Biological Molecules free essay sample

What is the building block of a carbohydrate? Monosaccharides Amino acids are found in which type of macromolecule? Polypeptide Name 2 molecules that you constructed that contain carboxylic acid groups. 1. Carboxyl 2. Glycine Name 2 molecules that you constructed that contain hydroxyl groups. 1. Alanine 2. Glucose Explain the difference in structure between saturated and unsaturated fatty acids. Why is this difference important in the body? Saturated fats have one fatty acid chain with a single covalent bond between the carbon atoms. Unsaturated fatty acids have 2 or more double bonds between the carbon atoms. The longer fatty acids chains found in saturated fats are packed closely together, which causes to form a solid. Unsaturated fats are short and cannot be packed to together because of the double bond. 6.
