Dr. Judson Welcher testified on cross-examination that his experiment using a Lexus SUV and blue paint to depict Karen Read's alleged collision with John O'Keefe was reputable after attorney ...

Starch provides the major source of caloric intake in many diets. Cleavage of starch into malto-oligosaccharides in the gut is catalyzed by pancreatic α-amylase. These oligosaccharides are then ...

There were various end products after hydrolysis of soluble starch by amylase. Maltose (G2), maltotriose (G3), maltotetraose (G4), and maltooligosaccharides occurred after 15 min and ...

How early humans evolved to eat starch, why that matters In the 1960s, scientists discovered that some people produced extra amylase in their saliva. But it has only been in the past few years that ...

A University at Buffalo study reveals that genes aiding in carbohydrate digestion began evolving over 800,000 years ago, even before farming. By analyzing genomes, researchers found hunter-gatherers ...

Two new studies found that ancient human ancestors carried a surprising diversity of genes for amylase, an enzyme that breaks down starch. Skip to content Skip to site index.

Gokcumen’s previous research showed that domesticated animals living alongside humans, such as dogs and pigs, also have higher amylase gene copy numbers compared to animals not reliant on starch-heavy ...

Some human populations gained extra genes to help break down starch in only 12,000 years. Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday.

The amylase test is also used to check on people with cystic fibrosis (CF). That’s a disease that causes lung infections. It can also make it hard for your body to absorb nutrients from food.

In a tube containing 1 mL of phosphate buffer (100 mmol L-1, pH 6.9), 100 µL of α-amylase (final concentration 0.15 U mL-1 in phosphate buffer) was added and incubated at 37 °C for 7.2 min for ...
