b) Lipids (cont’d)(14) Triglycerides- made of glycerol and 3 pamitic acidsFat storage – largest form of energy reserve!transported to the hypodermis and around soft organs like the greater omentumfound in adipose tissuto determine the Triglyceride amount in body:Girth measurements- measure neck, arm and abdomen  18% errorBMI- bodily mass index by weight divided by height – extremely flawedBioelectrical impedence – scale that sends an electric shock through your body and measures depending on how fast it goesHydrostatic Weight- measured by displacement of water to get water density (1% accuracy)Bod pod- measured by displacement of air to get densityDEXA- best method separates solid mass from fat and can measure the amount of fat (less than 0.1% error)Nutrition for LipidsAmounts – 15-20% of Total nutrient. Polyunsaturated should be 90% of ingested fatsSourcesVegetable – Corn, Olive, Canola, Nuts, Seeds. Unsaturated FatsDairy – Saturated and Unsaturated FatLean Meats – Fish, Chicken, Turkey. Saturated and Unsaturated FatsRed Meats – Beef, Pork, Venison. Saturated FatsObesity is the source of many pathological issues: Gall stones, kidney failure, cancer, diabetes, arthritis, stroke/heart attack, hypertension, etc.Nucleic AcidsBuilding blocks are nucleotides:Nitrogenous base- 2 types purine (adenine and guanine) and pyrimidine (cytosine, uricil and thymine)sugar- dexoxyribose or ribosephosphate chain of one, two or threeinformation and energy moleculesNucleotide use:single- Energy in the form of ATP and Internal Signals in the form of cyclic AMPbonded- Information molecule (info stored in base) and Energy (stored in phosphates)DNA- transferred, inheritable materialonly 2 times is DNA vulnerable and unzipped- transcription and translationDNA—transcribed mRNA—translated tRNAtRNA- brings amino acids to make proteins, rRNA are the most abundant nucleic acid found in the nucleosomeBiological uses: info storage info use  Protein formationBY 116 1st Edition Lecture 3Outline of Last Lecture V.
