which animals and humans should take into the body, if they cannot synthesize ascorbic acid. This is the l-enantiomer of the ascorbic acid and the d- enantiomer has no significant role in biological systems. As
As another significant difference between citric acid and ascorbic acid, we can say that the citric acid has three carboxyl groups, and they can donate protons when acting as acids, but in ascorbic acid, there is not any –COOH groups (if the ring opens there can be a –COOH). The prot...
The difference spectra before and after oxidation of l-ascorbic acid (AsA) by ascorbate oxidase (EC 1.10.3.3) were measured using a recording spectrophotometer. A linear relationship was found between the peak height of difference spectra and the concentration of AsA. The AsA content in plant ...
Answer to: What is the difference between Dietary Reference Intake (DRI) and Recommended Dietary Allowance (RDA)? What do EAR, AI, and UL stand...
The same measurements were performed using a buffer solution without BSA, and the F values were calculated using the measured fluorescence intensity as a blank. Molecular docking simulation between vitamin E and BSA With regard to the ligands, 3D structures of Toc and T3 analogs were obtained as...
Using standard additions and Zeeman effect background correction,the linear range of Pb content was between 10 to 50 μg/L,and the recovery rate was 90%~110%. 研究了石墨炉原子吸收法测定葡萄酒中微量铅的适宜条件,采用标准加入法和塞曼效应校正背景,铅的线性范围为10μg/L～50μg/L,回收率为90...
Finally, the DEseq2 package was employed to perform DEG analysis between white- and red-sarcocarp pomelo [28]. Genes with |log2FoldChange| ≥ 2 and adjusted p-value ≤ 0.01 were considered to be significantly differentially expressed. The GO annotation of pomelo genes was assigned using the...
Regarding the taste and appearance, there were differences between the breads based on the GF mixture compared to the wheat and spelt breads. Within the GF breads and the wheat and spelt breads, however, blinding was possible (Figure S1). All breads were packed in the same neutral bags. We...
Here’s the deal: when determining the SPF of your sunscreens, researchers slather them on clean, freshly-cleansed skin with no other product in between. Think about it: anything that you apply on your skin before sunscreen could potentially make it harder to spread and get an uneven applicat...
Before treatment no significant difference was observed between males and females in the l-ascorbic acid and d-glucaric acid excretion. On the days of drug treatment there was an increase in l-ascorbic acid excretion, which was significantly higher in males than in females. d-glucaric acid ...
