What are some other organic molecules? Lipids Fats

What are lipids used for in our bodies? Major component of cell membranes Important energy source

What are lipids made up of? A fat consists of a Glycerol molecule and 3 Fatty Acid chains

Fats can be Saturated or Unsaturated Can you see the difference? Unsaturated fats have double bonds in the fatty acid chains

Unsaturated vs. Saturated Fats Diets rich in saturated fats can lead to the build up of plaques in blood vessels.

What are steroids? Some hormones are steroids Very important component of the cell membrane

What organic molecule does this cat have too much of? LIPIDS

What is another category of organic molecules? Proteins

Proteins have many functions: Proteins are enzymes, found in cell membrane, make up antibodies, and much more

What are proteins made up of? Proteins are made up of polymers of amino acids

How do we build proteins? The functional groups of proteins interact with each other to form polymers of amino acids (proteins). Dehydration Synthesis

What are Polypeptides? Polypeptides are chains of amino acids Proteins are long chains of polypeptides

How many amino acids are there? There are only 20 amino acids, but there are millions of different types of proteins.

Protein Shape: 1)The sequence (order) of amino acids in a protein determine its shape 2) The shape of a protein determines its activity

What does Denaturation mean? An unfavorable change in temperature, pH, or some other quality of the environment can cause a protein to unravel and lose its normal shape Denatured proteins do not function properly! INCORRECT FORM….. NO FUNCTION!

What is another group of organic compounds? Nucleic Acids

DNA & RNA are Two Kinds of Nucleic Acids The building block of nucleic acids are: Nucleotides

What is a nucleotide made of?

What is DNA responsible for? Our characteristics or traits

Nucleic Acids DNA or RNA Nucleotides Phosphate Sugar Base

What are the 4 Organic Molecules: Carbohydrates Lipids Nucleic Acids Proteins
