Study Notes
Proteins and Amino Acids
- Not a function of proteins: undefined (awaiting specific information)
- The sequence of amino acids in a protein is determined by the genetic code in DNA
- A linear chain of amino acid residues is termed a polypeptide
- A peptide is considered a linear chain of fewer than 50 amino acid residues, whereas a protein is a longer chain
Biomolecules and Interactions
- Amino acid residues are bonded together in a protein through peptide bonds
- A macromolecule is a large molecule composed of many smaller molecules, such as proteins, carbohydrates, and nucleic acids
- Hydrogen bonds maintain the structure of molecules by forming between a hydrogen atom and an electronegative atom
- Biomolecules are composed of monomers, such as amino acids, sugars, and nucleotides
- Hydrogen bonds are a type of molecular interaction that forms between a hydrogen atom and an electronegative atom
Nucleic Acids
- Nucleic acids, such as DNA and RNA, are composed of nucleotides as their macromolecules
Test your knowledge about proteins and their diverse functions in organisms. Learn about the differences between various protein types and their roles in catalysis, DNA replication, cellular structure, and molecular transportation.
