Proteins, lipids, carbohydrates & more. Organic compounds Proteins, lipids, carbohydrates & more.

Hydrocarbon textbookofbacteriology.net Chain of carbon atoms bonded to H atoms that is the backbone of many organic cmpds. Functional group – atoms or molecules attached to the skeleton that make it chemically unique

Polymers Large molecules made up of smaller repeating parts. Monomer – single repeating unit; a building block Assembled through synthesis rxns

Carbohydrates Contain C,H, & O Sugar, glycogen, starch & cellulose 2-3% of body mass Main function is as energy source for ATP production Contain 1 H2O per C

Monosaccharides Simple sugars that have 3-7 C atoms Used to build larger carbohydrates

Disaccharides Simple sugars formed from the combination of 2 monosaccharides by dehydration synthesis. Sucrose & lactose are examples

Polysaccharides Made from 10-100’s of monosaccharides thru dehydration synthesis. Glycogen, starch & cellulose are examples Broken down into glucose by hydrolysis

Lipids Lip- means fat 18-25% of body mass Contain C, H & O Fewer O than carbs so fewer polar covalent bonds. Thus insoluble in water (hydrophobic) Have to connect to a hydrophilic protein to “dissolve” in blood. This makes a lipoprotein.

Fatty acids Simplest of lipids Used to make other lipids Can be catabolized to make ATP Saturated – filled with single bonds Un saturated – has double bonds aafp.org

Triglyceride Most concentrated form of chemical energy Made of 1 glycerol w/ 3 fatty acids attached Fats- solid at room temp, mostly saturated Oil- liquids at room temp, mostly unsaturated Insulation, protection & energy storage

Phospholipids uic.edu Same triglycerides except there’s a phosphate group in place of a fatty acid Have a polar end that is hydrophilic Make up cell membranes fz-juelich.de

Steriods Made of 4 carbon rings Synthesized from cholesterol Used in digestion of lipids, cell membranes, regulate sexual functions & blood sugar levels. redzuannorazlan.blogspot.com
