AP Biology Unit 1 Latest Update with Verified Solutions -ose suffix carbohydrates usually end in (gluc-ose, fruct-ose) adhesion the attraction of unlike molecules; water molecules are attracted to other polar surfaces amino acid building block (monomer) of proteins, composed of an amino group and a carboxyl group, a hydrogen atom, and an R-group Amino Acid Examples glutamine, proline, cysteine, lycine, ... atom Smallest form of an element that still displays its particular properties; consisting of a positively charged nucleus and a negatively charged electron cloud. Carbohydrate Examples glucose, fructose, sucrose, starch, glycogen, cellulose, monosaccharides, disaccharides, polysaccharides Carbon, Hydrogen, Oxygen (CHO) elements that makeup both Carbohydrates and Lipids Carbon, Hydrogen, Oxygen, Nitrogen (CHON) elements that make up a protein Carbon, Hydrogen, Oxygen, Phosphorus, Nitrogen (CHOPN) elements that make up a nucleic acid Cellulose A substance (made of sugars) that is common in the cell walls of many organisms charge of the hydrogen atoms in a water molecule slightly positive charge of the oxygen atom in a water molecule slightly negative chemical bond attraction between two atoms by transferring or sharing electrons to attain a stable electron configuration cohesion the attraction of like substances; water molecules are attracted to other water molecules; this is due to the hydrogen bonding between water molecules covalent bond Bond that forms when electrons between atoms are shared. dehydration synthesis reaction that links monomer molecules together, releasing a molecule of water for each bond formed Disaccharide A double sugar, consisting of two monosaccharides joined by dehydration synthesis. Disulfide Bridge The covalent bond between two sulfur atoms (-S—S-) linking two molecules or remote parts of the same molecule. double helix term used to describe the arrangement
