Day 18 S. Chirumamilla Day 18 S. Chirumamilla Chemistry of Cells

Carbohydrates What is it? - They are organic compounds made of carbon, hydrogen, and oxygen atoms in the proportion of 1:2:1.

Why are carbohydrates important to organisms? They are the key source of energy, and they are found in most foods-especially fruits, vegetables, and grains.

Monosaccharides What is it? Monosaccharides are single sugars. What does it help build? - Monosaccharide help in building blocks of carbohydrates.

Polysaccharides Polysaccharides are chains of three or more monosaccharides. Starches are examples of polysaccharides.

Monosaccharides What is a disaccharide? They are double sugars formed when two monosaccharides are joined. Sugar is an example of a disaccharide.

Lipids What is it? Lipids are nonpolar molecules that are not soluble. Lipids do not dissolve in water.

Lipids Examples of lipids are: fats, phospholipids, steroids, and waxes.

Protein What is it? Protein is a molecule formed by linked smaller molecules called amino acids. Amino acids are the building blocks of proteins

Protein Examples of proteins are: Legumes, eggs, milk, fish, poultry

Nucleic Acids What is a nucleic acid? It is a long chain of smaller molecules called nucleotides. What is a nucleotide? A nucleotide has three parts: a sugar, a base, and a phosphate group, which contains phosphorus and oxygen atoms.

Nucleic Acids What is DNA? Deoxyribonucleic acid, consists of two strands of nucleotides tat spiral each other. What is RNA? - Ribonucleic acid, may consist of a single strand of nucleotides or of based-paired nucleotides.

Day 18 S. Chirumamilla ATP What is it? - Adenosine triphosphate is a single nucleotide with two extra energy-storing phosphate groups. Why is it important to cells? ATP is the energy currency of the cell.

Agenda Create a graphic organizer for the following words: carbohydrate monosaccharide lipid protein amino acid nucleic acid nucleotide Hint: Use your text to help define the words.
