BIOL 101 Lecture Notes - Lecture 6: Nutrasweet, Aspartame, Colorectal Cancer
Document Summary
Organization of life: cellular level a. i. 1. Nucleic acids: only produced by us, genetic material, dna. Not all carbohydrates are digestible: chitin, cellulose. Non-polar molecules that do not dissolve in water. Fats are tasty molecules too plentiful in our diets. Each carbon in the hydrocarbon chain is bound to two hydrogen atoms. *saturated fatty acids have more hydrogen atoms than unsaturated fatty acids, which is why they exist as a solid at room temperature. At least one carbon in the hydrocarbon chain is bound to just one hydrogen. Can attach to vessel walls and cause them to thicken, which may lead to high blood pressure, stroke, and heart attack. 90% of circulating cholesterol is produced by our liver from saturated fats. Ldl (bad one) carries cholesterol to body tissue. Hdl (good one) carries cholesterol away from tissues to liver for disposal. Regulate sexual development, maturation and sex cell production. Proteins are versatile macromolecules that serve as building blocks.
