Name four macromolecules and their monomers?
Four (bio)macromolecules are: Carbohydrates (e.g. Glucose, cellulose and lactose), Lipids (e.g. Triglyceride, phospholipids) , Proteins (e.g. Insulin, keratin and all enzymes) and Nucleic Acids (e.g. DNA and RNA).
1) Carbohydrates = Monosacharides
2) Lipids = Glycerol and Fatty Acids
3) Proteins = Amino Acids
4) Nucleic Acid = Nucleotide
Monomers and isomers are completely different. Monomers are building blocks of polymers/macromolecules. For example, amino acids are the monomers of proteins and monosaccharides are monomers of carbohydrates. Isomers, on the other hand, are molecules with the same number of atoms in a compound, but different arrangements of bonds or shapes.
Lipids: Carbon, Hydrogen and Oxygen - monomers are glycerol and fatty acids Proteins - Carbon, Hydrogen, Oxygen and Nitrogen - monomers are amino acids Carbs - No Phosphate. Carbon, Hydrogen and Oxygen - H:O ratio is 2:1 - monomers are monosaccharides (may have a ring structure) Nucleic Acides - examples are dna and rna. Carbon, Hydrogen, Oxygen, Nitrogen and Phosphate - monomers are nucleotides (sugar, phosphate, nitrogen base)
Lipids are unlike the other macromolecules in that they do not have monomers per se. They are made up of glycerol and fatty acids, but it's not like DNA which is made up of nucleotides or proteins that are made up of amino acids. However, they are still considered macromolecules as lipids are a large category of important molecules in the human body.
The four macromolecules found in living organisms are carbohydrates, lipids, proteins, nucleic acids: 1. Carbohydrates: Are Molecule composed of carbon, hydrogen, and oxygen, and they include sugars and starches. 2. Lipids: Are non polar molecule that includes fats, oils, and cholesterol. 3. Proteins: A Proteins is a polymer made of monomers called amino acids. 4. Nucleic Acids: Are polymer that are made up of monomers called nucleotides.
