Term | Definition |
amino acids | has a central carbon atom bonded to a hydrogen atom and three groups that include an amino group (-NH2), an acidic group (-COOH), and an R group (remainder of the molecule) |
enzymes | a biological catalyst that speeds up the chemical reactions that occur in the body; does this by lowering the activation energy required for each chemical reaction |
hormones | chemical messenger that travels through the body and influences cell functions, such as metabolism, growth and development, and homeostasis. |
peptide bond | C-N covalent bonds that join two amino acids |
plasma | the liquid portion of the blood; mainly consists of water; 7-8% proteins. |
primary proteins | a linear sequence of amino acids linked by peptide bonds (C-N) that formed by dehydration synthesis. |
primary structure | linear sequence of amino acids joined by peptide bonds; formed by dehydration synthesis |
proteins | polymers with amino acid monomers; include all antibodies, enzymes, most hormones, and much of structural support in the tissues of our bodies; consists of polymers made from the 20 different amino acids found on the cells. |
secondary structure | looks like proteins coiled into a helix or pleated sheet; caused by bonding of the H atoms in the amino groups and the O atoms of close range acidic groups. |
quarternary structure | consisting of more than one amino acid chain. |
quarternary proteins | made of two or more tertiary proteins joined together |
R group | the remainder of the amino acids |
tertiary structure | caused by the covalent bonding between the R groups in the structure (between the alpha helices and pleated sheets) |
tertiary proteins | a three-dimensional structure created by a secondary protein that has folded back upon itself. |
