Biochemistry of Molecules Flashcards
What is the name for two or more molecules that contain the same number and type of atoms but have different structures/projections?
Isomerism.
Structural isomers have what?
The same molecular formula, different structure.
What 3 ways may isomers differ structurally?
- Chain - edits to number of carbon atoms present.
- Position
- Functional groups
Stereoisomers have what?
The same molecular formula and structure but different arrangements (3D shape difffers).
A geometric change in stereoisomers means what?
Same number of atoms and fundamental layout.
Present in Cis or Trans formation.
An optical change in stereoisomers means what?
Same chemical structure but cannot be super-imposed (will not match up when placed ontop of each other as they are mirror images).
What 3 atoms are carbohydrates composed of?
C = Carbon H = Hydrogen O = Oxygen
Monosaccharide =
1 carbohydrate/molecule.
Oligosaccharide =
3-10 carbohydrates/molecules.
What reaction combines two monosaccharides to form a disaccharide?
Condensation.
What bond is formed when a condensation reaction has occurred, forming a disaccharide.
Glycosidic.
Are lipids polar or non-polar?
Non-polar, making them soluble in water.
What components make up a triglyceride?
AKA TRIGS/TAGS
Glycerol backbone.
3 fatty acids.
Fatty acids bond to a glycerol molecule via what reaction?
Condensation.
Unsaturated fats contain what type of bonds between carbon molecules?
Double bonds
C = C
