Test Review Unit 1 Flashcards
Isomers
Different compounds with same molecular formula
Structural isomers
Atoms arranged in different sequences
Stereoisomers
Same sequence of molecular formula but differ in arrangement of atoms in space
Geometric isomer
Same structure but flipped
Enantiomers
Mirror image isomer
Anabolic reaction
Small molecule to big molecule
Catabolic
Macromolecules broken down into subunits
Hydrolysis
Putting water in a reaction
Condensation reaction
Water coming out
Oxidation reaction
Transfer of one or more electrons
Polypeptide chain
Many amino acids linked by peptide bonds
Peptide bond
Bond between amino acids
Globular protien
Made up of one or more polypeptide chains
Denaturatiom of protien
If PH or temperature are altered the protein may unravel and no longer works s a Protein
Protein functions
Muscle composition, hair, in cell membrane, enzymes
Nucleic acids
Store hereditary info
Pyrimidines
Cytosine, thymine, uracil
Purines
Adenine and guanine
Pentose
Deoxyribose in dna with one less oxygen than ribose for rna
Phosphate group
Attaches to number 5 carbon
Polynucleotide
Monomers joined by covalent bonds called phosphodiester bonds
Monosaccharides
Primary storage molecule and soluble in H2O
Alpha beta configuration
If OH is below OH and if OH is above its Beta
Oligiosaccharides
2 or 3 monosaccharides are linked
2 or 3 monosaccharides linked
Glycosidic linkage
Glucose+glucose
=maltose
Glucose+fructose
=sucrose
Glucose+galactose
=lactose
Starch
Main energy storage in plants
Glycogen
Animals store glucose as glycogen
Cellulose
Major component in cell walls also known as fiber
Why glucose forms a ring structure
Ring makes it safer to transfer
Lipides amount of energy given
Double the amount of carbs
Lipides Major component of what
Cell membranes
Fats
Glycerol+fatty acids= triglyceride
Carboxyl and hydroxyl reaction uses what bond
Ester linkage
Saturated fats
Maximum amount of hydrogen
Only single bonds
Solid room temperature
Unsaturated fats
Lowest amount of hydrogen
Has double bonds
Liquid at room temp
Phospholipids
Forms cell membranes
Tail hydrophobic
Head hydrophilic
Steroids/sterols
Contains 4 fused hydrocarbon rings
Cholesterol Found in blood
Waxes
Hydrophobic so good to be used as water proof coating
