III. Nucleotide Structure (3 major parts) DNAVsRNA 1. Phosphate 2. Deoxyribose (Sugar) 2. Ribose 3. Nitrogenous Bases (4) 3. No Thymine Adenine (A)“ Guanine (G)“ Cytosine (C)“ Thymine (T)Uracil (U)
10
DNA is a polymer (long chain) of nucleotides (Phosphate, Sugar Base)
11
DNA looks like a twisted ladder – is referred to as a: “double helix”
12

IV. Proteins Contain SPONCH – Sulfur only sometimes Most proteins end in “in” (seratonin, hemoglobin, tubulin, actin, myosin………) Major types of Proteins: Antibodies Enzymes Muscles Hormones Pigment
14
V. Protein Structure Functional Groups (found in _______ ______) Amino Group (NH 2 ) Carboxyl Group (_______) R-Group (_______between amino acids)
15
V. Protein Structure Functional Groups (found in amino acids) Amino Group (NH 2 ) Carboxyl Group (COOH) R-Group (Varies between amino acids)
16
Amino Acids are the subunits of proteins!
17
Many times amino acids are abbreviated with three letters! Threonine (Thr) Amino Acids can be polar,
18
acidic, basic,
19
or nonpolar A.A. are dissolved in water in living things:

Level 2: ____________ Structure
28
Level 2: Secondary Structure Hydrogens (H) of one amino acid bond with Oxygens (O) of an adjacent amino acid.
29
Level 2: Secondary Structure Hydrogens (H) of one amino acid bond with Oxygens (O) of an adjacent amino acid. Results in two shapes: alpha helix (helical) and the beta pleated sheet (zig-zag pattern).

Level 3: ________ Structure
33
Level 3: Tertiary Structure “R” groups of amino acids interact and form bonds. Causes “bunching” of the alpha helix and beta pleated sheet.
34
Level 3: Tertiary Structure “R” groups of amino acids interact and form bonds. Causes “bunching” of the alpha helix and beta pleated sheet. **All proteins reach at least this level!!
