â Blood viscosity â Total blood vessel length â Blood vessel diameter Resistance â¢ Factors that remain relatively constant: â Blood viscosity â¢ The stickiness of blood due to formed elements and plasma proteins â¢ Increased viscosity = increased resistance â Blood vessel length â¢ Longer vessel = greater resistance encountered
Jasmonic acid (JA) is derived from the fatty acid linolenic acid. It is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
The methylmalonic acid (MMA) test may be used to help diagnose an early or mild vitamin B12 deficiency. It may be ordered by itself or along with a homocysteine test as a follow-up to a vitamin B12 test result that is in the lower end of the normal range. MMA is a substance produced in very small amounts in the body.MA is usually ordered, sometimes along with a homocysteine test, when a vitamin B12 test result is in the lower portion of the normal range, especially when a person has symptoms associated with B12 deficiency. Signs and symptoms of B12 deficiency may include: 1  Diarrhea. 2  Dizziness. 3  Fatigue, muscle weakness.
