JordanThe four major types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are the main source of energy for living organisms. Lipids serve as energy storage molecules and form the cell membrane. Proteins have various functions such as structural support, signaling, and enzymatic activity. Nucleic acids store and transmit genetic information.
Macromolecules are formed by dehydration reactions in which water molecules are removed from the formation of bonds.
Carbohydrates
Carbohydrates typically have CnH2nOn formula. There are three types of carbohydrates, monosaccharides contain one sugar, disaccharides contain two sugars, and polysaccharides contain many sugars. Polysaccharides play important roles in cells such as energy storage (animal glycogen) and structure support (plant cellulose).
Proteins
Proteins are made of C, H, O, N and S. The building units of proteins are amino acids. Each amino acid contains an amino group, a carboxyl group, a central carbon and hydrogen, and an R group.
Lipids
Lipids are made of carbon, hydrogen and oxygen. Storage lipids include fats, oils and waxes. Mono-carboxylic acids, containing a long hydrocarbon side chain.
Nucleic Acids
Nucleic acids are made of carbon, oxygen, hydrogen, nitrogen and phosphate. The basic building blocks of nucleic acids are nucleotides. Each nucleotide has three basic parts: a nitrogenous base, phosphate group and a sugar.

Is this true or false Four major types of macromolecules are proteins carbohydrates lipids and glycerol?
False. Glycerol is not a macromolecule itself, but a component of lipids. The four major types of macromolecules are proteins, carbohydrates, lipids, and nucleic acids.
Which of four types of macromolecules contains units called monosaccharides?
Carbohydrates
Examples of macromolecules?
Examples of macromolecules include proteins, nucleic acids (DNA and RNA), carbohydrates, and lipids. These large molecules are essential for various biological functions in living organisms.
Which of the four types of macromolecules units called monosaccharides?
They are type of monomers. They build up carbohydrates.
What are examples of the four major macromolicules?
The four major macromolecules are carbohydrates (example: glucose), lipids (example: triglycerides), proteins (example: enzymes), and nucleic acids (example: DNA).
