day 10 of cell biology glossary
Show Answers:

  1. Glycerol
    A subunit of lipids, it is a simple polyol (sugar alcohol) compound
  2. Integral protein
    Typically transmembrane proteins with hydrophobic regions that completely span the hydrophobic interior of the membrane.
  3. Lpids
    Lipids are made of subunits, namely glycerol and fatty acids, they are not polymers
  4. Monosaccharide
    The simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH2O.
  5. Peripheral protein
    Protein appendages loosely bound to the surface of the membrane and not embedded in the lipid bilayer.
  6. Phospholipid
    A molecule that is a constituent of the inner bilayer of biological membranes, having a polar, hydrophilic head and a nonpolar, hydrophobic tail.
  7. Phospholipid bilayer
    membranes are composed of a phospholipid bilayer – that means there are two layers of phospholipids arranged with their hydrophobic tails shielded from the aqueous environment of the cell and the hydrophilic heads in contact with it.
  8. Polysaccharide
    A polymer of up to over a thousand monosaccharides, formed by dehydration reactions.
  9. Saturated fat
    Fatty acid tails with NO double bonds
  10. Starch
    Plant Storage Polysaccharide
  11. Unsaturated fat
    Fatty acid tails with one or more double bonds
