B1.1 Carbohydrates and Lipids Flashcards
Macromolecules
Large molecules: carbohydrates, lipids, proteins, nucleic acids
Polymer
Chains composed of monomers
Polymersion
Reaction which joins monomers, forming polymers
Condensation reaction
Reaction which joins substances, producing H20 as a byproduct
Hydrolysis reaction
Reaction which separates substances by adding H20
Glycosidic bond
Bond between a sugar and another substance (or another sugar)
1-4 bond
Linear bond
1-6 bond
Branched bond
Monosaccharides
2+ bonded sugars. Classified by the number of carbons present.
ABBA
Alpha below, Beta above -> orientation of hydroxyl (OH) group determines whether glucose molecule is beta or alpha.
Starch
A type of monosaccharide which stores energy as glucose in plants -> amylose or amylopectin
Amylose
Linear structure made up of glycosidic 1-4 bonds, highly coiled for compact energy storage
Amylopectin
Highly branched structure made up of glycosidic 1-4 Aplha linear backbone, and branching 1-6 Aplha bonds, highly coiled for compact energy storage
Glycogen
Stores energy in animals, linear backbone composed of glycosidic 1-4 bonds with occasional 1-6 bond branching off.
Cellulose
Makes up the cell wall, contains alternating beta-glucose bonds
Glycoprotein
Protein with a carb attached -> cell-to-cell recognition, receptors, structural support
Lipids
Non-polar & hydrophobic - energy reserves
Sterioids
Have 4 carbon ring structure
Triglyceride
LIPID: 1 glycerol, 3 fatty acids, joined by ester bonds
Phosopholipid
LIPID: 1glycerol, 2 fatty acids, 1 phosphorus, joined by ester bonds
Saturated fatty acids
Linear structure, no double bonds, solid at room temperature
Unsaturated fatty acids
Kinky structure (caused by double bond), 1+ double bonds, liquid at room temperature
Trans fats
H atoms are opposite (trans), considered unhealthy & are artificially produced
Cis fats
H atoms are on the same side, considered healthy & are found naturally
