  3. Gluteus maximus Gluteus maximus
    Gluteus maximus: The greatest gluteal muscle and the biggest muscle in the human body. The gluteus maximus forms the bulk of the buttocks. It acts to extend the upper leg, spread it, and turn it outward. There are two other gluteal muscles called the gluteus medius and gluteus minimus. Together wit...
  4. Gly Gly
    Gly: Glycine. See also: Amino acid symbols....
  5. Glycemic index Glycemic index
    Glycemic index: An indicator of the ability of different types of foods that contain carbohydrate to raise the blood glucose levels within 2 hours. Foods containing carbohydrates that break down most quickly during digestion have the highest glycemic index. Also called the dietary glycemic index....
  6. Glycine Glycine

  11. Glycopeptide Glycopeptide
    Glycopeptide: A short chain of amino acids that has sugar molecules attached to it. A glycoprotein is similar in structure to a glycopeptide but has a longer chain of amino acids....
  12. Glycoprotein Glycoprotein
    Glycoprotein: A molecule that consists of a carbohydrate plus a protein. Glycoproteins play essential roles in the body. For instance, in the immune system almost all of the key molecules involved in the immune response are glycoproteins. A glycopeptide is similar in structure to a glycoprotein but...
  13. Glycosylated hemoglobin Glycosylated hemoglobin
    Glycosylated hemoglobin: Hemoglobin to which glucose is bound. Glycosylated hemoglobin is tested to monitor the long-term control of diabetes mellitus. The level of glycosylated hemoglobin is increased in the red blood cells of persons with poorly controlled diabetes mellitus. Since the glucose s...
  14. gm (gram) gm (gram)
