Acidic: A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.
Agglutination: occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. This term is commonly used in blood grouping. This occurs in biology in three main examples: The clumping of cells such as bacteria or red blood cells in the presence of an antibody or complement.
Albumen: egg white, or the protein contained in it.
Albumin: are a family of globular proteins, the most common of which are the serum albumins. All the proteins of the albumin family are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation.
Alkaline (diet): describes a group of loosely related diets based on the belief that certain foods can affect the acidity and pH of bodily fluids, including the urine or blood, and can therefore be used to treat or prevent diseases.
