A triglyceride with a glycerol molecule on the left and three fatty acids coming off it.

In triglycerides, the main group of bulk lipids, there is one molecule of glycerol and three fatty acids.

At the post-mortem, the pathologist found three causes of death – pneumonia, brain swelling and a fatty liver.

In most naturally occurring unsaturated fatty acids, each double bond has three n carbon atoms after it, for some n, and all are cis bonds.

When all three fatty acids have the formula C < sub > n </ sub > H < sub >( 2n + 1 )</ sub > CO < sub > 2 </ sub > H, the resulting fat is called " saturated ".

In these compounds, the three hydroxyl groups of glycerol are each esterified, typically by different fatty acids.

They are typically found as triglycerides ( three fatty acids attached to one glycerol backbone ).

Butterfat is a mixture of triglyceride, a triester derived from glycerol and three of any of several fatty acid groups.

They are found in living tissues, typically in the form of triglycerides ( three fatty acid chains attached to a glycerol backbone ).

A triglyceride ( TG, triacylglycerol, TAG, or triacylglyceride ) is an ester derived from glycerol and three fatty acids.

Triglycerides are formed by combining glycerol with three molecules of fatty acid.

Ketone bodies are three water-soluble compounds that are produced as by-products when fatty acids are broken down for energy in the liver.

Fats and oils are composed of triglycerides ; three molecules of fatty acids are attached to a single molecule of glycerol.

* Fats consist of a glycerin molecule with three fatty acids attached.

They are typically found as triglycerides ( three fatty acids attached to one glycerol backbone ).

Synthetic tetraesters, which are similar to vegetable oils but with four fatty acid chains compared to the normal three found in a natural ester, are manufactured by Fischer esterification.

Scientists at the time regarded margaric acid, like oleic acid and stearic acid, as one of the three fatty acids which, in combination, formed most animal fats.

Fiber, especially cellulose and hemi-cellulose, is primarily broken down into the three volatile fatty acids ( VFAs ), acetic acid, propanoic acid and beta-hydroxybutyric acid, in these chambers by microbes ( mostly bacteria and well as some protozoa, fungi and yeast ).

Most triglycerides are derived from at least two and more commonly three different fatty acids.

Glycerol has three hydroxyl functional groups, which can be esterified with one, two, or three fatty acids to form monoglycerides, diglycerides, and triglycerides.

In a study of the fatty acid composition of raw meat taken from the hind legs of seven young males ( one to three years old ), 51. 5 % were saturated fatty acids, 29. 9 % monosaturated and 18. 6 % polyunsaturated fatty acids, in chains.

As these three examples show, acids can be solutions, liquids, or solids.

There are three common definitions for acids: the Arrhenius definition, the Brønsted-Lowry definition, and the Lewis definition.

Hydronium ions are acids according to all three definitions.

There are three main classes of biopolymers based on the differing monomeric units used and the structure of the biopolymer formed: polynucleotides, which are long polymers composed of 13 or more nucleotide monomers ; polypeptides, which are short polymers of amino acids ; and polysaccharides, which are often linear bonded polymeric carbohydrate structures.

Despite these differences, all known naturally-occurring codes are very similar to each other, and the coding mechanism is the same for all organisms: three-base codons, tRNA, ribosomes, reading the code in the same direction and translating the code three letters at a time into sequences of amino acids.

George Gamow proposed that the genetic code was composed of sequences of three DNA base pairs known as triplets or codons which represent one of the twenty amino acids.

Most of the structures that make up animals, plants and microbes are made from three basic classes of molecule: amino acids, carbohydrates and lipids ( often called fats ).

* Sulfur, for three essential amino acids and therefore many proteins ( skin, hair, nails, liver, and pancreas ).

* The first step is the condensation of three amino acids —-α-aminoadipic acid ,-cysteine ,-valine into a tripeptide.

Although enzymes can consist of hundreds of amino acids, it is usually only a small fraction of the residues that come in contact with the substrate, and an even smaller fraction — three to four residues on average — that are directly involved in catalysis.

Other than the three major pyrimidine bases presented, some minor pyrimidine bases can also occur in nucleic acids.

* A tripeptide has three amino acids.

Attached to the N-acetylmuramic acid is a peptide chain of three to five amino acids.

RNA and DNA are both nucleic acids, but differ in three main ways:

Dopamine is synthesized in the body from within cells ( mainly by neurons and cells in the medulla of the adrenal glands ) and can be created from any one of the following three amino acids:

These amino acids are provided from natural sources such as the ingestion of various kinds of food, with-tyrosine being the most common of the three.

All three joined The Band's drummer Levon Helm as part of his RCO All-Stars.

A given ( hydrogen-like ) atomic orbital is identified by unique values of three quantum numbers: n, l, and m < sub > l </ sub >.

For example, at the gene locus for the ABO blood type carbohydrate antigens in humans, classical genetics recognizes three alleles, I < sup > A </ sup >, I < sup > B </ sup >, and I < sup > O </ sup >, that determine compatibility of blood transfusions.

The slope field of F ( x ) = ( x < sup > 3 </ sup >/ 3 )-( x < sup > 2 </ sup >/ 2 )- x + c, showing three of the infinitely many solutions that can be produced by varying the Constant of integration | arbitrary constant C.

The transfer of Audacious < nowiki >'</ nowiki > s broadside to Spartiate meant that Captain Maurice-Julien Emeriau now faced three opponents.

E has two clauses ( denoted by parentheses ), four variables ( x < sub > 1 </ sub >, x < sub > 2 </ sub >, x < sub > 3 </ sub >, x < sub > 4 </ sub >), and k = 3 ( three literals per clause ).

An element of water volume on the surface is shown to be subject to three forces: the vertical force due to gravity F < sub > g </ sub >, the horizontal, radially outward centrifugal force F < sub > Cfgl </ sub >, and the force normal to the surface of the water F < sub > n </ sub > due to the rest of the water surrounding the selected element of surface.

There are three naturally occurring isotopes, with < sup > 12 </ sup > C and < sup > 13 </ sup > C being stable, while < sup > 14 </ sup > C is radioactive, decaying with a half-life of about 5, 730 years.

Thus, for example, the English form is is an apparent cognate of German ist, Latin est and Russian < nowiki > jest '</ nowiki >, even though the Germanic, Italic, and Slavic language groups split at least three thousand years ago.

Since the mass numbers of these are 12, 13 and 14 respectively, the three isotopes of carbon are known as carbon-12, carbon-13, and carbon-14, often abbreviated to < sup > 12 </ sup > C, < sup > 13 </ sup > C, and < sup > 14 </ sup > C.

For example, the three familiar allotropes of carbon ( amorphous carbon, graphite, and diamond ) have densities of 1. 8 – 2. 1, 2. 267, and 3. 515 g / cm < sup > 3 </ sup >, respectively.

As a special case, the three naturally occurring isotopes of the element hydrogen are often specified as H for < sup > 1 </ sup > H ( protium ), D for < sup > 2 </ sup > H ( deuterium ), and T for < sup > 3 </ sup > H ( tritium ).
