Biochemistry Flashcards
Define biochemistry
the study of molecules that make up living things
define organic
molecules that contain carbon
define adhesion
water attracting to another substance through hydrogen bonding
define cohesion
water attracting to more water through hydrogen bonding
define specific heat
water’s ability to maintain a stable temperature for a long time
define carbon
element that makes up diverse organic molecules
define covalent bond
bond in which electrons are shared
define hydrogen bond
weak bond between molecules
define molecules
two or more atoms bonded together
define atom
combine to form molecules
define proton
positively charged sub atomic particles
define nuetron
nuetral sub atomic particle
define electron
negitevly charged sub atomic particles
define valence shell
outer electron shell, involved in chemical bonding
define lipid
biological molecule class that includes fats, waxes, oils, and some hormones
define carbohydrates
biological molecules class that includes sugars, starches, and structural molecules
define protein
biological molecule class that includes enzymes, transport molecules, and some hormones
define nucleic acid
biological molecule class that includes RNA and DNA
define DNA
molecule responsible for storing genetic information
define nucleotide
monomer of nucleic acid, includes phosphate, sugar, and nitro geneous base
define amino acid
monomer of protein
define monosaccharide
monomer of carbohydrates
define polysaccharide
starch, glycogen, cellulose
define disaccharide
two monosaccharides bound together
define iodine
indicator when starch turns black or purple when positive
define starch
polysaccharide used for energy storage in plants
define glucose
most common monosaccharide
define glycogen
polysaccharide used for energy storage in animals
define insulation
functions of lipids especially in mammals
define short term energy
functions of carbohydrates
define phospholipid
used to make up cells membranes
define insulin
protein hormone used to regulate blood sugar
define enzyme
protein used for metabolism and other functions
define hemoglobin
protein responsible for transporting oxygen in the body
define indicator
chemical that change color in the presence of a molecule
define cellulose
polysaccharide used to build cell walls in plants
define chitin
polysaccharide used to build exoskeletons in insects
-ose
signifies the name of a carbohydrate
define polar
molecule with partial charge because of unequal electrons sharing . mixes with water
define nonpolar
no partial charge because electrons are shared equally. Does not mix with water
