Producer of chemicals derived from coal tar , located in china . products include derivatives of naphthalene , anthracene , phenanthrene , and fluorene -生产销售乙醛酸乙二醛醇脂- 12草酸等有机化工品，包括公司简介产品介绍等
Manufacturer of pharmaceutical intermediates and fine chemicals in china . products include a range of aromatic amines , as well as intermediates for specific apis -主要生产对硝基苯甲酸， 3 -戊酮， dl -对羟基苯甘氨酸， dl -对羟基苯海因，乙醛酸产品。
It may be synthesized directly from ammonia , carbon dioxide , and a donated methyl group ; derived from serine ; or derived from glycerate 3 - phosphate by transamination of glyoxylate 甘氨酸来源于丝氨酸，或由乙醛酸经转氨作用生成的甘油3 -磷酸转化而成。
It is broken down by a reversal of the first two pathways , or by deamination to glyoxylate , followed by conversion to malic acid and further breakdown in the krebs cycle 它可在前两种方法中被分解，或者通过脱氨作用生成乙醛酸，然后转化为苹果酸，进一步在三羧酸循环中被分解。
Acetyl coa plays a key role in metabolism , being a precursor of the krebs cycle and glyoxylate cycle , and the starting point for synthesis of fatty acids , terpenes , and some amino acids 它在新陈代谢的过程中扮演非常重要的角色，是三羧酸循环和乙醛酸循环的前体物质，而且还是合成脂肪酸，萜类以及一些氨基酸的起始。
In the course of oxidation , reaction temperature should rise step by step , and in the late stage , reduced pressure distillation should follow so that the concertration of glyoxalic acid can rise and production rate of allantoin can rise up to 40 % 在氧化反应的过程中逐步地提高反应温度，反应后期进行减压浓缩，提高了乙醛酸的浓度，缩短了氧化时间，并使尿囊素产率达到40 % 。
China haohua group corporation xuanhua co . , ltds is the biggest manufacturer of glyoxylate in the homeland , and at the same time is a selective enterprise based on the civil dynamite equipment . it actively takes friendly business contact with numerous companies and enterprises both here and abroad . it takes high grade and low - cost fine chemical products as medium and benefits each other to promote the development of both side and gain the same ends 中国昊华集团宣化有限公司作为国内最大的乙醛酸生产厂家，同时以民爆器材产品化肥产品电石等为支柱的重点企业积极与国内外广大公司企业进行友好业务往来，以优质廉价的精细化工产品为媒介，双方互惠互利促进彼此间的发展，达到共同的目的。
