biomolecules
| Question | Answer |
|---|---|
| a class of biomolecules insoluble in water and usually made up of fatty acids; make up cell membranes; used by cells for long-term energy storage; examples are fats, oils, waxes, and steroids | lipid |
| a lipid made from fatty acids that have no double bonds between carbon atoms; solid at room temperature; examples are butter, and animal fat | saturated fat |
| monomer that makes up proteins; contains carboxyl and amino functional groups | amino acid |
| a class of biomolecules that contains carbon, hydrogen, oxygen, and nitrogen; made up of amino acids; make structure of cell membranes, needed for repair and growth; includes enzymes | protein |
| large macromolecule formed from a long chain of monosaccharides | polysaccharide |
| A sugar formed from two monosaccharides joined by dehydration synthesis | disaccharide |
| A single sugar molecule such as glucose or fructose, the simplest type of sugar; monomer of complex carbohydrates | monosaccharide |
| a class of biomolecules that includes sugars, starches, and fiber; contains carbon, hydrogen, and oxygen; key source of energy | Carbohydrate |
| large molecule formed when many smaller molecules bond together | polymer |
| small molecular unit that is the building block of a larger molecule | monomer |
