  1. Can form hydrogen bonds with water molecules

    Form hydrogen bonds with other polar molecules

    Can interact with positively or negatively charged ions
  2. 1. Can be either simple or complex sugars
    2. Their main function include:
    Major source of nutrients
    starting material for other cell constituents
    when conjugated to proteins to different cell locations
    as surface markers, play important roles in cell recognition and intracellular interactions.
  3. 1. Non polar molecules that consist of long chains of hydrocarbons
    2. Their functions include:
    a form of energy storage
    Major components of membranes
    Important roles in cell signaling as steroid

    Hormones and as messenger molecules
  4. 1. These are the [rinciple information molecules of the cell
    2. Their functions include:
    Making up genetic material
    transfer info from nucleus to cytompasm
    catalyzing reactions (protein synthesis)
    Serving as template for protein synthesis
  5. 1. These are the building blocks that execute the task directed by the information encoded in genes
    2. Their functions include
    forming structural components of the cell
    transporting and storing small molecules
    transmiting information between cells
    providing defense against infection
    to function as enzymes
  6. 1. Organic ions
    2. are involved in a number of a cell processes
    co-enzymes
    signaling messengers
    buffer systems
  7. Regular arrangement of aminoacids within localized regions of the polypeptide
  8. The folding of the polypeptide chain as a result of interactions between the side chains of aminoacids that lie in different regions of the primary sequence
  9. The interactions between different polypeptide chains in protiens composed of more that one polypeptide
  10. Polypeptides form proteins upon proper folding the 3D stat of the chain this is due to the constituent aminoacids so the shapes of proteins are determined by their s amino acids sequences
  11. Polypeptide chain coil around itself, with the CO group of one peptide bond forming a hydrogen bond with the NH group of a peptide bond located four residues downstream in the linear polypeptide chain.
  12. Two or more parts of a polupeptide chain that lie side by side with hydrogen bonds between them; can be oriented either parallel or anitparallel to each other
