Insulin is a naturally occurring hormone made by the pancreas that helps our body use or store the glucose (sugar) it gets from food. For people with diabetes, either the pancreas does not make enough insulin to meet the body's requirements, or the body cannot properly use the insulin that is made.
The yellow color in normal urine comes from a substance known as urochrome. Urochrome is also known as urobilin and is the result of hemoglobin breakdown. Hemoglobin is the protein in red blood cells that enables oxygen to be taken around the body.
Why is my urine yellow. Unlike most of the other colors like red, pink, orange, grey (cloudy) or brown, the color yellow is actually normal for human urine to exhibit. Although the urine of a fit individual would most likely be nearly clear or transparent, it will nonetheless, have a slight yellow tinge to it and that is perfectly healthy.
