science Flashcards
The building blocks are called
Monomers
Monomers of carbohydrates
Monosaccharides
Monomers of proteins
amino acids
monomers of nucleic acids
Nucleotide
What components make up a lipid molecule
3 carbon Glycerol molecules + 3 fatty acid chains
How do animals store glucose
glycogen
How do plants store glucose
starch
forms plant cell walls
Cellulose
forms the exoskeleton of insects and cretures
chitin
4 biomolecules of life
Nucleic Acids
Proteins
carbohydrates
Lipids
Function of carbohydrate
Short term enegry source
Function of Lipid
Long-term energy source, insulation, protection padding, cell membrane
Function of Nucleic Acids
store genetic information
responsible fore protein synthesis
Function of Proteins
Overall structure of body
Nucleic Acids are composed of
DNA
RNA
DNA function
store genetic information
RNA function
protein synthesis
Carbohydrates composed of
Monosaccharides
Disaccharides
Polysaccharides
4 types of lipids
triglycerides
phospholipids
steriods
waxes
dehydration synthesis
A water molecule is released
creates polysaccharides
hydrolysis
Water molocule is gained
carbohydrate examples
maltose,sucrose,lactose
Sugar ends in
OSE
Saturated fats
bonds?
RT?
example?
Single bonds
solid at room tempature
butter,lard,animal fat
Unsaturated Fats
bonds?
RT?
example?
Double Bonds
Liquid at room tempature
Olive oil, corn oil, plant oil
Fats are what biomolecule
Lipids
Triglycerides made up of
glyceride and 3 fatty acid chains
phospholipids are made up of
glycerol
two fattu acids
phosphate group
Steriods are made up of
4 carbon rings
All lipids are
insoluble
ATP function
source of energy the cell uses to do cellular work
ATP is composed of
Nitrogenous Base
Adenine
Rihose
DNA function
Stores genetic information
RNA function
Involved in protein synthesis
Chemical formula for glucose
C6H12O6
Simple sugars are
monosaccharides and disacharides
Complex sugars are
polysaccharides
2 monosaccharides is
disaccharide
many monosaccharides are
polysaccharides
How many amino acids are there
20
What gives each amino acid its chemical properties “R” group
based on the amino group
Peptide bonds
Bonds between amino acids
