Biomolecules pg. 27 Biomolecules Organic = = macromolecules big(macro) molecules containing carbon, that are found in living things. contains carbon!

Monomer - Polymer - A simple molecule Complex molecule made up of many small, repeating units.

Isomers - compounds that have the same chemical formula, but different structures. Ex.Glucose = C 6 H 12 O 6 Fructose = C 6 H 12 O 6

Carbohydrates Carbohydrate - a biomolecule composed of carbon, hydrogen and oxygen. (1:2:1 ratio)

Carbohydrates 1. Monosaccharide = 1 sugar ex. glucose or fructose 2. Disaccharide = 2 sugars combined. ex. Sucrose (table sugar) 3. Polysaccharide = many sugars combined. ex. Starch, glycogen, cellulose.

Carbohydrates Functions:1. Short term energy storage 2. Give structure and support to plant cells.

Build a Carbohydrate!

You don’t need to copy this – just look at to make your model

If you are on the left side of the table – you make glucose If you are on the right side of the table – you make fructose If you are alone – find a partner.

Remove O-H from glucose and H from fructose. Bond them together to make water. Attach glucose and fructose together where you removed the H-O-H

Lipids Lipids - Large biomolecules made mostly of carbon and hydrogen with a small amount of oxygen. ex. Fats, oils, waxes and steroids

Lipids 1. Saturated fats – all carbons have single bonds ex. meat fat, chocolate, coconut oil, butter, cheese 2. Unsaturated fats – 1 double bond ex. Avacados, peanut oil 3. Polyunsaturated fats – more than 1 double bond ex. Vegetable oils

Lipids Function- 1. Cells store long-term energy as lipids (fats) 2. Insulate living organisms. 3. Forms cell membranes.

Draw the lipid

 DO NOT HAVE TO WRITE!!  Trans fatty acids are manufactured fats created during a process called hydrogenation, which is aimed at stabilizing polyunsaturated oils to prevent them from becoming rancid and to keep them solid at room temperature. They may be particularly dangerous for the heart and may pose a risk for certain cancers. Hydrogenated fats are used in stick margarine, fast foods, commercial baked goods (donuts, cookies, crackers), processed foods, and fried foods.

Proteins/Nucleic Acids Protein - a large complex polymer composed of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur. -We get protein from meat, beans and nuts

Proteins amino acids - The building blocks of proteins(monomers). - link together by peptide bonds. Enzymes – proteins that change the rate of a chemical reaction.

Proteins Function- 1. Contracting muscles. 2. Transporting oxygen in the blood. 3.Building structures like hair, nails, horns, and hoofs.

Draw the amino acid-protein

Nucleic Acid - A complex polymer of nucleotides(building blocks) of C, H, O, nitrogen and phosphorus. Ex. DNA and RNA

Nucleic Acids Function-1. stores cellular genetic information -DNA. 2. Helps make proteins-RNA.
