    Study Notes

    Building Blocks of Proteins

    • Amino acids are the primary building blocks of proteins, linking together to form peptide chains.

    Characteristics of Amino Acids

    • Amino acids have a central carbon atom, an amino group, a carboxyl group, a hydrogen atom, and a variable R group that defines each amino acid's unique characteristics.

    Functions of Amino Acids

    • Amino acids serve multiple functions, including being precursors for neurotransmitters, hormone synthesis, and supporting immune functions.
    • Functions NOT associated with amino acids include providing energy, as they are mainly used for biosynthesis rather than energy production.

    Types of Amino Acids

    • Essential amino acids cannot be synthesized by the body and must be obtained through diet, while non-essential amino acids can be produced by the body itself.

    Role in Enzyme Function

    • Amino acids are crucial for enzyme function as they form the active site of enzymes, facilitating biochemical reactions by lowering activation energy and stabilizing transition states.
