An iron protein. The rat liver enzyme is an enzyme system involving cytochrome b5 and EC 1.6.2.2, cytochrome-b5 reductase. The ferricytochrome b5 produced is reduced by NADH and cytochrome-b5 reductase (EC 1.6.2.2).

Angus and Wagyu steers consuming high-roughage diets exhibit large differences in adipose tissue fatty acid composition, but there are no differences in terminal measures of CD activity or gene expression, overview
Angus and Wagyu steers consuming high-roughage diets exhibit large differences in adipose tissue fatty acid composition, but there are no differences in terminal measures of CD activity or gene expression, overview
Co2+ has a reducing effect on the DELTA9-desaturase indices [(product of DELTA9-desaturase)/(product of DELTA9-desaturase + substrate of DELTA9-desaturase)] of milk for myristoleic acid, palmitoleic acid, oleic acid, and rumenic acid, there are no differences in DELTA9-desaturase indices between Co2+-EDTA and Co2+-acetate
enzyme activities of 33 to 39 nmol/g tissue/7 min in subcutaneous adipose tissue, 61 to 89 nmol/g tissue/7 min in interfascicular adipose tissue, 118 to 141 nmol/g tissue/7 min in duodenal mucosal cells and 9 to 21 nmol/g tissue/7 min in liver of Angus steers fed with whole cottonseed or grain source, respectively
enzyme activity in interfascicular adipose tissue ranges from 14.4 to 23.9, in subcutaneous adipose tissue from 32.5 to 44.4, in duodenal mucosal cells from 4.34 to 5.29 and in liver from 0.342 to 0.786 nmol/mg protein/7 min under diets based on corn, flaxseed, sorghum or whole cotton seed, respectively
enzyme activity in interfascicular and subcutaneous adipose tissues, or in duodendal mucosal cells and liver is not affected by diets based on corn, flaxseed, sorghum or whole cottonseed
SCD enzyme activities in interfascicular and subcutaneous adipose tissue, duodenal mucosal cells and liver are not affected by dietary whole cottonseed or grain source
Angus and Wagyu steers consuming high-roughage diets exhibit large differences in adipose tissue fatty acid composition, but there are no differences in terminal measures of SCD activity or gene expression
enzyme activity and fatty acid composition in response to different feeding conditions, overview, stearoyl-CoA desaturase activity in the s.c. adipose from the tail-head region do not differ among corn oil supplementation levels. Similarly, SCD mRNA level do not differ among oilsupplementation levels
the level of SCD protein expression in cumulus cells does not change when cumulus-oocyte complexes (COCs) are exposed to saturated stearic acid during maturation
Angus and Wagyu steers consuming high-roughage diets exhibit large differences in adipose tissue fatty acid composition, but there are no differences in terminal measures of SCD activity or gene expression
chemical SCD1 inhibition in the presence of stearic acid results in a significant induction of apoptosis in cumulus cells of matured cumulus-oocyte complexes. SCD1 inhibition does not affect the levels of palmitic acid and its desaturated form, palmitoleic acid
cumulus cells can desaturate the potentially toxic stearic acid into oleic acid via stearoyl-CoA desaturase (SCD) activity, cumulus cells protect the oocyte against toxicity by saturated fatty acids. Stearoyl-CoA desaturase 1 activity is related with increased lipid storage in cumulus cells. The level of SCD protein expression in cumulus cells does not change when cumulus-oocyte complexes (COCs) are exposed to saturated stearic acid during maturation
