Functions of Biomolecules in living beings

1. Carbohydrates

   • Provide energy for working muscles
   • Provide fuel for the central nervous system
   • Enable fat metabolism and prevent protein for being used as energy
   • Work as fuel for muscle contraction and biologic work

2. Proteins

   • Form part of the structural part of the body
     • Keratin
     • Actin and myosin
   • Nutrition
     • Albumin
   • Work in communication and defense against pathogens

3. Nucleic Acids

   • Carry the genetic message of the cells
   • ATP
     • Energy transporter
   • Cyclic AMP
     • Messenger for hormonal regulation
   • DNA and RNA
     • Storage, transmission and translation of genetic information

4. Lipids

   • They store energy
   • Participate in muscle contraction
   • Insulators
   • Make up part of the cell membrane
