Unformatted text preview: Protein A. Amino Acids- monomers a. 20 different kinds i. 8 that are left over are essential amino acids from diet b. Peptide Bonds- connects amino acids into proteins c. Size- proteins are gigantic in comparison to amino acids 1. Properties d. variations: total number sub-groups & sequence of amino acids i. order- wont be 1, 2, 3, 4, 5 2. Types a. Simple proteins- made up only of amino acids b. Examples i. Albumin-found in blood plasma ii. Insulin- hormone and responsible for blood glucose levels (controls) iii. Actin & Myosin (work together)- required for muscle contraction B. Conjugated- prosthetic group (chemical not containing amino acids) combined with simple proteins a. Examples: i. Hemoglobin (found in red blood cells) 1. HEME + GLOBIN(protein) ii. Glycoproteins: simple protein + oligosaccharide 1. Antibodies found in blood 2. In all membranes 3. Fibrinogen- blood clotting protein 4. Surface red blood cells a. Blood groups 5. Lipoproteins - protein +cholesterol a. LDL - low density lipoprotein i. takes old cholesterol from tissues & adds...
