산화 철(II) (Iron(II) oxide, ferrous oxide) 또는 일산화철(1산화철) 또는 산화제일철(산화제1철)은 철 원자에 산소 원자 하나가 결합한 산화 철로, 화학식은 FeO이다. 상온에서 검은색 가루로 존재한다. 산화 철(II)의 광물은 주로 뷔스타이트로 알려져있다.

제조

산화 철(II)는 수산화 철(II)을 진공에서 가열하여 제조할 수 있다.

FeC2O4 → FeO + CO + CO2

화학량론적으로 산화철(II)는 Fe0.95O를 770 °C와 36 kbar에서 가열하여 제조할 수 있다.

반응

FeO는 열역학적으로 575 °C 이하에서 불안정하며, 불균등화 반응으로 금속과 산화 철(II,III)(Fe3O4)을 생성한다.

4FeO → Fe + Fe3O4

구조

산화 철(II)는 암염 구조를 가진 등축정계 구조를 가지며, 철 원자와 산소 원자가 정팔면체의 형태로 위치해 있는 형태이다.

존재

산화 철(II)는 맨틀에서 약 9%를 차지한다.

사용

산화 철(II)는 안료로도 쓰인다. FDA 허가를 받아 화장품이나 문신용 잉크에도 쓰인다. 또한 어항의 인산염을 거르기 위해서도 쓰인다.

Lipolysis

Metabolism involving breakdown of lipids This image illustrates the three separate steps of hydrolysis involved in lipolysis. In the first step, triacylglycerol is hydrolyzed to make diacylglycerol and this is catalyzed by adipose triglyceride lipase (ATGL). In the second step, diacylglycerol is hydrolyzed to make monoacylglycerol and this is catalyzed by hormone-sensitive lipase (HSL). In the last step, monoacylglycerol is hydrolyzed to make glycerol and this is catalyzed by monoacylglycerol...
