What is the difference between linoleic and linolenic acid?

Linoleic acid, also known as linolic acid or linoleate, is a polyunsaturated omega-6 fatty acid. Nutritionally, it is essential to the diets of mammals and is required during the molecular breakdown that takes place in prostaglandins and cell membranes. Its molecular structure is composed of 18 carbon atoms, 32 hydrogen atoms and two oxygen atoms.\n\nLinolenic acid, also known as alpha-Linolenic acid and linolenate, is an essential omega-3 fatty acid used in the formation of prostaglandins. It is commonly found in seeds, nuts and vegetable oils. Its molecular structure is composed of 18 carbon..

What animals eat corn?

Corn is a versatile crop that is used in products such as baby foods, cereals, salad dressings and soups. Many non-food items such as laundry detergent and paint also utilize the properties of corn during the manufacturing process. Corn is not always yellow; varieties of black, blue, purple, red and white are also grown. Its shelf life is second to none, with scientists being able to pop kernels from 1,000 years ago.

What is the function of the vacuole?

Vacuoles are membrane-bound organelles that are found in cells of plants, animals and fungi. Plant cells tend to have a large central vacuole, while the vacuoles in animal cells tend to be smaller. The main function of vacuoles is to contain the waste products of the cells and isolate them from the rest of the organelles and the cytoplasm. Vacuoles maintain an acidic pH internally. This allows them to denature misfolded proteins transferred to the vacuole from the cytoplasm. The vacuoles can also help remove unwanted or toxic materials from the cells by exporting them to the cell membrane, whe..

What information is on a pH scale chart?

PH is a chemical property that describes the amount of hydrogen ions within a solution. A substance with a high concentration of hydrogen ions has a low pH and is an acid. A substance with a low concentration of hydrogen ions has a high pH, and is a base. Pure water has a pH of 7, which is in the middle of the pH scale. Water is neither as an acid or a base, but a neutral solution.\nExamples of acids include the digestive fluids in the stomach, vinegar and soda. Examples of bases include baking soda, bleach and liquid drain cleaner. Substances that do not easily undergo pH changes are buffers ..

How fast is terminal velocity?

Terminal velocity refers to the fact that, although an object falling on earth is subject to the pull of gravity, there will come a point where the opposite drag on the object from the wind will balance out the force of gravity and no further acceleration will be achieved. The shape of the object affects the dragging effect of the wind and this is why skydivers can change the speed of their fall by changing the shape of their bodies as they fall. When the parachute opens, the terminal velocity is reduced to about 12 mph - or a safe speed to land.

What do we get from trees?

Silvichemicals are chemicals humans get from trees. These chemicals are found in many everyday products. After pulping wood, the byproducts make membranes for artificial kidneys, blankets, blouses, cellophane, ceramics, electrical insulation, insecticide spray, oil filters, rayon, tea bags, twine and vanillin.\nMany products come from living trees. Fruits, nuts, herbs, spices, rubber, seeds, frankincense, maple syrup and tree oils are common products humans gather from trees that do not get cut down. Products from solid wood include planks for building houses, furniture, chests, shipping palle..

What is natural light?

People often look for natural lighting when they purchase or build a home. Natural lighting is often bright enough to allow people to avoid turning on artificial lighting sources during the day, reducing how much energy a home uses. Whiles windows are the most common source of natural lighting, sunroofs or skylights are sometimes installed in ceilings to allow in natural light. Some homeowners enjoy natural lighting because it connects them to nature, with some people using it as an alarm clock.

Where do tidal waves occur?

Tidal waves are formed by gravitational forces of the sun, moon and earth. The gravitational pull of the sun and moon tug on the ocean, causing waves to swell. As the earth completes its rotation, the tides move in and out. When the waves meet the shore, they are pushed back by the hard surface.\nTidal waves should not be confused with tsunamis. Tsunamis are powerful ocean waves caused by geological disturbances instead of gravitational pulls. Geological disturbances that cause tsunamis include earthquakes, landslides and volcanic eruptions.

Why are phenols more acidic than other alcohols?

Phenol is a benzene ring with one hydrogen atom replaced with a hydroxyl (OH-) group. Benzene rings are often depicted as having alternate double and single bonds, but in actuality, all the bonds have the same length, which is shorter than a typical single bond, but longer than a typical double bond. This is because the pi electrons are actually delocalized across the entire ring. In other words, there are no localized single or double bonds between atoms. Instead, the valence electrons are able to travel around the whole ring.\nThis property of benzene is what gives phenol the properties of a..

Is starch a polysaccharide?

Polysaccharides are sugars that consists of multiple simple sugar units. The simple sugar units are known as monosaccharides, which only consist of one simple sugar unit. Polysaccharides form when numerous monosaccharides bind together to form long-chain compounds. Many of the common polysaccharide compounds, including starches, contain the monosaccharide glucose as their simple sugar unit. This allows polysaccharides to be utilized by plants and animals as a source of glucose.
