The approximate biotin requirements of breeding hens have been established and the embryos examined for gross pathological symptoms and the approximate age at death are recorded. Cravens, W.W., W., & Sebesta, M.A. (1944). Effect of biotin deficiency on embryonic development in the domestic fowl.

Isoleucine (symbol Ile or I) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH+3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biologica

Dimeric members of the avidin family are also found in some bacteria. In chicken egg white, avidin makes up approximately 0.05% of total protein (approximately 1800 ÎŒg per egg). The tetrameric protein contains four identical subunits (homotetramer), each of which can bind to&nbs

Albert Imre Szent-Györgyi[a] de NagyrĂĄpolt (Hungarian: nagyrĂĄpolti Szent-Györgyi Albert Imre; September 16, 1893 – October 22, 1986) was a Hungarian biochemist who won the Nobel Prize in Physiology or Medicine in 1937. He is credited with first isolating vitamin C and discovering t

After a magnesium deficient diet for 5 to 8 days, young rats showed vasodilatation, hyperirritability, and latent tetany. Brief exposures to the sound of a resonated buzzer elicited severe tonic-clonic convulsions. When such a diet was continued for 10 to 23 days, sensitivity increased with death re

Intrinsic factor (IF), cobalamin binding intrinsic factor, also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells (in humans) or chief cells (in rodents) of the stomach. It is necessary for the absorption of vitamin B12 later on in the distal ileu
