What are carbohydrates

Front

made of C, H, O -monosaccharides -simple or single sugars -disaccharides -2 linked monosaccharides -polysaccharides- long chain of monosaccharides

Back

bond (molecule or formula unit)

Front

Covalent bonds - formed by atom molecules sharing 1-3 pairs of their valence electrons

Back

Organic Molecule Synthesis

Front

Carbohydrates -Glucose, Lipids -oil and fat, Proteins -silk, Nucleic Acids DNA

Back

acid

Front

any molecule that releases a H ion - carboxyl group and ammonium

Back

exergonic reaction

Front

bond being broken has more energy ex. heat

Back

Catabolic Reaction

Front

chemical bonds are broken in the process

Back

element

Front

can't be split into simple substance

Back

number of neutrons

Front

mass number -atomic number

Back

matter

Front

anything that occupies space and has mass

Back

Steriods

Front

lipid molecules that have 4 rings of carbon atoms -sex hormones -Bile salts -some vitamins -Cholesterol

Back

base

Front

molecule that will bind to a H ion or release a hydroxide -OH -into a solution

Back

polar covalent

Front

sharing of electrons is unequal ex. C AND H

Back

Laws of Thermodynamic

Front

the amount of energy present at the beginning and end of a chemical reaction: energy can not be created or destroyed

Back

endergonic reaction

Front

requires energy usually from a molecule called ATP forms amino acids

Back

atomic mass

Front

bottom number

Back

molecule

Front

two or more atoms share electrons

Back

atom

Front

units of matter for elements

Back

cohension and adhension

Front

-molecules stick to identical molecules -molecules stick to other molecules

Back

Lipids

Front

hydrophobic -hate water -oil and fat Functions -energy storage -waterproofing -membranes in cells -hormones

Back

structure of a typical atom

Front

consist of nucleus have protons +, neutrons, electrons - shells 1st-2 2nd-8 3rd-18 electrons=protons

Back

compound

Front

substance that can be broken down into two or more different elements

Back

nonpolar convalent

Front

share electrons equally ex. H and H

Back

isotopes

Front

atoms with the numbers of protons, but different numbers of neutrons

Back

energy

Front

the capacity to do work

Back

Kinetic energy

Front

energy matter in motion

Back

potential energy

Front

energy stored by matter

Back

reversible reaction

Front

end products can revert to the original combining molecules ab=a+b or a+b=ab

Back

Four levels of structure

Front

Primary s-amino acids linked together in protein Second S- helices and pleated sheets Tertiary S-complex foldingof the protein chains Quaternary S- multiple protein chains are linked together

Back

bond (molecule or formula unit)

Front

hydrogen bond - 2 atoms associated w/ a hydrogen atom - they are weak and can't bind atoms int molecules link between molecules

Back

exchange reaction

Front

the exchange of one atom to other atoms ex. NaOH + HCL = NaCL +H2O

Back

weight

Front

the force of gravity acting on a mass

Back

buffer

Front

chemical or comb or chemicals that change the ph

Back

mass

Front

the amount of matter a substance contains

Back

Proteins functions

Front

structure - skin, hair, nails movement - actin and myosin muscles defense-antibodies in bloodstream storage - albumin in egg whites signaling - growth hormone in bloodstream Catalyzing reaction- enzymes

Back

ionic bonds

Front

ions having opposite charges ex. soduim chloride

Back

DNA AND RNA

Front

deoxyribonucleic acid found in chromosomes ribonucleic acid copies of dna used in protein construction

Back

protons and eletrons

Front

atomic number

Back

chemical energy

Front

potential energy stored in the bonds of compounds or molecules

Back

How does hydrogen bonding contribute to cohesive and adhensive properties of water?

Front

Hydrogen of one water molecule attracted to oxygen atom of neighboring molecule establishes cohesion and adhension

Back

atomic number

Front

top number

Back

Anabolic reaction

Front

bonds are formed

Back
