Ch 2-Part 2 Flashcards
carbohydrates
variety of sugars, larger ones have sugar strung together in large polymers (glucose or cellulose)
lipids
do not interact well with water, largely carbon and hydrogen (cholesterol or coconut oil)
proteins
serve as enzymes in order to facilitate chemical reactions, transporters to get things across the membrane, store materials, provide structure and support for the cell (keratin or hexokinase)
nucleic acids
transmitting genetic info (DNA or RNA)
macromolecules
large molecules with complex structure
hydrolysis
method in which proteins are broken down into amino acids
dehydration synthesis
making a bond between two monomers by removing water from their structure–build polymers
Monosaccharides
simple sugars
Disaccharide
two monosaccharides together
Polysaccharide
two or more monosaccharides being joined
More on carbohydrates
common source of dietary energy for animals and important building blocks of plants, include simple sugars and larger molecules made from sugars
