BIOCHEMISTRY The study of organic compounds

ORGANIC COMPOUNDS Compounds that contain carbon. Except carbon dioxide-CO 2 C

POLYMER A giant molecule made of many smaller molecules (monomers).

CARBOHYDRATES Sugars Used for energy. Contain C, H, O in a 1:2:1 ratio. Types: Monosaccharide Disaccharides Polysacchari des

LIPIDS Fats, waxes and oils Fatty acids & Glycerol Contain C, H, and O, but not in a 1:2:1 ratio. Used to store energy. Insulation Repel water Phospholipids (membranes)

Structure of a lipid

Saturated vs. unsaturated fats

Carbohydrates True or False Carbohydrates are polymers made up of smaller subunits called Monosaccharides

Carbohydrates True or False Carbohydrates contain C, H, and O, and they are the body’s first source of energy.

Lipids True or false The structure of a lipid resembles the letter “Z”

Lipids True or False? The Monomer of a lipid contains 1 fatty acid and 3 glycerol chains and is the body’s prime source of energy.

PROTEIN Polymers made of amino acids (20). Contain C, H, O and N. Functions: Build & repair tissue. Movement Structure Transport Defense Regulation (Hormones & Enzymes)

Shape matters! Enzymes are proteins that have an active site some where on the molecule where others molecules can land and react

NUCLEIC ACIDS Made of nucleotides: sugar + a nitrogenous base + a phosphate group. Contain C, H, O, N & P Contain genetic information. Control the activities of cells. DNA & RNA

Nitrogen Bases have a ring structure

What is it? Based on the chart above, food sample D is most likely to be A. orange juice B. pasta C. butter D. scrambled eggs Based on the chart, Steak could most likely be found in A. food sample A B. food sample B C. food sample C D. food sample D

Protein True/False Proteins are composed of Amino Acids linked together, similar to a string of beads.

Proteins True or False? Proteins have several functions in the body, including structure and regulation.

Nucleic acids True or False? The structure of DNA is often called a triple Helix

Nucleic acids True or False? Nucleic acids are large polymers composed of smaller units called nucleotides
