L-Serine is a non-essential amino acid, which means that it is required for the human body to properly function, but does not need to come from an outside source. Instead, it is typically produced within the body from metabolites, such as glycine. Serine, also known as Ser, is a proteinogenic amino acid. This means it is one of the 22 amino acids that are part of the standard human genetic code. The word proteinogenic is derived from the Latin for 'protein-building.' In 1865, this amino acid was first isolated from protein contained in silk. Silk has a large concentration of it, and the amino acid was named using the Latin word sericum, which means silk. By 1902, the the chemical structure of serine had been determined. The main uses of serine in the human body are to assist in the function of the central nervous system (CNS), as well as with general brain operation. It is present in the myelin sheaths that cover the nerves located in the brain. Without sufficient serine, these sheaths become thin or disappear altogether, leading to an inability for the nerves to transmit messages to other parts of the body.

Acesulfam-K is a calorie-free sugar substitute (artificial sweetener), also known as Acesulfame K or Ace K. It is a food additive and sweetening agent for use in the bakery and beverage industry as well as in diary products.
Beta Carotine (Provitamin) is a yellow-orange food colorant, used in beverages, butter, margarine, dairy products and candies.
Biotin (Vitamin B7 / Vitamin H) is a B-complex vitamin, also known as vitamin B-7 or vitamin H. It is important in a number of metabolic functions in the human body, including cell growth, the synthesis of fatty acids, and the metabolism of the amino acid leucine. Biotin also assists in the Krebs cycle, through which the body converts food into energy, and in the transfer of carbon dioxide within the body. Intestinal bacteria naturally produce this vitamin, and a deficiency is therefore quite rare.
Agar-agar, usually seen abbreviated as agar, is a gelatinous substance derived from certain types of red algae, or seaweed. There are a number of uses for it, although most people are familiar with it as the culture medium in petri dishes. This substance is also perfectly edible, and in addition to appearing in regional cuisine, it is also used as a thickening agent in candies and other foods. Since it is derived from plant material, it has the advantage of being suitable for vegetarians, unlike gelatin, which is derived from animal sources.
