four major organic substances

carbohydrates, lipids, proteins, nucleic acids

function group, temp unattached, highly reactive

primary source of energy needed by cells critically for RNA and DNA

three types of carbohydrates

monosaccharides disaccharides polysaccharides

main example (glucose) simple sugars

two or more simple sugars bonded through dehydration synthesis ex.) sucrose, maltose, lactose

polymer of monosaccharides, dehydration synthesis ex.) glycogen

water-insoluble, nonpolar (no specific charge) serve a structural role, used for energy purposes, protects vital organs(fat pads) , can help speed nerve impulses up

triglycerides, phospholipids, steroids, prostaglandins

most abundant lipid, body's most concentrated source of energy, glycerol and fatty acids needed to build a fat molecule

saturated fatty acids

all hydrocarbon chain bonds are filled or saturated w hydrogen atoms, no double bonds. think animal fats (no kinks due to no bonds, allows for molecules to tightly fit together forming that solid mass at higher temperatures)

two fatty acids and one phosphorus. the phosphorous side is polar, water-soluble &, hydrophiblic. the fatty acid side is nonpolar, and hydrophobic. can word bilayers in waterwith fatty tails facing one another

surrounds every body cell, stabilizes cellular structure, used to make bile salts needed for digestion.

free radical	function group, temp unattached, highly reactive
carbohydrates	primary source of energy needed by cells critically for RNA and DNA
three types of carbohydrates	monosaccharides disaccharides polysaccharides
monosarrharies	main example (glucose) simple sugars
disaccharides	two or more simple sugars bonded through dehydration synthesis ex.) sucrose, maltose, lactose
polysaccharides	polymer of monosaccharides, dehydration synthesis ex.) glycogen
Lipids	water-insoluble, nonpolar (no specific charge) serve a structural role, used for energy purposes, protects vital organs(fat pads) , can help speed nerve impulses up
Types of lipids	triglycerides, phospholipids, steroids, prostaglandins
triglycerides	most abundant lipid, body's most concentrated source of energy, glycerol and fatty acids needed to build a fat molecule
saturated fatty acids	all hydrocarbon chain bonds are filled or saturated w hydrogen atoms, no double bonds. think animal fats (no kinks due to no bonds, allows for molecules to tightly fit together forming that solid mass at higher temperatures)
phospholipids	two fatty acids and one phosphorus. the phosphorous side is polar, water-soluble &, hydrophiblic. the fatty acid side is nonpolar, and hydrophobic. can word bilayers in waterwith fatty tails facing one another
cholesterol	surrounds every body cell, stabilizes cellular structure, used to make bile salts needed for digestion.
