Biochemistry vocab
| Term | Definition |
|---|---|
| Lipids | 1 glycerol and 3 fatty acids that store energy, are very concentrated, have twice as much energy as carbohydrates, are stored in bonds, cushion organs, and insulate the body. |
| Saturated Fats | Most animal fats that contain no double bonds, which then contain more hydrogen, and they also contribute to heart disease. |
| Unsaturated Fats | Plant and fish fats that contain double bonds, which then contain less hydrogen, and is a better choice for your diet. |
| Cholesterol | Good molecule in cell membranes and makes hormones from it such as testosterone, estrogen, and insulin, but too much of this in blood may lead to heart disease. |
| Phospholipids | The lipid that makes up cell membranes. |
| Hydrophillic | The phosphate is on the outside touching water. |
| Hydrophobic | The lipid chain is on the inside away from the water. |
| Carbohydrates | Simple sugars that are used during cellular respiration to produce energy (ATP) and occurs in the mitochondria. |
| Monosaccharides | Simple sugars that provide energy to the cells during cellular respiration such as glucose. |
| Disaccharides | Made of two monosaccharides joined together such as sucrose. |
| Polyssacharides | Long chains of monosaccharides bonded together. |
| Starch | Energy storage in plants. |
| Glycogen | Energy storage in animals. |
| Cellulose | Material that makes up cell walls. (aka dietary fiber) |
| Chitin | Material that makes up insect exoskeletons |
| Synthesis (aka Dehydration Synthesis) | The process of breaking a larger molecule (complex macromolecule/ polymer) from 2 smaller simpler molecules (monomers) by removing water. |
| Digestion (aka Hydrolysis) | The process of breaking a larger molecule (complex macromolecule/ polymer) into two smaller simpler molecules (monomers) by adding water. |
| Nucleic Acids | Long organic molecules made of carbon, hydrogen, nitrogen, and phosphorus that contain the instructions that cells need to carry out all the functions of life such as DNA and RNA. |
| Nucleotides | Made of phosphate, sugar, and nitrogenous bases. |
| DNA | Genetic material that carries information about an organism that is passed on from parent to offspring, which directs all of the cells functions and it's located in the nucleus. |
| RNA | Plays an important role in the making of proteins and is located in the nucleus and the cytoplasm. |
| Protein | Long organic molecules made of carbon, hydrogen, oxygen, and nitrogen that is responsible for growth and repair. |
| Amino acids | Smaller molecules that make up proteins and the order that they bond together determine the protein's shape and function. |
| Primary Structure | Sequence |
| Secondary Structure | Interaction of R Groups |
| Tertiary Structure | 3D Shape |
| Quaternary Structure | 2+ protein chains making up a protein |
