The anhydroglucose unit (AGU) refers to a single sugar molecule in a polymer. Each AGU is reduced to its functional groups, 3 hydroxyl groups per AGU. Each AGU is reduced to its functional groups, 3 hydroxyl groups per AGU.
form under biological conditions), and a side chain consisting of a hydroxymethyl group, classifying it as a polar amino acid. It can be synthesized in the human body under normal physiological circumstances, making it a nonessential amino acid. It is encoded by the codons UCU, UCC, UCA, UCG, AGU and AGC.
Arginine is the amino acid with the formula (H 2 N)(HN)CN(H)(CH 2) 3 CH(NH 2)CO 2 H. The molecule features a guanidino group appended to a standard amino acid framework. At physiological pH, the carboxylic acid is deprotonated (−CO 2 − ) and both the amino and guanidino groups are protonated, resulting in a cation.
Aspartylglucosaminuria (AGU) is an inherited disease that is characterized by a decline in mental functioning, accompanied by an increase in skin, bone and joint issues. The disease is caused by a defect in an enzyme known as aspartylglucosaminidase .
MDP, which is the basic unit of peptidoglycan, was initially used as the active component of Freund's adjuvant. [28] Peptidoglycan from Staphylococcus aureus was used as a vaccine to protect mice, showing that after vaccine injection for 40 weeks, the mice survived from S. aureus challenge at an increased lethal dose .
For each codon (square brackets), the amino acid is given by the vertebrate mitochondrial code, either in the +1 frame for MT-ATP8 (in red) or in the +3 frame for MT-ATP6 (in blue). The MT-ATP8 genes terminates with the TAG stop codon (red dot) in the +1 frame. The MT-ATP6 gene starts with the ATG codon (blue circle for the M amino acid) in the ...
Glycosaminoglycans [1] (GAGs) or mucopolysaccharides [2] are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a ...
N(4)-(beta-N-acetylglucosaminyl)-L-asparaginase is an enzyme that in humans is encoded by the AGA gene. [5]Aspartylglucosaminidase is an amidohydrolase enzyme involved in the catabolism of N-linked oligosaccharides of glycoproteins.
