Document Summary

4 classes of organic molecules: carbs. Only make up 1% of body weight. Provide crucial role as substrate for energy production (atp), especially important during exercise. Certain tissues can only use carbohydrates for energy (ex. They"re also important in the extracellular matrix, the glycocalyx. Structure: oxygen and carbon ring with hydroxyl groups attached, so its polar. The three in humans are glucose, galactose, and fructose. Monosaccharides are linked together by dehydration reactions. Polysaccharides-many sugars hooked together in storage form of carbs. Starch is plant form, while glycogen is animal form: glycogen is highly branched, lipids. Make up 15% of body weight (fat) Fats are made of fatty acids; long c chain with one carboxylic acid on end; non-polar, so water insoluble. 4 lipid subclasses- fatty acid: saturated-all carbon bonds are single bonds; max. Triglyceride fats: 3 fatty acids attached to a glycerol molecule through dehydration, this is primary storage form of fat.
