HONEY JANE ESTARIJA bs-biology MW 1:00 - 2:30 & 3:00 – 6:00 A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are

scientific name is Oreganum vulgare‚ and its name is Greek in origin‚ meaning "joy of mountains." Oil of oregano is used in cooking‚ as well as for massage. The essential oil of oregano can be extracted from the leaves through distillation‚ yielding the concentrated benefit of the bulk oregano herb for medicinal and therapeutic purposes. However‚ oil of oregano can be made from an infusion of oregano in base-carrying oil. Uses for Oil of Oregano: • Sinus Congestion‚ Colds and Sore Throats‚ and

Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

Publication No. 11137 Enzyme Activity Guided Inquiry Lab Turnip Peroxidase Introduction Peroxidase enzymes are widely distributed in plants and animals‚ including bacteria‚ to protect cells against the effects of oxidative stress and cell damage due to hydrogen peroxide. Peroxidases are easily extracted from turnips and other root vegetables and provide a model enzyme for studying enzyme activity—how the rate of an enzyme-catalyzed reaction depends on biotic and abiotic factors.
