The Claim

Higher expression of stearoyl-CoA desaturase (SCD) in the loin muscle of Yanbian Yellow cattle does not result in a higher proportion of monounsaturated fatty acids compared to the chuck muscle, indicating that SCD gene expression alone is insufficient to determine muscle fatty acid composition.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In Yanbian Yellow cattle, even when the SCD gene is more active in the loin muscle than in the chuck muscle, the amount of monounsaturated fatty acids is not higher in the loin. This means SCD gene activity by itself does not control the fatty acid profile in these muscles.

See the scientific wording

Despite higher expression of stearoyl-CoA desaturase (SCD) in the loin muscle of Yanbian Yellow cattle, the proportion of monounsaturated fatty acids was not higher in the loin than in the chuck, indicating that SCD gene expression alone does not determine muscle fatty acid composition.

Why this might work

Different muscles develop fat cells at different times during growth; muscles that formed fat cells earlier store more monounsaturated fats from past enzyme activity, and those fats remain even when the enzyme is less active later. Muscles that form fat cells later may have more enzyme now, but they haven't had time to build up the same amount of stored fat.

    Even though the loin muscle makes more of the enzyme that creates healthy fats, it doesn’t end up with more of those fats than the chuck muscle—so making more enzyme doesn’t always mean more fat gets produced.
