Carbohydrates are compounds made up of carbon, hydrogen, and oxygen atoms. contains monosaccharides (single sugar molecules). use it as main source or energy
Lipids are made up mostly from carbon and hydrogen atoms. some lipids are formed when a glycerol molecule combines with fatty acids.
Nucleic acids contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers assembled from individual monomers called nucleotides. they store and transmit hereditary information. the 2 kinds are RNA and DNA
Proteins contain nitrogen as well as carbon, hydrogen, and oxygen. they are polymers of molecules called amino acids.Some proteins control the rate of reactions and regulate cell proccesses . some are used to form bones and muscles. others transport substances into or out of cells or help fight disease

What characteristics of lipids enables macromolecules to repel water?
hydrophobic
Which of macromolecules cannot dissolve in water?
Lipids are not dissolving,. They have a hydrophobic part
Lipids are described as being what or water-hating?
Lipids are hydrophobic macromolecules. Literally it means "fear of water", and that water cannot easily diffuse across lipid membranes.
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 group of macromolecules does cholesterol belong?
Cholesterol molecules are considered to be lipids since they are a class of steroids which are lipids. Cholesterol is hydrophobic due to its hydrocarbon composition; this is a commonality within lipids.

Lipids differ from other large biological molecules in that they?
Lipids are different from other macromolecules because they are hydrophobic and don't dissolve in water.

What macromolecules make up the cell membrane?
The cell membrane is composed of a bilayer of phospholipids, which are composed of a glycerol molecule chemically combined with a polar hydrophilic phosphate head and two hydrophobic fatty acid tails.
Is cholesterol hydrophobic or hydrophobic?
Cholesterol has many hydrophobic side chains and a single hydrophilic side chain. Because it contains both hydrophilic and hydrophobic groups, it is amphipathic.yes cholesterol Hydrophobic , choestol not soluble in water
Is vitamin A hydrophobic or hydrophilic?
hydrophobic
What is hydrophobic and how do you determine if a molecule is hydrophobic?
Hydrophobic means that the molecule is repelled by water. You can tell if a molecule is hydrophobic by the way the atoms are arranged.
How are lipids held together?
Lipids are one of the four major macromolecules but they are NOT true polymers because their individual lipid molecules are NOT connected by covalent bonds. Instead one lipid molecule is connected to another lipid molecule by hydrophobic interactions.
Does nonpolar means hydrophobic or hydrophilic?
Nonpolar means hydrophobic.
