Document Summary
Lipids: water-insoluble organic biomolecules, made up of nonpolar groups, structural components of cell membrane (ex. Phospholipid: storage and transport forms of fuel, form protective surface coating, cell component in cell recognition, hormone. Fat types: saturated (butter, saturated with hydrogens, no double bonds between adjacent carbons, unsaturated (canola oil, double bonds between adjacent carbons, results lower melting/freezing point. Melting points differ: saturated fats are solids at higher temperatures than unsaturated fats, acyl chains of unsaturated fats are kinky and therefore require a lower temperature to become solid. Camel: up to 20% of body mass is fat when food is plentiful, subcutaneous fat would cause thermoregulatory problems. Human: normal weight 40-day reserve of energy, moderately obese- up to a year worth of energy stored. Nucleic acids: nitrogenous heterocyclic bases, pentose sugar (5 carbon sugar, phosphoric acid, examples, coenzymes (nad, napd, fad, genetic material (dna and rna, atp.
