Gluconeogenesis–de novosynthesis of glucose molecules from simpleorganiccompounds. An example in humans is the conversion of a fewamino acidsin cellular protein to glucose. Metabolic use of glucose is highly important as an energy source for muscle cells and in the brain, andred blood cells. ...
Complex carbohydrates of the nervous system are degraded in lysosomes by the sequential action of a group of exoglycosidases known collectively as the lysosomal hydrolases. Inherited defects in the synthesis, assembly, or turnover of these hydrolases lead to storage diseases in humans (Spranger, ...
Hydroxocobalamin (vitamin B12) is safe in humans and has been approved for the treatment of cyanide poisoning by the US FDA. Given the paucity of neuroprotective measures against hypoxic or ischemic brain injury, further studies examining the neuroprotective effects of sulfide scavengers are warranted....
Why is the joining of four glucose molecules in forming a polysaccharide an example of dehydration synthesis? Explain. Reduction of l-gulose with NaBH_4 leads to the same alditol (d-glucitol) as reduction of d-glucose. Explain. Examine the analogy and how it compares a part to a whole. ...
Turnover in humans of β2-microglobulin: the constant chain of HLA-antigens The turnover of β2-microglobulin, the common subunit of the HLA antigens, has been examined in normal subjects and in some patients with kidney... F.,ANDERS,KARLSSON,... - 《European Journal of Clinical Investiga...
When these hormones are activated, released or triggered, they will stimulate the necessary breakdown of available nutrients to produce energy for the body to function. For example, when you are faced with a dangerous situation, the body goes into fight-or-flight mode, at which point adrenaline...
The use ofLactobacillusspecies as a therapeutic for stress-related disorders in humans has gained significant traction over the last decade. In particular, there is an interest in how ingestion of these supplements in childhood or early-life can shape behaviour. The administration of a singleLactobac...
When the concentration of IgG in the plasma reaches 200% of the normal value, for example, the fractional catabolic rate increases up to 180% of its normal value. In other words, the half-life of IgG is decreased from 21 days to 12 days. 展开 ...
Animals maintain energy homeostasis through the coordinated metabolism of available intracellular nutrients, including glucose, lipids and amino acids. To do so, animals employ complex but elegant molecular mechanisms to integrate the metabolism of these nutrients. In mice for example, under well-fed con...
in Table4are mainly different species ofCandidayeasts, which aside from their opportunistic pathogenicity in humans, are known degraders of lignocellulose-derived compounds such as xylose and different aromatics (Gérecová et al.2015; Holesova et al.2011; Jeffries1981; Krug et al.1985). In ...
