17 terms
Terms | Definitions |
|---|---|
organic compounds | compounds that contain carbon |
structural formulas | similar to Lewis diagrams, but they use a dash in the place of a colon to represent a bond |
biochemistry | chemistry of living things |
carbohydrates | contain carbon, hydrogen, and oxygen, and the ratio of hydrogen to oxygen is typically 2:1 |
monosaccharides | so-called simple sugars |
di-saccharides | made from two monosaccharides and include table sugar or sucrose |
polysaccharides | chains of monosaccharides and are commonly known as starch and glycogen |
starch | formed in plants |
glycogen | found in animals |
lipids | fats and steroids |
fats | made of fatty acids and glycerol, each fat molecules is made up of one glycerol molecule attached to three fatty acids |
saturated fats | bonds between the carbons are single |
unsaturated fats | bonds between carbons are double or triple |
proteins | made of amino acids, examples are enzymes,collagen, making up cartilage, tendons and bones, and keratin, hair and nails |
amino acids | about 20 types, linked in chains, and the sequence determines the |
dehydration synthesis | a reaction in which small units, such as monosaccharides or amino acids, are joined to form larger molecules, in this reaction one molecule gives up a hydrogen atom and the other an OH to form water, and the two molecules bond |
hydrolosis | a large molecule is broken down into smaller molecules by adding water H2O and putting the H and the OH back |
