    Carbohydrates 1) Monosaccharides= same formula (C6H12O6) yet slightly different structures 2) Polysaccharides a. Starch (amylose)= unbranched chain of glucose b. Glycogen= branched chain of glucose (20 min supply in muscles) both starch & glycogen are made from α (alpha) glucose, both bonds can be hydrolyzed by our bodies c. Cellulose is made from β (beta) glucose. Our bodies cannot hydrolyze cellulose: cellulose is indigestible & comes out as #2. β Glucose are H‐bonded together for added strength α Glucose does not have H‐bonds Lipids 1) Triglyceride a. Glycerol + 3 fatty acid molecule 3 carbons | each fatty acid is a long chain b. Saturated= all carbon‐carbon bonds are single (c‐c), solid at room temperature c.

    The dehydration synthesis process is the process by which all organic compounds are bonded. The dehydration synthesis process takes the hydrogen (H) of one monomer, and the hydroxyl (OH) group of the another combines them to form water. With the removal of the water molecule, the two monomers are now able to make covalent bonds with each other and share electrons. Simply, the two monomers are being dehydrated to synthesize a bigger molecule. This process takes place in an enzyme that allows the process to quickly occur and create large strings of monomers, creating poly______ of the specific macromolecule. The reversion of this process is the process called hydrolysis. This process adds water back into the monomers, forcing them to break off…
