lipids의 많은 부산물들을 만들어냈다. 따라서 주요한 발효산물들은 분리될 필요가 있었는데 이러한 부산물들을 제거함에 따라 butanol을 얻는데 필요한 비용의 증가를 초래하였다. 뿐만 아니라 1960년대 석유화학의 발전으로 생물학적으로 생산되는 바이오부탄올은 거의 사라지게 되었다. 그러나 최근 원
1.1.2. Cyclooxygenase-prostanoid cascade
Figure 1.1. Metabolism of arachidonic acid
Despite the diverse chemical structure of aspirin-like drugs, the antinociceptive effect of NSAIDs is mainly due totheir common property of inhibiting cyclooxygenases involved in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are n
Lipopolysaccharides (LPS), also known as lipoglycans,
are large molecules consisting of a lipid and a polysaccharide
joined by a covalent bond; they are found in the outer
membrane of Gram-negative bacteria, act as endotoxins and
elicit strong immune responses in animals.
LPS is the major component of the outer membrane of
Gram-negative bacteria, contributing greatly to the structu
1. What are anabolic steroids?
(1) Definition and structure of anabolic steroids
Anabolic steroids - or more precisely, anabolic-androgenic steroids are synthetic derivatives of testosterone.
The effects of anabolic-androgenic steroids mimic those of testosterone. Natually synthesized hormones, such as testosterone, are types of lipids. they have a four-ring carbon skeleton and are synthe
