Product Introduction
Bioactivity
| 名称 | (S)-2-Hydroxy-3-phenylpropanoic acid |
| 描述 | (S)-2-Hydroxy-3-phenylpropanoic acid (L-(−)-3-Phenyllactic acid) is a chiral aromatic compound involved in phenylalanine metabolism. It is likely produced from phenylpyruvate via the action of lactate dehydrogenase. The D-form of this organic acid is typically derived from bacterial sources while the L-form is almost certainly endogenous. Levels of phenyllactate are normally very low in blood or urine. High levels of PLA in the urine or blood are often indicative of phenylketonuria (PKU) and hyperphenylalaninemia (HPA). PKU is due to lack of the enzyme phenylalanine hydroxylase (PAH) so that phenylalanine is converted not to tyrosine but to phenylpyruvic acid (a precursor of phenylacetate). |

6)。腺苷是一种重要的神经调节剂,在胼胝体、下丘脑和丘脑中强度较低,而在端脑和小脑中含量很高。脂质,特别是磷脂(PLs)在大脑中表现出特定的空间分布。例如,磷脂酰胆碱(PC)‐36:1,磷脂酰丝氨酸(PS)‐36:1 和磷脂酸(PA)‐34:1 几乎仅出现在胼胝体和内囊中,而磷脂酰乙醇胺(PE)‐40:6 表现出完全相反的空间分布。 图 6 | 大鼠脑中代表性代谢物的 MSI 原位代谢谱分析有助于深入理解代谢重编程和肿瘤的发展机制。课题组通过 AFADESI-MSI 分析食管癌组织的冷冻
中缺乏苯丙氨酸羟化酶,来自食物中的苯氨酸不能形成酪氨酸,而经转氨酶的作用转变为苯丙酮酸。大量苯丙氨酸及苯丙酮酸聚积在血和脑脊液中并随尿排出。由于血液及体液中苯丙氨酸过剩而竞争性抑制酪氨酸酶,酪氨酸转化为多巴的反应受阻因而,影响到黑色素的合成,所以患者皮肤和毛发含黑色素多少,颜色较浅。多巴又肾上腺素合成的间物,酪氨酸代谢障碍使体内肾上腺素浓度降低。 大量的苯丙氨酸除分解为邻羟基苯乙酸外,还通过苯丙酮酸代谢产生苯乳酸,苯乙酸和苯乙酰谷酰胺,大量从尿中或汗中排出,发出鼠嗅味。
