Building Blocks Flashcards
(38 cards)
Monosaccharides
Single sugars, the building blocks
Carbohydrates
C6H12O6; used in energy storage
Glucose
6C sugar, used for energy, “ blood sugar” (C6H12O6…. has an aldehyde and hydroxyl group)
Fructose
6 carbon sugar, used for energy “ fruit sugar” ( C6H12O6…has hydroxyl and ketone group)
Galactose
6carbon sugar, from lactose digestion
Ribose
5 carbon sugar; found in RNA and ATP
Deoxyribose
5 carbon sugar; found in DNA
Disaccharide
Double sugars; ether linkage between sugars
Sucrose
Table sugar; glucose + fructose
Maltose
From starch digestion; glucose + glucose
Lactose
Milk sugar; glucose + galactose
Polysaccharides
Many sugars
Glycogen
“Animal Starch” chain of glucose- we can break down
Starch
Plant origin-chain of glucose- we can break down
Cellulose
Cell wall in plants and algae(except blue green ), chain of glucose- we can’t break down.
Lipids
C,H, and very few O
Triglycerides/fats
Glycerol + 3 fatty acids ( building blocks) used for energy/ energy storage
Glycerol
Has 3 hydroxyl groups
Fatty acids
Has carboxyl group on end and carbon chain( hydrophobic)
Phospholipid
Glycerol + 2 fatty acids + phosphate ( building blocks)
Used for cell membrane and organelle membrane structures in cells (C,H,O,P) * create phospholipid bilayer*
Steroids/sterol
4 ring structure
Cholesterol
Strengthens cell membranes in animal cells
Ergosterol
Strengthens cell membranes in fungal cells
Structures
Primary structure= actual chain of AA; bonds are strong
Secondary structure= coiling of AA; done by H- bonds that are weak
Tertiary= Distinct 3D shape driven by AA sequence so bonds are variable, some H, some S but they are weak.
