Biomolecules Flashcards
Biomolecules
Compounds found in living organisms
Carbon
All biomolecules contain a Carbon chain
Backbone of biomolecules
Carbon
Monomers
building blocks
Polymers
multiple monomers
Dehydration synthesis
monomers to polymers
Hydrolysis
polymers to monomers
Carbohydrates
short term energy
Monosaccharide
simple sugars
Types of monosaccharide
Glucose, fructose, galactose
Disaccharide
double sugar
Glycosidic bond
bonds two monosaccharides
glucose + fructose
sucrose
glucose + glucose
maltose
glucose + galactose
lactose
Polysaccharide
complex carbohydrates
Starch
energy storage of plants
Glycogen
energy storage in animals/fungi/bacteria
Chitin
cell wall in fungi, exoskeletons, fish scales
Lipids
long term energy storage
Monomer of lipids
techenically none, but fatty acid chain ig :P
Types of lipids
Fatty acids, Triglycerides, Phospholipid, Steroids, Waxes
Saturated Fats
solid at room temp; no double bond; straight
Unsaturated
liquid at room temp; double bond in fatty acid chain; curved
Polyunsaturated fats
has two or more double bonds in the carbon chain; omega vitamins
Triglycerides
3 fatty acids attached to glycerol (mukhang intergrated circuit)
Phospholipid
Hydrophilic head and hydrophobic tail
Steroids
Cholesterol and Hormones
Proteins
Basis for the major structural components of animal and human tissues
Most abundant macromolecule
protein
Amino acid
monomer of protein
Nucleic Acids
DNA and RNA
DNA
double helix strand
RNA
single strand
Nitrogenous base
adenine guanine, thymine, cytosine, uracil
