tails facing inward and hydrophilic heads facing outward towards the water. This forms the basic structure of cell membranes, which separate the internal and external environments of cells.


What are subunits of Lipids?

Lipids are a group of hydrophobic chemical structures comprised of fats, oils, steroids, phospholipids, and waxes. The basic subunits of most of these are fatty acids, which have a hydrocarbon backbone and a carboxyl group at one end.

What is a basic structure of a cell membrane?

A cell membrane consists of a phospholipid bilayer with embedded proteins. The phospholipid bilayer is made up of two layers of phospholipid molecules, with hydrophilic heads facing outward and hydrophobic tails facing inward. The proteins in the membrane help to regulate transport of molecules in and out of the cell.

A phospholipid is usually?

A phospholipid is usually composed of a hydrophilic head (such as a phosphate group) and two hydrophobic tails (typically fatty acids). This structure allows phospholipids to form the basic building blocks of cell membranes due to their amphipathic nature.


What is the most basic component of the cell membrane?

Phospholipids are the most basic component of the cell membrane. They form a bilayer structure, with hydrophobic tails facing inward and hydrophilic heads facing outward, creating a semi-permeable barrier around the cell.
