Urolithins are microflora metabolites of dietary ellagic acid derivatives, such as ellagitannins. [1] They are produced in the gut , and found in the urine in the form of urolithin B glucuronide after absorption of ellagitannins-containing foods, such as pomegranate . [ 2 ]
Urolithin A is not known to be found in any food but rather forms as the result of transformation of ellagic acids and ellagitannins by the gut microflora in humans. [ citation needed ] Sources of ellagitannins are: pomegranates, nuts, some berries (raspberries, strawberries, blackberries, cloudberries), tea, muscadine grapes, many tropical ...
Urolithin B is found in the urine in the form of urolithin B glucuronide. [citation needed] See also. Glucuronide. Glucuronic acid; Pomegranate ellagitannins;
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The bones were initially thought to be from the second or third century AD even though the arrangement of the body in a fetal position was atypical for the Roman period.
In the lower leg, the tibia and fibula are two parallel bones that complete the lower half of the knee joint. The tibia, located medially, bears most of the body's weight, while the fibula, positioned laterally, is smaller and supports leg structure. Further down the leg are the metatarsal bones, found near the distal end of the hindlimb.
The bones were determined to be up to 47,500 years old. Until now, the oldest Homo sapiens remains from northern central and northwestern Europe were about 40,000 years old.
