Question 1: hydrocarbons

Answer:

are organic molecules consisting of only carbon and hydrogen

Question 2: antiparallel

Answer:

the two backbones run in opposite 5'? 3' directions from each other, an arrangement

Question 3: functional groups

Answer:

are the chemical groups that affect molecular function by being directly involved in chemical reactions

Question 4: hydrolysis

Answer:

a reaction that is essentially the reverse of the dehydration reaction

Question 5: quaternary

structure

Answer:

results from interactions between multiple polypeptide chains, due to all the same bonds seen in the tertiary structure.

Question 6: polar

Answer:

unbalanced due to unequal sharing electrons thus it confers a partial charge to the molecule

Question 7: polypeptides

Answer:

are unbranched polymers built from the same set of 20 amino acids

Question 8: hydrophobic

Answer:

water fearing

Question 9: denaturation

Answer:

loss of a protein's native structure

Question 10: ions

Answer:

charged particles resulting from the giving or taking of electrons

Question 11: bonding

Answer:

when two nuclei attract the same electrons

Question 12: four levels of protein structure

Answer:

? Proteins are very diverse, but have three levels of structure called primary, secondary, and tertiary structure ? A fourth level, quaternary structure, arises when a protein consists of two or more polypeptide chain

Question 13: disaccharide

Answer:

is formed when a dehydration reaction joins two monosaccharides; this covalent bond is called a glycosidic linkage

Question 14: glycogen

Answer:

is a (short term energy) storage polysaccharide in animals

Question 15: unsaturated fatty acid

Answer:

have one or more double bonds

Question 16: phospholipid,

Answer:

two fatty acids and a phosphate group are attached to glycerol

Question 17: carbohydrates

Answer:

include sugars and the polymers of sugars

Question 18: Glycerol

Answer:

a 3-carbon alcohol with a hydroxl group attached to each carbon

Question 19: double helix

Answer:

DNA molecules have two polynucleotides spiraling around an imaginary axis

Question 20: monosaccharides

Answer:

have molecular formulas that are usually multiples of CH20; glucose is the most common monosaccharide

Question 21: hydrophilic

Answer:

water loving

Question 22: chaperonins

Answer:

are protein molecules that assist the proper folding of other proteins

Question 23: hydrogen bonding

Answer:

between partial positive hydrogen and partial negative oxygen of adjacent molecule
