BIO 12-MOD1/1.2D

Lesson 1.2D Vocabulary Words

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, so named because it is the remainder of the molecule
enzyme 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 a 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% to 8% of plasma consists of proteins
primary proteins a linear sequence of amino acids linked by peptide bonds (C-N) that formed by dehydration synthesis
primary structure it is the exact specification of its atomic composition and the chemical bonds connecting those atoms (including stereochemistry)
proteins polymers with amino acid monomers; include all antibodies, enzymes, most hormones, and much of structural support in the tissues of our bodies; structure consists of polymers made from the twenty different amino acids found in cells
quaternary structure it s the arrangement of multiple folded protein or coiling protein molecules in a multi-subunit complex
quaternary proteins made of two or more tertiary proteins joined together
R-group Amino acids have a central carbon atom bonded to a hydrogen atom and three groups that include an amino group (–NH2), and acidic group (–COOH), and an R group. The R group is so named because it makes up the remainder of the molecule.
secondary proteins looks like a primary protein coiled into a slinky
tertiary structure refers to a protein's geometric shape. The tertiary structure will have a single polypeptide chain "backbone" with one or more protein secondary structures, the protein domains. Amino acid side chains may interact and bond in a number of ways.
tertiary proteins a three-dimensional structure created by a secondary protein that has folded back upon itself
