(a) Define amylase. (b) What is its function? What is a chemical that results in the death of bacteria? What is the origin of the lactate or lactic acid? List the substances (and proportions) that make up urine. What types of food storage contains the most salt?
Chemical exchange saturation transfer (CEST) imaging is a relatively new magnetic resonance imaging contrast approach in which exogenous or endogenous compounds containing either exchangeable protons or exchangeable molecules are selectively saturated and after transfer of this saturation, detected indirectly thr...
aA certain medium has the following composition: glucose(15g), yeast extract(5g),peptone(5g), KH2PO4 (2g), distilled water(1000ml). To what chemical category dose this medium belong? 某一媒介有以下构成: 葡萄糖(15g),酵母抽提物(5g),胨(5g),磷酸二氢钾(2g),蒸馏水(1000ml)。 对什么化工...
At first blush, the Earth and moon don't seem very similar; one is full of water and life, the other a sterile, airless rock. They do have many chemical substances in common, however. The moon is abundant in sandlike materials that are also found on Earth. Many elements that make up...
The first cofactor was isolated in 1906, in yeast, but cofactors can be organic or inorganic. The most important function of coenzyme A is to aid in oxidizing and synthesizing fatty acids. It is also used as a substrate in the enzymes of all sequenced genomes, and is used in 4% of ...
Nuts and seeds– Excluding grain seeds, there is not much evidence to suggest that humans are sensitive to the types of lectins in tree nuts and most flowering seeds. Yeast– It’s worth noting that “only a few reports are available” about the activity of yeast lectins (8). ...
Ethanol is also called ethyl alcohol. This naming convention, as you may have suspected, applies to all alcohols; the "-anol" suffix may be exchanged with the more cumbersome "-yl alcohol." Knowing that propane is the name of a three-carbon hydrocarbon, can you work out its chemical form...
On the origin of the chemical bimodality of disk stars: A tale of merger and migration The Milky Way's stellar disk exhibits a bimodality in the [Fe/H] vs. [α/Fe] plane, showing a distinct high-α and low-α sequence whose origin is still un... B Tobias - 《Monthly Notices of...
Nucleosomes consist each of the four core histones around which ~146 basepairs of DNA is wrapped. Both DNA and histone proteins carry additional information which relates to gene expression. This information is present in the form of chemical modifications known as 鈥榚pigenetic marks鈥 Aberrant ...
such as a burning sensation when urinating and the presence of sores. Painfulblistersand sores are caused bygenital herpes, but Chlamydia is mostly asymptomatic. An abnormal discharge or pain is caused by a yeast infection, while dysuria is usually caused bygonorrhea, an STD caused by bacteria....
