Topic One: Carbon Flashcards
Isomers
Molecules that have the same modules formula but differ in arrangement of atoms= in molecule that are very different in biological activity
Carbon is unparalleled in ability to form molecules that are large, complex, and diverse. Why?
1) four valence electrons
2) up to four bonds
3) single- triple covalent bonds
4) form large molecules
5) molecules can be chains, rings gaped, or branch
Polymers
Long chain molecules made up of monomers. Example, proteins=amino acids monomers
Dehydration reaction
Create polymers form of monomers, two monomers are joined by removing one molecule of water
Hydrolysis
H2O added to split large molecule occurs in reverse of dehydration reaction
Carbohydrates
Polymer such as starch are made from these and etc. subunits, all carbohydrates exist in the ratio of one carbon to two hydrogens to one oxygen such as CH20
Monosaccharides
Monomers of carbohydrates, 1 to 2 to 1 ratio such as glucose C6H1206 and ribose C5H10O5
Polysaccharide
Polymers of monosaccharides such as starch cellulose and glycogen
Function of polysaccharides
Energy storage (monosaccharides) and structural support (polysaccharide)
What are lipids?
Diverse groups of hydrophobic molecules that are not polymers
Fatty acids
Hydrocarbon chains of variable lengths, it is nonpolar and hydrophobic
Fats
Triglycerides and are made up of glycerone and three fatty acid molecules
Saturated fatty acids
Have no double bonds between carbon, tends to pack solid at room temperature, leads to cardiovascular disease, commonly produced by animals such as butter and lard
Unsaturated fatty acids
Have a carbon double bond which means kinks, tends to be liquid at room temperature, and are commonly produced by plants such as oil
What are the functions of lipids?
It’s stores energy 12 times the calories than carbon storage, Protech’s vital organs, provides insulation, and is stored in adipose cells
