Biochemistry vocab

TermDefinition
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
