Recently ... before and the overriding message is that a very broad diet, taking in vital categories of essential nutrients, is better than a narrowly focussed ...

Coenzyme A

... an acetyl group is also referred to as acetyl-CoA . Acetyl-CoA is an important molecule itself. It is the precursor to HMG CoA, which is a vital component in cholesterol and ketone synthesis. Furthermore, it contributes the acetyl group to acetylcholine ; the addition of the acetyl ...

Apoptosis

... genetic system carried out by human papillomaviruses (HPV), a gene called E6 is expressed in a product that degrades p53 protein, which is a vital piece of the apoptotic pathway. This severe interference in the apoptotic capability of cells plays a critical role in the fact that persistent ...

Autotroph

... oxidation of inorganic compounds such as hydrogen sulfide or ferrous iron for energy conservation are chemolithoautotrophs . Autotrophs are a vital part of the food chain . They take energy from the sun or from inorganic sources and convert it into a form (organic molecules) that they use to ...

BLAST

... programs, probably because it addresses a fundamental problem, and its algorithm emphasizes speed over sensitivity. This emphasis on speed is vital to making the algorithm practical on the huge genome databases currently available, although subsequent algorithms can be even faster. Examples of ...

Carnivore

... often recommended to have vegetable supplements (or such containing processed pet foods) as meats designed for human consumption may be lacking in vital nutrients. Cats (not only including domestic cats but also including lions , tigers , and other members of the cat family.) Dogs (again ...

Chlorophyll

... Evidence for chlorophyll Absorbance spectra of by chlorophyll a ( green ) and b ( red ) Chlorophyll can be shown to be vital for photosynthesis by destarching a leaf from a variegated plant and exposing it to light for several hours. (Variegated leaves have green areas ...

Chloroplast membrane

... Chloroplasts contain several important membranes , vital for their function. Like mitochondria , chlorplasts have a double-membrane envelope, called the chloroplast envelope . Each membrane is a ...

Cytoplasm

... the consistency of the cell and to provide suspension to the organelles. It is also a storage place for chemical substances indispensable to life. vital metabolic reactions take place here, for example anaerobic glycolysis and proteic synthesis . See also : microtubules , vesicle ...

Diabetes mellitus

It is known that certain nucleotide sequences specify affinity for DNA binding proteins , which play a wide variety of vital roles, in particular through control of replication and transcription. These sequences are frequently called regulatory sequences , and researchers ...

Extinction

... are predators and directly affect prey species, while at other times they may merely outcompete vulnerable species for limited resources. vital resources including water and food can also be limited during habitat degradation, causing some species to become extinct. Predation, ...

Fermentation

... for a process known as "mashing". During this process, natural enzymes within the malt break down much of the starch into sugars which play a vital part in the fermentation process. Mashing usually takes 1 to 2 hours, and during this time various temperature rests activate different enzymes ...

Photosynthesis

... energy of light to produce food. Ultimately, nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth . It is also responsible for producing the oxygen that makes up a large portion of the Earth's atmosphere . Organisms that ...

Kwashiorkor

... in the older child who has been weaned from the breast once a new sibling is born. When a child is nursing, it receives certain amino acids vital to growth from its mother's milk. When the child is weaned, if the diet that replaces the milk is high in starches and carbohydrates , and ...

Major histocompatibility complex

Nephron

... substances (especially ions ) in the body by filtering it all out first, reabsorbing what should be kept and excreting the rest. This is a function vital to supporting human life. The nephron filters the blood by several processes concentrating the filtrates, reabsorbing ions (such as sodium , ...

Neuron

... of the central nervous system. There are far more glial cells than neurons, and recent experimental results have suggested that glial cells play a vital role in information processing among neurons. Histology and internal structure Nerve cell bodies stained with basophilic dyes will show ...

Paleontology

... lies in the use of fossils to determine the age and nature of the rocks that contain them or the layers above or below. This information is vital to the mining industries and especially the petroleum industry. Simply looking at the fossils contained in a rock remains one of the fastest and ...
