Document Summary
Chapter 15: carbohydrates biomolecule: organic but bigger and more complex than what you"ve seen before, organic functional groups ionic portions-organic and inorganic all parts help to modulate function. One dalton (d, da) is the mass of one hydrogen atom, 1. 66x10-24 g. The four major categories of biomolecules: carbohydrates 2. lipids 3. proteins 4. nucleic acids. C6h12o6 + 6o2 (photosynthesis) carbohydrate- organic molecules of the formula cn(h2o)n: generally polyhydroxy aldehydes and ketones, also includes carbohydrate derivatives- modified with other functional groups, sugar aldehyde sugar- aldose ketone sugar- ketose. Monosaccharides that you need to know: aldohexose, a. k. a. dextrose, the nearly exclusive fuel source for your brain, provided in diet from starch, lactose, maltose, and sucrose. Important in cellular membranes of the brain and nervous system: provided in diet by lactose-containing dairy foods, galactosemia, a condition when the enzyme to convert galactose to glucose is missing.
