Carbohydrates Nucleic Acids and DNA Amino Acids, Proteins, and Enzymes Lipids*sorry guys…lots of writing today

Write down and try to answer the following questions: (there will be 4)

1. The DNA in our genes codes for:a. amino acid sequences for many proteinsb. base pair sequences for lipid storagec. carbohydrate sequencesd. none of the above

2. Which best highlights the main difference between carbohydrates and proteins?

a. Carbohydrates are organic and proteins are inorganic

b. Proteins are polymers and carbohydrates are monomers

c. Proteins are monomers and carbohydrates are polymers

d. Proteins are made of amino acids and carbohydrates are made of sugars

3. Which pair of substances includes two lipids?a. steroids, sucroseb. sucrase, detergentc. detergent, steroidsd. oil, valinee. wax, sucrase

4. What do all amino acids have in common?a. they are all inorganicb. they contain an amine group and a carboxyl groupc. they are all present in the structure of RNAd. they all have the same R chain, allowing them to form bonds with one another

The key to metabolism (the break down of food into sugar for energy).

Names end in –ose. Monosaccharides: single monomer of carbon, hydrogen and oxygen in a 1:2:1 ratio

Polysaccharides: linked monomers; found in starches and cellulose

Enzymes lower activation energy needed for reaction to happenEx. sucrase aids the hydrolysis of sucrose into glucose and fructose

sucrase

Cellulose is basically the same as starch, but the alpha linkage here is beta in cellulose (diagonal-ish). Cellulose can’t be digested because we lack the enzyme to break beta linkages between sugarmonomers.

•Folded strands made of amino acids linked together through peptide bonds. They gain their function from the way they fold.•20 different types of amino acids

(letters combine to make numerous sequences (words). AA’s strongly influence how proteins fold depending on their polarity and hydrophobic regions•Amino acids have a repeating

structure (one amine group, one carboxylic acid group, one hydrogen atom) with a variable side chain (R).

o R groups range from a simple hydrogen side chain to complicated chains like tryptophan.oIn the cell ribosomes, amino acids are combined together (based on the RNA sequence) to make protein sequenceso two H’s of the amine group and one O of the carboxylic acid group make H2O. A peptide bond forms !!!

Codons

Amino Acids (AA formed by 3 letter mRNA

codons)

polymers that serve as a blueprint for proteins

two types: Deoxyribonucleic acid (DNA) and Ribonucleic Acid (RNA).

backbone is made of sugar and phosphates

nucleotides (monomers) from one strand pair up with monomers from the other strand

four nitrogenous bases: adenine, guanine, cytosine and thymine.

each base can only pair with one other base via hydrogen bonding: A with T, C with G

allows the DNA to replicate with few errors

large, structurally diverse group of naturally occurring organic compoundssoluble in nonpolar organic solvents (ex. ether, chloroform, acetone, benzene)insoluble in water

one of the major food groups of our diet. Fats: solid or semisolid at room temperature; found in animalsOils: liquid; originate chiefly in plants and fish

Fats and Oils: “triglycerides”-triesters of fatty acids (long carboxylic acids) with glycerol - biofuel is composed of random, single fatty acids

Waxes: esters of fatty acids usually with one hydroxyl group.

beeswax

CH3(CH2)24CO2-(CH2)29CH3

Terpenes: complicated pentane polymers; natural byproducts of plant metabolism

Steroids

main constituents of cell membranesester or amide derivatives of glycerol with fatty acids and phosphoric acid.

Phospolipids

Soaps and Detergents: 8+ carbons chains (hydrophobic) that exhibit unusual behavior in water due to the presence of carboxylic acid and salt regions (hydrophillic)

Oil Refiningbreaking down polymers or making polymers larger

Polymer Chemistry

oil refined to produce pure polymers

polymers are converted into gasoline, plastics, rubber, or pharmaceutical precursors
