There appears to be little risk of contamination by microorganisms, proteins, lysophospholipids, cholesterol, and trans-fats.

Feedlots achieved faster growth rates by feeding proteins in the form of grains and soybeans.

These fixatives preserve tissues or cells mainly by irreversibly cross-linking proteins.

During all three phases, the cell grows by producing proteins and cytoplasmic organelles.

Many biologists discounted the importance of this finding on the ground that it was probably the result of contamination by terrestrial proteins.

DNA has many features that allow its sequence-specific recognition by proteins.

For example, it can function as an antiseptic in topical creams to kill bacteria by denaturing proteins.

Phosphorylation by other proteins in the destruction complex subsequently binds Axin to this tail as well.

Damage to the membranes of organelles by monomeric or oligomeric proteins could also contribute to these diseases.

Fire also led to improved nutrition by cooked proteins.
