Macromolecule Test Flashcards
1:2:1 ratio of C:H:O
Carbohydrates
Adenine
A type of nitrogen containing base in both DNA and RNA.
Amino Acid
Carbon compound joined by peptide bonds; building block of proteins.
Carbohydrate
Organic compound containing carbon, hydrogen, and oxygen in a ratio of one oxygen and two hydrogen atoms for each carbon atom.
Cellulose
An insoluble substance which is the main constituent of plant cell walls and of vegetable fibers such as cotton. It is a polysaccharide consisting of chains of glucose monomers.
Chitin
Tough, flexible polysaccharide in the exoskeletons of insects and crustaceans and in fungal cell walls.
Cytosine
A type of nitrogen containing base in both DNA and RNA.
Dehydration Synthesis
A chemical reaction in which a water molecule is removed to complete the reaction.
Deoxyribonucleic Acid
DNA: contains the instructions needed for an organism to develop, survive and reproduce. Make up of DNA is random but the nucleotide pairs have to stay together and can’t mix.
Deoxyribose
A sugar contained in DNA with one less oxygen atom than Ribose.
Dipeptide
An amino acid chain linked by peptide bonds but with just two peptide bonds.
Disaccharide
A carbohydrate with two monosaccharides chemically bonded together.
Double Stranded
Twisted-ladder shape of DNA, formed by two nucleotide strands twisted around each other.
Enzyme
A protein that speeds up a biological reaction.
Fatty Acid
The building blocks of the fat in our bodies and in the food we eat.
Fructose
A type of carbohydrate that makes fruit sweet.
Galactose
A monosaccharide with the same chemical equation as glucose but differs in the position of one hydroxyl group.
Glucose
A monosaccharide.
Glycerol
A carbohydrate that is used to link lipids.
Glycogen
The stored form of glucose that’s made up of many connected glucose molecules.
